From the Chairman

What will you remember about the 1990s? A string of good years for the stock
market? The Y2K phenomenon? A generation from now, most of the events that made
headlines during the decade are likely to pale compared to the birth of the
Internet and new communications technologies.

And just as technology was the driving force behind the U.S. econ-omy and the
stock market last year, it also figured strongly in the gains of State Street
Research Investment Trust. As you read this annual report, we hope you'll come
away with a better understanding of our perspective on technology and where we
see opportunities for the years ahead.

Technology has changed our world, but some things don't change: our emphasis on
fundamental research and our commitment to helping you reach your long-term
goals. As always, thank you for investing with State Street Research.

Sincerely,


/s/ Ralph F. Verni

                            How State Street Research
                           Investment Trust Performed

1999 was a good year for State Street Research Investment Trust. The fund
returned 19.75%(1), significantly higher than its old peer group, the Lipper
Growth & Income Funds Average(2), which rose 13.76% for the year ended December
31, 1999. The fund's new Lipper category, the Large-Cap Core Funds Average(2),
returned 22.30% for the same period. Its performance was just short of the S&P
500, which gained 21.03%.(3)

Reasons for the Fund's Performance

Technology stocks drove the performance of the market during the year and
accounted for much of Investment Trust's gains. The fund was well-represented in
technology's strong performers, such as EMC and Cisco Systems. Amgen and
Genentech, leaders in biotechnology, helped to contribute to the fund's positive
year-end returns.

Our investments in media and advertising companies also generated attractive
gains. As a group, media companies were helped by a robust U.S. economy and
higher corporate spending on advertising.

The financial sector was hurt as rising interest rates brought prices down on
many financial stocks. The fund's investment in insurance stocks were a drag on
performance. However, we zeroed in on Citigroup and American Express, which did
well despite an unfavorable environment.

Outlook

Our outlook going forward is positive. As the U.S. economy undergoes dynamic,
rapid change, we believe we must be more aggressive to keep pace with an
evolving market. However, our core philosophy has not changed. We will continue
to focus on high quality companies that have strong franchises and are leaders
in their respective markets.

The network generated strong results across all business lines. That, plus
expectations that its pending merger with Viacom could create a powerful
combined media franchise, raised the stock price.

Ace Ltd.

This Bermuda-based insurance company was hurt by overall weakness in financial
stocks plus fundamental weakness in the specialty insurance sector.

However, we continue to own it. Its business prospects remain strong and any
improvement in insurance pricing could lift the stock.

[GRAPHIC] The Way We Think

                                  Technology's
                                  Long Rise--
                                    Can it Continue?

                                                                       [GRAPHIC]

It led the stock market with dazzling gains. It gave birth to dot-com fever and
day-trading in the space of the same year. It's changed the way we work, the way
we play, the way we live. When you talk about technology, it's hard to find
enough superlatives to describe its impact.

Yet, technology is no overnight sensation. For more than 25 years, it has been
the driving force behind the economies and investment markets of the U.S. and
most industrialized nations. From main-frame computers in the 1970s, to personal
computers and software in the 1980s, to wireless communications and the Internet
in the 1990s, technology has ruled.

Beyond Big

But something happened in 1997. What seemed like a strong, powerful trend took a
turn that no one could have predicted. "In December 1997, technology accounted
for just under 14% of the S&P 500. At the end of 1999, it accounted for 30%,"
says John Wilson, portfolio manager of State Street Research Investment Trust.

According to Wilson, technology's dominance was pervasive in 1999:

o     Thirteen of the stock market's fifteen top-performing, large-company
      stocks were technology-related. A similar pattern existed among
      small-company stocks -- many of which hardly qualified as "small" by the
      time the year was over.

o     The technology-laden Nasdaq rose an impressive 85.59% compared to a gain
      of 21.03% for the S&P 500.

Prosperity Propels U.S. Toward Record

Although the pace of economic growth slowed somewhat from 1998 to 1999,
America's gross domestic product grew at a rate faster than the Federal Reserve
Board considers comfortable to control inflation. As a result, it raised
interest rates three times in the second half of the year, leaving the federal
funds rate at 5.5% and the discount rate at 5.0% -- both up 3/4% or 75 basis
points.

Consumers Keep it Up Higher interest rates did not, however, seem to slow the
American consumer. Households continued to spend more on homes, autos and retail
goods; although the rate of growth slowed as the year came to an end. Now, the
U.S. economy is closing in on an economic record: If positive growth continues
through the first two months of 2000, the current expansion will outdistance the
longest expansion of economic growth in the 20th century, which lasted 106
months and occurred between February 1961 and December 1969.

Inflationary Pressures Pick Up That said, inflationary pressures have also
picked up. Soaring energy prices pushed inflation up to 2.6%, compared to 1.6%
one year ago, as measured by the Consumer Price Index. If you leave energy out
of the mix, inflation shows a more modest increase to 2.2%. Yet, despite rising
inflation and a cautious Fed policy, the U.S. stock market continued to rise
while bonds stumbled in reaction to higher rates, inflation fears and Y2K
uncertainty.

If you dissect the S&P 500, you'll find that S&P 500 technology issues rose
74.6% while non-tech issues eked out 4.5% -- lower than the average yield on a
money market mutual fund.

o     Nine of the best-performing IPOs (Initial Public Offerings) in 1999 were
      technology companies while non-technology IPOs struggled.

o     Of 234 companies that made 1999 filings to go public in 2000, more than
      half are technology firms.

Far More Volatile

Behind the big gains for the year -- and for the past several decades -- is a
heightened volatility that often challenges investors to check their appetite
for risk. Internet stocks, for example, lost momentum in the spring and some of
the hottest performers came down as much as 50%. But the sector surged again
late in the summer. In fact, more than half of the Nasdaq's strong gains came in
the last quarter of the year.

Overall volatility for the Nasdaq set a record in 1999: The index fluctuated at
least 2% on more than half of the trading days of the year -- ten times the
number of days that saw that dimension of volatility in the first half of the
decade.

But Not Unprecedented

Market observers with a sense of the past point out that this is not the first
time one sector has dominated the U.S. stock market -- and the economy. To some,
the run-up is reminiscent of the high-flying days of railroad stocks in the
1920s or utility stocks in the 1950s. However, the closest comparison in recent
memory is with the energy boom in the 1970s. In the years following a global
energy crisis, the price of crude oil shot up to more than $30 a barrel and the
market capitalization of companies such as Exxon Mobil and Atlantic Richfield
swelled. "A lot of people thought that if oil could command $30/barrel, why not
$50?" says Wilson.

The energy sector, which accounted for just under 14% of the S&P 500 in 1978,
shot past 27% where it peaked in mid-1980 before falling to around 12% in 1983.
(Today energy accounts for 4.8% of the S&P 500.)

Technology Ahead

Does that mean technology is due for a fall? "In the near term, anything can
happen," says Wilson. "Technology has had a spectacular run, and we have
weighted the exposure of State Street Research Investment Trust to match the
market." Wilson sees the possibility of industry consolidation, which could
create volatility for the sector. That said, Wilson sees many opportunities
ahead. "Technology's impact on the economy is still in its infancy. We think
some fabulous blue chip companies are destined to emerge from this cycle. We
continue to look for companies with the potential for strong earnings growth,
who can control their own destinies." This is a better strategy than trying to
predict the market, says Wilson -- and good advice for individual investors, as
well.

A Closer Look [GRAPHIC]

Technology -
What Is It?

[GRAPHIC]

Headlines are full of stories about Internet and wireless start-ups, but there's
a lot more to this sector than these leading edge technologies. More than half
the revenues attributed to the broad sector known as technology comes from
companies that make the essential component for electronic circuitry called
semiconductors. Some of the most important technology companies make switches,
routers, and fiber optic cables that facilitate the distribution of data.
Biotechnology marries technology, pharmaceuticals and health care into a segment
of the market that could alter life expectancy the way computers and software
have boosted productivity.

A Repeat Performance

In a very real sense, technology has been the leading market sector during most
periods of rapid change. The railroads? Sure, they were a means of
transportation, but technology made them possible. Automobiles? Same thing. Even
the proliferation of chemicals that introduced new materials into our way of
life -- plastics, laminates, and synthetic fibers, to name a few -- are ours,
thanks to technology.

What's changed most over the decades, however, is the speed at which old
technologies are replaced by new ones. Today, it is the Internet. But tomorrow,
who knows? For investors, that is both the excitement and the challenge.

Performance in Perspective Management's Discussion of Fund Performance Part 2

                   Performance Figures as of December 31, 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 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.

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

Business structure

State Street Research Investment Trust 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 Master Investment 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 long-term growth of capital and secondarily, long-term
growth of income. In managing its portfolio, the fund generally attempts to
identify the industries that over the long term will grow faster than the
economy as a whole.

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. The fund will receive cash or securities as collateral in the
amount equal to at least 100% of the current market value of any loaned
securities plus accrued interest. 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 has
elected to be exempt from taxes under Subchapter M of the Internal Revenue Code,
in part because it makes distributions as described above.

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 text and notes are an integral part of the financial statements.

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

To the Trustees of State Street Research
Master Investment Trust and the Shareholders of
State Street Research Investment Trust

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 Investment Trust (a
series of State Street Research Master Investment Trust, hereafter referred to
as the "Trust") at December 31, 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 December 31, 1999 by
correspondence with the custodian and brokers, provide a reasonable basis for
the opinion expressed above.
