From the Chairman

75 Years Ago

State Street Research introduced one of the nation's first mutual funds and
pioneered management and research methods that have become industry standard
today. We were also one of the first firms to provide candid commentary on fund
performance. And in recent years, we have been recognized for our prospectus
simplification and plain English communications.

Ralph F. Verni

Our newly designed shareholder reports come out of that same tradition. We think
the educational format, lively graphics and plain English style will make it
easier for you to understand how your fund performed -- and why. We hope you
agree.

We're proud to celebrate 75 years of excellence. But as we get ready to turn the
calendar to the year 2000, our focus is on the future. With this report we are
pleased to announce the appointment of Cathy Dudley as new portfolio manager for
Capital Fund.

We thank you for your confidence.


Sincerely,

/s/ Ralph F. Verni

                            How State Street Research
                             Capital Fund Performed

In a year that was generally favorable for common stocks, the fund generated a
significant return for shareholders, gaining 26.75%.(1) However, that was lower
than the 37.19% return of the Russell mid-cap Growth Index(2).

Reasons for the Fund's Performance

The fund benefited from its investments in technology and consumer services
stocks during the period. The fund's investments in the lagging health care
services sector were a drag on performance. Finally, rising interest rates hurt
financial services stocks, although the fundamental business prospects for the
financial group remained solid.

                                                             [GRAPHIC]

                                                               26.75%

How the Fund is Positioned
for the Period Ahead

Going forward, we continue to focus on three industry sectors: consumer
discretionary, technology and financial services. We have concentrated
approximately 75% of the fund's assets in the different industries within these
three sectors because we believe they should continue to benefit from a strong
economy, high employment and rising discretionary income. We have underweighted
our investment in health care stocks as election year issues and proposed
legislation continue to cloud the sector's near-term prospects, but will revisit
the sector for companies with strong growth characteristics.

Our Outlook

As the U.S. economy continues to move ahead at a slow but steady pace and the
global economy appears poised for a rebound, we believe that earnings growth
should remain strong in the sectors that the fund has emphasized. Higher
interest rates could foil this outlook, but so far the Federal Reserve Board
seems inclined to manage rates with a careful hand.

More Management's Discussion of Fund Performance on pages 6 and 7.  |_|

We are optimistic that a robust U.S. economy and a confident, free-spending
American consumer have the potential to keep this market moving forward for
another year.

Because financial markets and mutual fund strategies are constantly evolving,
it's possible that the fund's holdings, market stance, outlook for various
industries or securities and other matters discussed in this report have changed
since this information was prepared. Portfolio changes should not be considered
recommendations for action by individual investors.

As Good as it Was, as Good as it Gets

Add one more year to one of the most prosperous economic cycles of the century.
1998 ended with a burst of unexpected strength. And although the pace has slowed
just enough to keep inflation under control in 1999, the Federal Reserve Board
made good on its promise to continue to keep a lid on inflation for the future.
The Fed raised short-term interest rates twice between June and August.

But inflationary pressure has begun to mount. Soaring energy prices pushed the
Consumer Price Index up 2.3%, compared to 1.6% one year ago. Households continue
to spend more than they earn as home and auto sales remain robust. Consumer
confidence hit a record high in June, but fell during July, August and
September. For younger and less wealthy Americans, confidence has been on a
downward trend for some time.

Higher interest rates have hurt bonds more than stocks. Most bonds lost ground
as the yield on the 30-year U.S. Treasury benchmark rose above 6.0% in June and
stayed there until late in the period. The S&P 500(4), a broad measure of common
stock performance, rose 27.79%. However, a disproportionate share of the
market's gains belonged to large-company growth stocks. Outside the top 50
stocks, returns have been flat to down for the period. That means the average
investor is looking at a portfolio that is out of step with the S&P 500.

[GRAPHIC] The Way We Think

                              Why this Bull Market
                                 Has Been a Bear
                               for Many Investors

                                                                       [GRAPHIC]

It's been another good year for stocks. But the markets' double digit gains have
not necessarily filtered down to the average investor. The reason? A phenomenon
called market breadth, a technical measure of how many stocks are participating
in the market's current trend. For the past year, market breadth has been
narrow, and that's generally bad.

Beyond the Box Scores

When market breadth is narrow, it means that only a handful of stocks have
shared in the biggest gains. For example, although the S&P 500, a broad measure
of common stock performance, gained 28.7% in 1998, the top 50 stocks in the
index were up 40.0%. Since January, the technology driven Nasdaq has risen a
stunning 25.24% while the average New York Stock Exchange stock has lost 20%.

When the top-performing group of stocks diverges sharply from the average, it
also puts pressure on mutual funds. Funds that owned a broad list of stocks, or
focused on value, or small- or mid-cap stocks, were left out of the party. Even
funds that owned big winners, such as Microsoft, Cisco and Intel, were destined
to lag unless they overweighted them. And most managers are reluctant to
concentrate their investments in any one small group of stocks because it can be
risky and less rewarding over the long term.

Narrow Markets Give Way

Historical data suggest that a narrow market trend is less sustainable than a
broad one. Narrow markets eventually give way. They either broaden to take other
stocks up with them, or they get pulled down under the weight of the rest of the
market.

And the type of investment that leads the market changes. For four years

Univision Communications

is the nation's largest producer of Hispanic programming for television. A
strong demographic story has helped the firm succeed in raising advertising
revenues from major American companies. The Hispanic market is the fastest
growing ethnic market in the U.S. The population is also younger and households
are larger than the national average. Univision Communications is the dominant
player in the Hispanic television market. Earnings have multiplied four-fold
over the past year, and we believe the company continues to have unrealized
growth potential. An outstanding performer, Univision Communications is the
twelfth largest holding in the fund.

J.D. Edwards & Co.

produces enterprise software designed to help mid-sized industrial companies
improve their manufacturing efficiencies. The stock was brought down earlier
this year, along with industry leaders SAP and Baan, two firms that focus on the
large-company segment of the market. The reason? As Y2K approaches, firms began
to balk at the massive spending and sweeping organizational changes associated
with major software conversions. Revenue and profit disappointments resulted,
and J.D. Edwards stock price collapsed. However, we continue to own the stock
because we believe the business is fundamentally sound and we are optimistic
that it will get back on track in the year ahead.

running, large-company growth stocks have been the strongest performers [see
table]. However, between 1993-1994 the Morgan Stanley Capital International EAFE
Index(5), a broad measure of foreign stock market performance, topped the
charts. In 1991-1992, the Russell 2000 Index(6), which tracks the performance of
small stocks, was king of the hill. And in 1990, the last year the stock market
suffered a serious correction, bonds beat stocks.

A Rare Divergence

In fact, the period between 1995-1999 has been an anomaly for the stock market.
The last time there was such a sharp divergence between the top and bottom of
the market was in 1972-1973, when investor attention focused on a narrow band of
stocks known as the "nifty fifty." However, the aftermath of that period was
devastating for some of the most popular stocks of the period, such as Polaroid,
Burroughs, and Emery Air Freight. It's hard to imagine some of today's high
flyers sharing a similar fate, but back then it was hard to imagine they
wouldn't keep going higher.

Lessons of the Past

The key lesson for investors today is that diversification still makes sense.
It doesn't necessarily result in top performance in the short term, but when the
market broadens, you'll already be on board.

A Closer Look [GRAPHIC]

Measuring
Market Breadth

In order to measure the underlying strength of the stock market, technicians
study the relationship between the number of stocks that have advanced versus
the number that have declined. They're also interested in how many stocks are
hitting new highs compared to those hitting new lows. The math is simple. They
subtract decliners from advancers and new lows from new highs and plot the
results on daily charts in order to create trend lines. When few stocks
participate in a trend or trendsetters cluster in a certain segment of the
market, market breadth is narrow and the trend is unconfirmed. When many stocks
are participating, market breadth is broad and the trend is considered strong
and sustainable.

                  Performance Figures as of September 30, 1999

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is never a guarantee of future results, long-term
returns can serve as an important context for evaluating recent
performance.Three ways of measuring long-term performance are cumulative
returns, average annual returns and the change in dollar value over time of a
given investment. Information about these measures follows, while the share
class boxes contain the results of these measures for each share class.

Cumulative Total Return

This represents the total percentage you would have earned or lost if you had
invested a lump sum in the fund and left it there until the end of the period
indicated. Performance would be lower if sales charges were reflected.

Average Annual Total Return

Average annual total return percentage is the rate you would have had to earn
during each year of a given time period-- say, five years-- in order to end up
with the fund's actual cumulative return for those five years. In reality, of
course, fund performance varies from year to year. Because of this, a fund's
actual performance for a given year may be higher or lower than an average
annual performance figure.

$10,000 Over Ten Years

This example is similar to cumulative total return, but uses dollars rather than
percentages, and assumes that the lump sum you invested was $10,000. It also
compares fund performance to the performance of a market index.

A Closer Look [GRAPHIC]

12b-1 fees

12b-1 fees are named after the SEC rule that permits them.

The fund pays 12b-1 fees to cover service and distribution costs. The fees cover
personal services and the maintenance of shareholder accounts.

The fees also cover selling and marketing expenditures for the sale of fund
shares.

The fund pays 12b-1 fees out of its assets, so shareholders see them as an
indirect charge rather than a direct charge.

All of the performance figures on these pages assume reinvestment of dividends
and distributions.

The average annual total returns for the fund also include the effects of any
fees and sales charges that would apply for each share class.

The S&P 500 (officially, the "Standard & Poor's 500 Stock Price Index") is an
unmanaged index of 500 U.S. stocks. The index does not take transaction charges
into consideration. It is not possible to invest directly in the index.

Keep in mind that past performance is no guarantee of future results. The fund's
share price and return will fluctuate and you may have a gain or loss when you
sell your shares.

Class B(1) was introduced January 1, 1999.

The Fund in Detail
- --------

The following pages describe the fund in detail as of the date of this report.
They provide a "snapshot" of the fund's holdings at one moment in time (the
report date), describe the financial dimensions of its operations for the past
fiscal year and give a summary of operations on a per share basis for the past
five fiscal years. There's also an overview of the fund and its business
structure, as well as information on the accounting policies the fund uses in
arriving at the figures it presents here.

                                                                         [PHOTO]

Together, the words and numbers in this section offer a comprehensive picture of
the fund and its recent activities. In fact, the text and notes on pages 9 to 22
are an integral part of the financial statements, which wouldn't be complete
without them.

For more information about the fund's strategies, risks and expenses, check the
fund's prospectus; you'll need to read it before making any investments. The
prospectus also has more details on the fund's share classes and its policies
for shareholder accounts. To get a copy of any State Street Research prospectus,
see the back cover of this report.

Keep in mind that in annual reports, the portfolio holdings and financial
statements are audited, while in semiannual reports they are unaudited.

About the Fund
- --------------------------------------------------------------------------------

Business structure

State Street Research Capital Fund is a mutual fund. A mutual fund allows
shareholders to pool their assets for investment in a portfolio of securities.
This fund is a series of State Street Research Capital Trust, a Massachusetts
business trust and is an open-end management investment company.

Four entities administer the fund's main business functions:

o     The board of trustees oversee the fund with its shareholders' interests in
      mind and have ultimate responsibility for the fund's activities (see
      inside back cover for trustee information).

o     The investment manager, State Street Research & Management Company, is
      responsible for the fund's investment and business activities and receives
      the management fee as compensation.

o     The distributor, State Street Research Investment Services, Inc., sells
      shares of the fund, handles investor inquiries and transaction orders and
      provides other shareholder services.

o     The custodian, State Street Bank and Trust Company, holds fund securities,
      provides data on their market value and handles related services.

The investment manager and the distributor are subsidiaries of Metropolitan Life
Insurance Company, better known as MetLife. State Street Bank and Trust Company
is not affiliated with MetLife (the similarity between its name and the names of
the investment manager and distributor is coincidental). A majority of the
trustees consists of people who are not affiliated with MetLife or any of its
subsidiaries. The distributor pays a portion of its fees to MetLife for services
it provides, including maintaining the accounts of some investors who hold
shares through their firm's employee benefit plans and other sponsored
arrangements.

Goal and strategy

The fund seeks to provide maximum capital appreciation by investing primarily in
common stocks of emerging growth companies and of companies considered to be
undervalued special situations, as determined by the fund's investment manager.

Share classes

The fund generally offers four share classes, each with its own sales charge and
expense structure. The fund also offers an additional class of shares (Class B)
but only to current Class B shareholders through reinvestment of dividends and
distributions or through exchanges from existing Class B accounts of other State
Street Research funds.

The Fund's Accounting Policies
- --------------------------------------------------------------------------------

In keeping with accounting principles generally accepted in the United States,
the fund has used the following policies in preparing the portfolio holdings and
financial statements in this report:

The fund values all portfolio securities as of the date of this report (or, if
that day wasn't a business day, then the most recent business day). The fund
uses the following methods for determining the values of various types of
securities:

      o     Listed securities -- The fund uses the price of the last sale on a
            national securities exchange that was quoted before the close of the
            New York Stock Exchange.

      o     Over-the-counter securities -- The fund uses the closing prices
            quoted on the Nasdaq system. If a security hasn't traded that day,
            or if it is not quoted on the Nasdaq system, the value is set at
            halfway between the closing bid and asked quotations.

      o     Securities maturing within sixty days -- The fund adjusts the value
            of these securities daily, moving them closer to the amount due on
            maturity as the maturity date approaches.

The fund accounts for each purchase and sale of portfolio securities on the
trade date. In calculating realized gains or losses, the fund takes as its cost
basis the identified cost of securities sold.

The fund records investment income from portfolio securities as follows:

      o     Interest -- The fund accrues interest daily as it earns it.

      o     Cash dividends -- The fund accrues these on the ex-dividend date.

The fund may seek additional income by lending portfolio securities to qualified
institutions. By reinvesting any cash collateral it receives in these
transactions, the fund could realize additional gains or loses. If the borrower
fails to return the securities and the collateral has declined in value, the
fund could lose money. The fund accounts for income from the lending of its
securities by including it in interest income. The fund distributes its net
earnings to its shareholders. The fund calculates these distributions using
federal income tax regulations. As a result, they may be different than if the
fund used generally accepted accounting principles. The fund distributes its
earnings on the following schedule:

      o     Dividends from net investment income -- The fund ordinarily declares
            and pays these annually, if any.

      o     Net realized capital gains -- The fund distributes these annually,
            if any, and may make an additional distribution if tax regulations
            make it necessary.

If the fund has no earnings to distribute, it won't make a distribution.

The fund does not intend to pay federal income tax. This is because it intends
to be exempt from taxes under Subchapter M of the Internal Revenue Code, in part
because it makes distributions as described above.

The Fund pays expenses as follows:

      o     Expenses attributed to the fund -- The fund pays these directly.

      The trustees have the authority to issue an unlimited number of fund
      shares, with a $.001 par value per share.

*     Includes $33,948 and $215,789 in sales charges collected by the
      distributor and MetLife.

      as a percentage of these sales but the commissions of $187,228 and
      $378,858 for Class B(1) and Class B, were paid by the distributor, not the
      fund.

***   Includes $15,989 and $861,752 in deferred sales charges collected by the
      distributor for Class B(1) and Class B.

****  Includes $3,455 in deferred sales charges collected by the distributor.

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of State Street Research
Capital Trust and the Shareholders of
State Street Research Capital Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio holdings, and the related statements of operations and of changes
in net assets and the financial highlights present fairly, in all material
respects, the financial position of State Street Research Capital Fund (a series
of State Street Research Capital Trust, hereafter referred to as the "Trust") at
September 30, 1999, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in conformity
with accounting principles generally accepted in the United States. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States, which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits, which included confirmation
of securities at September 30, 1999 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.

From the Chairman

75 Years Ago

State Street Research introduced one of the nation's first mutual funds and
pioneered management and research methods that have become industry standard
today. We were also one of the first firms to provide candid commentary on fund
performance. And in recent years, we have been recognized for our prospectus
simplification and plain English communications.

[PHOTO]
Ralph F. Verni

Our newly designed shareholder reports come out of that same tradition. We think
the educational format, lively graphics and plain English style will make it
easier for you to understand how your fund performed -- and why. We hope you
agree.

We're proud to celebrate 75 years of excellence. But as we get ready to turn the
calendar to the year 2000, our focus is on the future. We thank you for your
confidence, and we look forward to continuing to help you work toward your
financial goals in the years ahead.

Sincerely,


/s/ Ralph F. Verni

12 Month Review Management's Discussion of Fund Performance Part 1

                            How State Street Research
                         Emerging Growth Fund Performed

The environment for stocks was generally favorable throughout the year, which
helped the fund return 29.10%.(1) The performance was slightly lower than the
Russell 2000 Growth Index(2), which gained 32.63% over the same period.

Reasons for the Fund's Performance

The fund's significant investment in technology stocks contributed to its strong
performance during the year. In particular, the fund benefited by emphasizing
the rapidly growing Internet sector and Internet infrastructure-related stocks.
Health care delivered mixed results as one of the fund's best performers was
Biovail, a biotechnology company; and one of the worst performers was a medical
delivery firm, Total Renal Care, which suffered a series of earnings setbacks.
The fund's financial services stocks were hurt by rising interest rates and were
a drag on performance.

                                                       29.10%

How the Fund is Positioned
for the Period Ahead

We continue to favor rapidly growing companies with high quality management,
especially those in the consumer and technology sectors.

Our Outlook

The U.S. economy is in the ninth year of its current business cycle, and so far
conditions remain strong -- but not too strong. However, we will monitor the
situation, especially in regards to possible changes in interest rates. With a
recent track record of more positive earnings revisions and fewer negative
surprises, small company stocks offer strong growth prospects for the period
ahead.

As Good as it Was, as Good as it Gets

Add one more year to one of the most prosperous economic cycles of the century.
1998 ended with a burst of unexpected strength. And although the pace has slowed
just enough to keep inflation under control in 1999, the Federal Reserve Board
made good on its promise to continue to keep a lid on inflation for the future.
The Fed raised short-term interest rates twice between June and August.

But inflationary pressure has begun to mount. Soaring energy prices pushed the
Consumer Price Index up 2.3%, compared to 1.6% one year ago. Households continue
to spend more than they earn as home and auto sales remain robust. Consumer
confidence hit a record high in June, but fell during July, August and
September. For younger and less wealthy Americans, confidence has been on a
downward trend for some time.

Higher interest rates have hurt bonds more than stocks. Most bonds lost ground
as the yield on the 30-year U.S. Treasury benchmark rose above 6.0% in June and
stayed there until late in the period. The S&P 500(4), a broad measure of common
stock performance, rose 27.79%. However, a disproportionate share of the
market's gains belonged to large-company growth stocks. Outside the top 50
stocks, returns have been flat to down for the period. That means the average
investor is looking at a portfolio that is out of step with the S&P 500.

[GRAPHIC] The Way We Think

                              Why this Bull Market
                                 Has Been a Bear
                               for Many Investors

                                                                       [GRAPHIC]

It's been another good year for stocks. But the markets' double digit gains have
not necessarily filtered down to the average investor. The reason? A phenomenon
called market breadth, a technical measure of how many stocks are participating
in the market's current trend. For the past year, market breadth has been
narrow, and that's generally bad.

Beyond the Box Scores

When market breadth is narrow, it means that only a handful of stocks have
shared in the biggest gains. For example, although the S&P 500, a broad measure
of common stock performance, gained 28.7% in 1998, the top 50 stocks in the
index were up 40.0%. Since January, the technology driven Nasdaq has risen a
stunning 25.24% while the average New York Stock Exchange stock has lost 20%.

When the top-performing group of stocks diverges sharply from the average, it
also puts pressure on mutual funds. Funds that owned a broad list of stocks, or
focused on value, or small- or mid-cap stocks, were left out of the party. Even
funds that owned big winners, such as Microsoft, Cisco and Intel, were destined
to lag unless they overweighted them. And most managers are reluctant to
concentrate their investments in any one small group of stocks because it can be
risky and less rewarding over the long term.

Narrow Markets Give Way

Historical data suggest that a narrow market trend is less sustainable than a
broad one. Narrow markets eventually give way. They either broaden to take other
stocks up with them, or they get pulled down under the weight of the rest of the
market.

And the type of investment that leads the market changes. For four years

Abacus Direct

provides purchase information to direct marketers. The company gathers data on
purchases from direct mail retailers then resells it to marketers seeking to
identify likely customers of their own products. We zeroed in on Abacus Direct
because it was part of the business services group, which we had identified
because of the group's predictable and highly visible earnings growth. We liked
Abacus because of its core business and the potential it offered for directing
marketing applications through the Internet. Our confidence was rewarded as the
stock price rose on its own merits following our purchase of the stock in
February. Then, it took off when Double Click, an online Internet advertising
company, made an offer to acquire it late in the period. We believe the
acquisition would create an attractive combined entity with significant future
growth potential, and we continue to own the stock.

Total Renal Care

is one of the leading providers of dialysis and related services for chronic
kidney failure. With a substantial market to pursue -- and a significant market
share -- the company looked attractive to us because of its track record of
strong earnings growth. However, a series of earnings disappointments have
raised questions about the company's financial controls and management
credibility. As a result, we are reevaluating our investment in the company. At
the end of the period, Total Renal Care represented less than 1% of the
portfolio. However, its declining stock price dealt a significant loss to the
fund's performance during the year.

running, large-company growth stocks have been the strongest performers [see
table]. However, between 1993-1994 the Morgan Stanley Capital International EAFE
Index(6), a broad measure of foreign stock market performance, topped the
charts. In 1991-1992, the Russell 2000 Index(7), which tracks the performance of
small stocks, was king of the hill. And in 1990, the last year the stock market
suffered a serious correction, bonds beat stocks.

A Rare Divergence

In fact, the period between 1995-1999 has been an anomaly for the stock market.
The last time there was such a sharp divergence between the top and bottom of
the market was in 1972-1973, when investor attention focused on a narrow band of
stocks known as the "nifty fifty." However, the aftermath of that period was
devastating for some of the most popular stocks of the period, such as Polaroid,
Burroughs and Emery Air Freight. It's hard to imagine some of today's high
flyers sharing a similar fate, but back then it was hard to imagine they
wouldn't keep going higher.

Lessons of the Past

The key lesson for investors today is that diversification still makes sense.
It doesn't necessarily result in top performance in the short term, but when the
market broadens, you'll already be on board.

A Closer Look [GRAPHIC]

Measuring Market Breadth

In order to measure the underlying strength of the stock market, technicians
study the relationship between the number of stocks that have advanced versus
the number that have declined. They're also interested in how many stocks are
hitting new highs compared to those hitting new lows. The math is simple. They
subtract decliners from advancers and new lows from new highs and plot the
results on daily charts in order to create trend lines. When few stocks
participate in a trend or trendsetters cluster in a certain segment of the
market, market breadth is narrow and the trend is unconfirmed. When many stocks
are participating, market breadth is broad and the trend is considered strong
and sustainable.

                  Performance Figures as of September 30, 1999

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is never a guarantee of future results, long-term
returns can serve as an important context for evaluating recent performance.
Three ways of measuring long-term performance are cumulative returns, average
annual returns and the change in dollar value over time of a given investment.
Information about these measures follows, while the share class boxes contain
the results of these measures for each share class.

Cumulative Total Return

This represents the total percentage you would have earned or lost if you had
invested a lump sum in the fund and left it there until the end of the period
indicated. Performance would be lower if sales charges were reflected.

Average Annual Total Return

Average annual total return percentage is the rate you would have had to earn
during each year of a given time period -- say, five years -- in order to end up
with the fund's actual cumulative return for those five years. In reality, of
course, fund performance varies from year to year. Because of this, a fund's
actual performance for a given year may be higher or lower than an average
annual performance figure.

$10,000 Over Life of Fund

This example is similar to cumulative total return, but uses dollars rather than
percentages, and assumes that the lump sum you invested was $10,000. It also
compares fund performance to the performance of a market index.

A Closer Look [GRAPHIC]

12b-1 fees

12b-1 fees are named after the SEC rule that permits them.

The fund pays 12b-1 fees to cover service and distribution costs. The fees cover
personal services and the maintenance of shareholder accounts.

The fees also cover selling and marketing expenditures for the sale of fund
shares.

The fund pays 12b-1 fees out of its assets, so shareholders see them as an
indirect charge rather than a direct charge.

All of the performance figures on these pages assume reinvestment of dividends
and distributions.

The average annual total returns for the fund also include the effects of any
fees and sales charges that would apply for each share class.

The S&P 500 (officially, the "Standard & Poor's 500 Stock Price Index") is an
unmanaged index of 500 U.S. stocks. The index does not take transaction charges
into consideration. It is not possible to invest directly in the index.

Keep in mind that past performance is no guarantee of future results. The fund's
share price and return will fluctuate and you may have a gain or loss when you
sell your shares.

Class B(1) was introduced January 1, 1999.

About the Fund
- --------------------------------------------------------------------------------

Business structure

State Street Research Emerging Growth Fund is a mutual fund that allows
shareholders to pool their assets for investment in a portfolio of securities.
This fund is a series of State Street Research Capital Trust, a Massachusetts
business trust and is an open-end management investment company.

Four entities administer the fund's main business functions:

o     The board of trustees oversee the fund with its shareholders' interests in
      mind and have ultimate responsibility for the fund's activities (see
      inside back cover for trustee information).

o     The investment manager, State Street Research & Management Company, is
      responsible for the fund's investment and business activities and receives
      the management fee as compensation.

o     The distributor, State Street Research Investment Services, Inc., sells
      shares of the fund, handles investor inquiries and transaction orders and
      provides other shareholder services.

o     The custodian, State Street Bank and Trust Company, holds fund securities,
      provides data on their market value and handles related services.

The investment manager and the distributor are subsidiaries of Metropolitan Life
Insurance Company, better known as MetLife. State Street Bank and Trust Company
is not affiliated with MetLife (the similarity between its name and the names of
the investment manager and distributor is coincidental). A majority of the
trustees consists of people who are not affiliated with MetLife or any of its
subsidiaries. The distributor pays a portion of its fees to MetLife for services
it provides, including maintaining the accounts of some investors who hold
shares through their firm's employee benefit plans and other sponsored
arrangements.

Goal and strategy

The fund seeks to provide growth of capital. In seeking to achieve its
investment objective, the fund invests primarily in the equity securities of
emerging growth and small capitalization companies.

Share classes

The fund generally offers four share classes, each with its own sales charge and
expense structure. The fund also offers an additional class of shares (Class B)
but only to current Class B shareholders through reinvestment of dividends and
distributions or through exchanges from existing Class B accounts of other State
Street Research funds.

The Fund's Accounting Policies
- --------------------------------------------------------------------------------

In keeping with accounting principles generally accepted in the United States,
the fund has used the following policies in preparing the portfolio holdings and
financial statements in this report:

The fund values all portfolio securities as of the date of this report (or, if
that day wasn't a business day, then the most recent business day). The fund
uses the following methods for determining the values of various types of
securities:

      o     Listed securities -- The fund uses the price of the last sale on a
            national securities exchange that was quoted before the close of the
            New York Stock Exchange.

      o     Over-the-counter securities -- The fund uses the closing prices
            quoted on the Nasdaq system. If a security hasn't traded that day,
            or if it is not quoted on the Nasdaq system, the value is set at
            halfway between the closing bid and asked quotations.

      o     Securities maturing within sixty days -- The fund adjusts the value
            of these securities daily, moving them closer to the amount due on
            maturity as the maturity date approaches.

The fund accounts for each purchase and sale of portfolio securities on the
trade date. In calculating realized gains or losses, the fund takes as its cost
basis the identified cost of securities sold.

The fund records investment income from portfolio securities as follows:

      o     Interest -- The fund accrues interest daily as it earns it.

      o     Cash dividends -- The fund accrues these on the ex-dividend date.

The fund may seek additional income by lending portfolio securities to qualified
institutions. By reinvesting any cash collateral it receives in these
transactions, the fund could realize additional gains or losses. If the borrower
fails to return the securities and the collateral has declined in value, the
fund could lose money. The fund accounts for income from the lending of its
securities by including it in interest income.

The fund distributes its net earnings to its shareholders. The fund calculates
these distributions using federal income tax regulations. As a result, they may
be different than if the fund used generally accepted accounting principles. The
fund distributes its earnings on the following schedule:

      o     Dividends from net investment income -- The fund ordinarily declares
            and pays these annually, if any.

      o     Net realized capital gains -- The fund distributes these annually,
            if any, and may make an additional distribution if tax regulations
            make it necessary.

If the fund has no earnings to distribute, it won't make a distribution.

The fund does not intend to pay federal income tax. This is because it intends
to be exempt from taxes under Subchapter M of the Internal Revenue Code, in part
because it makes distributions as described above.

The Fund pays expenses as follows:

      o     Expenses attributed to the fund -- The fund pays these directly.
            Examples of these expenses include the management fee, transfer
            agent fee, custodian fee and distribution and service fees.

      o     Expenses attributed to the trust of which the fund is a series --
            These expenses are divided up among all funds in the trust. Each
            fund pays a proportional share. Examples of these expenses include
            the legal fees and trustees fees.

The fund has used certain estimates and assumptions in preparing this report.
Although they are necessary in order to follow generally accepted accounting
principles, these estimates and assumptions affect several key areas, including
the reported amounts of assets and liabilities and income and expenses. Actual
results could differ from those estimates.

The fund's securities and investment practices carry certain risks.

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of State Street Research
Capital Trust and the Shareholders of
State Street Research Emerging Growth Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio holdings, and the related statements of operations and of changes
in net assets and the financial highlights present fairly, in all material
respects, the financial position of State Street Research Emerging Growth Fund
(a series of State Street Research Capital Trust, hereafter referred to as the
"Trust") at September 30, 1999, and the results of its operations, the changes
in its net assets and the financial highlights for the periods indicated, in
conformity with accounting principles generally accepted in the United States.
These financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States, which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits, which included confirmation
of securities at September 30, 1999 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.

From the Chairman

75 Years Ago

State Street Research introduced one of the nation's first mutual funds and
pioneered management and research methods that have become industry standard
today. We were also one of the first firms to provide candid commentary on fund
performance. And in recent years, we have been recognized for our prospectus
simplification and plain English communications.

[PHOTO]

Ralph F. Verni

Our newly designed shareholder reports come out of that same tradition. We think
the educational format, lively graphics and plain English style will make it
easier for you to understand how your fund performed -- and why. We hope you
agree.

We're proud to celebrate 75 years of excellence. But as we get ready to turn the
calendar to the year 2000, our focus is on the future. We thank you for your
confidence, and we look forward to continuing to help you work toward your
financial goals in the years ahead.

Sincerely,


/s/ Ralph F. Verni

                            How State Street Research
                              Aurora Fund Performed

The environment for stocks was generally favorable throughout the year, which
helped the fund return 22.88%.(1) The fund outperformed its peer group, the
Lipper Small-Cap Value Fund Average, which returned 12.33% for the year. Also,
it significantly outperformed the Russell 2000 Value Index(2), which gained a
modest 5.83% for the period.

Reasons for the Fund's Performance

A significant portion of the fund's assets was concentrated in cyclical
industries. And although these stocks failed to keep up with areas of the market
associated with technology, which delivered spectacular gains for the year, they
did respectably well. The fund's investment in real estate investment trusts got
off to a strong start early in the year, but the group gave back most of its
gains as uncertainty about interest rates and the economy materialized later in
the period.

                                                             [GRAPHIC]

                                                               22.88%

How the Fund is Positioned
for the Period Ahead

We continue to focus on individual companies with little regard to the economy
or the markets. We search for relatively small companies that are selling at
reasonable prices and offer the opportunity for strong future gains.

Our Outlook

At least a third of the fund is invested in companies that are associated with
industrial materials, auto parts, chemicals, electronics and machinery. And
while these areas are not growing at the pace of hot industries such as
biotechnology and the Internet, we believe the companies we own represent good
value for the period ahead.

As Good as it Was, as Good as it Gets

Add one more year to one of the most prosperous economic cycles of the century.
1998 ended with a burst of unexpected strength. And although the pace has slowed
just enough to keep inflation under control in 1999, the Federal Reserve Board
made good on its promise to continue to keep a lid on inflation for the future.
The Fed raised short-term interest rates twice between June and August.

But inflationary pressure has begun to mount. Soaring energy prices pushed the
Consumer Price Index up 2.3%, compared to 1.6% one year ago. Households continue
to spend more than they earn as home and auto sales remain robust. Consumer
confidence hit a record high in June, but fell during July, August and
September. For younger and less wealthy Americans, confidence has been on a
downward trend for some time.

Higher interest rates have hurt bonds more than stocks. Most bonds lost ground
as the yield on the 30-year U.S. Treasury benchmark rose above 6.0% in June and
stayed there until late in the period. The S&P 500(4), a broad measure of common
stock performance, rose 27.79%. However, a disproportionate share of the
market's gains belonged to large-company growth stocks. Outside the top 50
stocks, returns have been flat to down for the period. That means the average
investor is looking at a portfolio that is out of step with the S&P 500.

[GRAPHIC] The Way We Think

                              Why this Bull Market
                                 Has Been a Bear
                               for Many Investors

                                                                       [GRAPHIC]

It's been another good year for stocks. But the markets' double digit gains have
not necessarily filtered down to the average investor. The reason? A phenomenon
called market breadth, a technical measure of how many stocks are participating
in the market's current trend. For the past year, market breadth has been
narrow, and that's generally bad.

Beyond the Box Scores

When market breadth is narrow it means that only a handful of stocks have shared
in the biggest gains. For example, although the S&P 500, a broad measure of
common stock performance, gained 28.7% in 1998, the top 50 stocks in the index
were up 40.0%. Since January, the technology driven Nasdaq has risen a stunning
25.24% while the average New York Stock Exchange stock has lost 20%.

When the top-performing group of stocks diverges sharply from the average, it
also puts pressure on mutual funds. Funds that owned a broad list of stocks, or
focused on value, or small- or mid-cap stocks, were left out of the party. Even
funds that owned big winners, such as Microsoft, Cisco and Intel, were destined
to lag unless they overweighted them. And most managers are reluctant to
concentrate their investments in any one small group of stocks because it can be
risky and less rewarding over the long term.

Narrow Markets Give Way

Historical data suggest that a narrow market trend is less sustainable than a
broad one. Narrow markets eventually give way. They either broaden to take other
stocks up with them, or they get pulled down under the weight of the rest of the
market.

And the type of investment that leads the market changes. For four years

Wyman-Gordon Company

is the dominant player in the market for forged aerospace components. We
invested in the Grafton, Massachusetts company after a series of internal
problems drove the company's stock price down from the high $20s to the low
single digits within a year. The depressed stock price, plus the company's
unique market position, also made Wyman-Gordon an attractive takeover candidate.
Recently, Precision Castparts, a maker of cast (versus forged) aerospace parts
made a bid to acquire the company at $20/share. It's an opportunity for
Precision to expand its market presence buying the leading franchise in forged
parts at a price that represents about 50% of the company's annual revenues.
Wyman-Gordon has made a significant contribution to the performance of State
Street Research Aurora Fund during the period.

Kevco, Inc.

distributes bathroom fixtures and hardware to makers of manufactured housing. We
were attracted to the company because it had a solid base of business and
because the market for manufactured housing was growing, the beneficiary of a
strong economy and low interest rates.

During the year Kevco acquired Patrick Industries, a competitor that offered the
potential to expand Kevco's market share. However, instead of producing a
desirable synergy, the acquisition was difficult for Kevco to assimilate. And
because it had financed the purchase with debt, the acquisition also weakened
its own financial position. Plus, the manufactured housing market contracted
during the year, which served to make a bad situation even worse. As a result,
we liquidated our interest in the company a loss.

running, large-company growth stocks have been the strongest performers [see
table]. However, between 1993-1994 the Morgan Stanley Capital International EAFE
Index(6), a broad measure of foreign stock market performance, topped the
charts. In 1991-1992, the Russell 2000 Index(7), which tracks the performance of
small stocks, was king of the hill. And in 1990, the last year the stock market
suffered a serious correction, bonds beat stocks.

A Rare Divergence

In fact, the period between 1995-1999 has been an anomaly for the stock market.
The last time there was such a sharp divergence between the top and bottom of
the market was in 1972-1973, when investor attention focused on a narrow band of
stocks known as the "nifty fifty." However, the aftermath of that period was
devastating for some of the most popular stocks of the period, such as Polaroid,
Burroughs, and Emery Air Freight. It's hard to imagine some of today's high
flyers sharing a similar fate, but back then it was hard to imagine they
wouldn't keep going higher.

Lessons of the Past

The key lesson for investors today is that diversification still makes sense.
It doesn't necessarily result in top performance in the short term, but when the
market broadens, you'll already be on board.

A Closer Look [GRAPHIC]

Measuring
Market Breadth

In order to measure the underlying strength of the stock market, technicians
study the relationship between the number of stocks that have advanced versus
the number that have declined. They're also interested in how many stocks are
hitting new highs compared to those hitting new lows. The math is simple. They
subtract decliners from advancers and new lows from new highs and plot the
results on daily charts in order to create trend lines. When few stocks
participate in a trend or trendsetters cluster in a certain segment of the
market, market breadth is narrow and the trend is unconfirmed. When many stocks
are participating, market breadth is broad and the trend is considered strong
and sustainable.

                  Performance Figures as of September 30, 1999

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is never a guarantee of future results, long-term
returns can serve as an important context for evaluating recent performance.
Three ways of measuring long-term performance are cumulative returns, average
annual returns and the change in dollar value over time of a given investment.
Information about these measures follows, while the share class boxes contain
the results of these measures for each share class.

Cumulative Total Return

This represents the total percentage you would have earned or lost if you had
invested a lump sum in the fund and left it there until the end of the period
indicated. Performance would be lower if sales charges were reflected.

Average Annual Total Return

Average annual total return percentage is the rate you would have had to earn
during each year of a given time period-- say, five years-- in order to end up
with the fund's actual cumulative return for those five years. In reality, of
course, fund performance varies from year to year. Because of this, a fund's
actual performance for a given year may be higher or lower than an average
annual performance figure.

$10,000 Over Life of Fund

This example is similar to cumulative total return, but uses dollars rather than
percentages, and assumes that the lump sum you invested was $10,000. It also
compares fund performance to the performance of a market index.

A Closer Look [GRAPHIC]

12b-1 fees

12b-1 fees are named after the SEC rule that permits them.

The fund pays 12b-1 fees to cover service and distribution costs. The fees cover
personal services and the maintenance of shareholder accounts.

The fees also cover selling and marketing expenditures for the sale of fund
shares.

The fund pays 12b-1 fees out of its assets, so shareholders see them as an
indirect charge rather than a direct charge.

All of the performance figures on these pages assume reinvestment of dividends
and distributions.

The average annual total returns for the fund also include the effects of any
fees and sales charges that would apply for each share class.

The S&P 500 (officially, the "Standard & Poor's 500 Stock Price Index") is an
unmanaged index of 500 U.S. stocks. The index does not take transaction charges
into consideration. It is not possible to invest directly in the index.

Keep in mind that past performance is no guarantee of future results. The fund's
share price and return will fluctuate and you may have a gain or loss when you
sell your shares.

Class B(1) was introduced January 1, 1999.

The following pages describe the fund in detail as of the date of this report.
They provide a "snapshot" of the fund's holdings at one moment in time (the
report date), describe the financial dimensions of its operations for the past
fiscal year and give a summary of operations on a per share basis for the past
five fiscal years. There's also an overview of the fund and its business
structure, as well as information on the accounting policies the fund uses in
arriving at the figures it presents here.

                                                                         [PHOTO]

Together, the words and numbers in this section offer a comprehensive picture of
the fund and its recent activities. In fact, the text and notes on pages 9 to 24
are an integral part of the financial statements, which wouldn't be complete
without them.

For more information about the fund's strategies, risks and expenses, check the
fund's prospectus; you'll need to read it before making any investments. The
prospectus also has more details on the fund's share classes and its policies
for shareholder accounts. To get a copy of any State Street Research prospectus,

statements are audited, while in semiannual reports they are unaudited.

About the Fund
- --------------------------------------------------------------------------------

Business structure

State Street Research Aurora Fund is a mutual fund. A mutual fund allows
shareholders to pool their assets for investment in a portfolio of securities.
This fund is a series of State Street Research Capital Trust, a Massachusetts
business trust and is an open-end management investment company.

Four entities administer the fund's main business functions:

o     The board of trustees oversee the fund with its shareholders' interests in
      mind and have ultimate responsibility for the fund's activities (see p.25
      for trustee information).

o     The investment manager, State Street Research & Management Company, is
      responsible for the fund's investment and business activities and receives
      the management fee as compensation.

o     The distributor, State Street Research Investment Services, Inc., sells
      shares of the fund, handles investor inquiries and transaction orders and
      provides other shareholder services.

o     The custodian, State Street Bank and Trust Company, holds fund securities,
      provides data on their market value and handles related services.

The investment manager and the distributor are subsidiaries of Metropolitan Life
Insurance Company, better known as MetLife. State Street Bank and Trust Company
is not affiliated with MetLife (the similarity between its name and the names of
the investment manager and distributor is coincidental). A majority of the
trustees consists of people who are not affiliated with MetLife or any of its
subsidiaries. The distributor pays a portion of its fees to MetLife for services
it provides, including maintaining the accounts of some investors who hold
shares through their firm's employee benefit plans and other sponsored
arrangements.

Goal and strategy

The fund seeks to provide high total return, consisting principally of capital
appreciation. In seeking to achieve its objective, the fund searches for those
companies that appear to be trading below their true worth.

Share classes

The fund generally offers four share classes, each with its own sales charge and
expense structure. The fund also offers an additional class of shares (Class B)
but only to current Class B shareholders through reinvestment of dividends and
distributions or through exchanges from existing Class B accounts of other State
Street Research funds.

The Fund's Accounting Policies
- --------------------------------------------------------------------------------

In keeping with accounting principles generally accepted in the United States,
the fund has used the following policies in preparing the portfolio holdings and
financial statements in this report:

The fund values all portfolio securities as of the date of this report (or, if
that day wasn't a business day, then the most recent business day). The fund
uses the following methods for determining the values of various types of
securities:

      o     Listed securities -- The fund uses the price of the last sale on a
            national securities exchange that was quoted before the close of the
            New York Stock Exchange.

      o     Over-the-counter securities -- The fund uses the closing prices
            quoted on the Nasdaq system. If a security hasn't traded that day,
            or if it is not quoted on the Nasdaq system, the value is set at
            halfway between the closing bid and asked quotations.

      o     Securities maturing within sixty days -- The fund adjusts the value
            of these securities daily, moving them closer to the amount due on
            maturity as the maturity date approaches.

      o     Other securities -- The fund prices these securities at fair value
            under procedures established and supervised by the trustees.

The fund accounts for each purchase and sale of portfolio securities on the
trade date. In calculating realized gains or losses, the fund takes as its cost
basis the identified cost of securities sold.

The fund records investment income from portfolio securities as follows:

      o     Interest -- The fund accrues interest daily as it earns it.

      o     Cash dividends -- The fund accrues these on the ex-dividend date.

The fund may seek additional income by lending portfolio securities to qualified
institutions. By reinvesting any cash collateral it receives in these
transactions, the fund could realize additional gains or losses. If the borrower
fails to return the securities and the collateral has declined in value, the
fund could lose money. The fund accounts for income from the lending of its
securities by including it in interest income.

The fund distributes its net earnings to its shareholders. The fund calculates
these distributions using federal income tax regulations. As a result, they may
be different than if the fund used generally accepted accounting principles. The
fund distributes its earnings on the following schedule:

      o     Dividends from net investment income -- The fund ordinarily declares
            and pays these annually, if any.

      o     Net realized capital gains -- The fund distributes these annually,
            if any, and may make an additional distribution if tax regulations
            make it necessary.

If the fund has no earnings to distribute, it won't make a distribution.

The fund does not intend to pay federal income tax. This is because it intends
to be exempt from taxes under Subchapter M of the Internal Revenue Code, in part
because it makes distributions as described above.

The Fund pays expenses as follows:

      o     Expenses attributed to the fund -- The fund pays these directly.
            Examples of these expenses include the management fee, transfer
            agent fee, custodian fee and distribution and service fees.

      o     Expenses attributed to the trust of which the fund is a series --
            These expenses are divided up among all funds in the trust. Each
            fund pays a proportional share. Examples of these expenses include
            the legal fees and trustees fees.

The fund has used certain estimates and assumptions in preparing this report.
Although they are necessary in order to follow generally accepted accounting
principles, these estimates and assumptions affect several key areas, including
the reported amounts of assets and liabilities and income and expenses. Actual
results could differ from those estimates.

The fund's securities and investment practices carry certain risks.

      The trustees have the authority to issue an unlimited number of fund
      shares, with a $.001 par value per share.

*     Includes $226,638 and $193,838 in sales charges collected by the
      distributor and MetLife.

      as a percentage of these sales but the commissions of $119,330 and
      $210,355 for Class B(1) and Class B, were paid by the distributor, not the
      fund.

***   Includes $16,804 and $928,580 in deferred sales charges collected by the
      distributor for Class B(1) and Class B.

****  Includes $15,346 in deferred sales charges collected by the distributor.

Report of Independent Accountants
- --------------------------------------------------------------------------------

To the Trustees of State Street Research
Capital Trust and the Shareholders of
State Street Research Aurora Fund

In our opinion, the accompanying statement of assets and liabilities, including
the portfolio holdings, and the related statements of operations and of changes
in net assets and the financial highlights present fairly, in all material
respects, the financial position of State Street Research Aurora Fund (a series
of State Street Research Capital Trust, hereafter referred to as the "Trust") at
September 30, 1999, and the results of its operations, the changes in its net
assets and the financial highlights for the periods indicated, in conformity
with accounting principles generally accepted in the United States. These
financial statements and financial highlights (hereafter referred to as
"financial statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with auditing standards generally accepted in the United States, which require
that we plan and perform the audit to obtain reasonable assurance about whether
the financial statements are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements, assessing the accounting principles used and
significant estimates made by management, and evaluating the overall financial
statement presentation. We believe that our audits, which included confirmation
of securities at September 30, 1999 by correspondence with the custodian and
brokers, provide a reasonable basis for the opinion expressed above.

Glossary

      12b-1 fees -- Fees paid from mutual fund assets for personal services and
      for the maintenance of shareholder accounts and distribution and marketing
      expenses. The fees are named after the SEC rule that permits them.

      average shares method -- The practice of basing a fund's calculations for
      a given period on the average number of shares that were outstanding
      during that period.

      Nasdaq -- The stock price quotation system operated by the National
      Association of Securities Dealers. The Nasdaq system operates as a
      clearing house for transaction data about stocks that are traded "over the
      counter" around the U.S.

      New York Stock Exchange -- The largest stock exchange in the United
      States, and the place where many of the largest company stocks are listed.
      Unlike the Nasdaq system, the NYSE is a physical exchange, with all
      trading occurring on the exchange's trading floor on Wall Street.

      Principal Amount -- With bonds and certain other debt securities, the
      amount of the underlying principal of the security. When the security
      matures, the issuer is obligated to repay this amount to the holder of the
      security. Also called "face value" or "par value".
