INVESTMENT UPDATE
- --------------------------------------------------------------------------------

INVESTMENT ENVIRONMENT

The Economy

[bullet] The last quarter of 1997 and the first quarter of 1998 were periods of
         solid economic growth, marked by low inflation and strong investment
         returns. Unemployment and interest rates remain low, and consumer
         confidence continues at near-record highs.

[bullet] Favorable economic factors have stimulated a boom in the housing
         market and stronger-than-expected retail sales.

[bullet] An economic crisis in Southeast Asia raised concerns about the
         potential impact on U.S. exports and profits at multinational
         companies. However, the effects have yet to be felt on American
         companies.

The Markets

[bullet] The S&P 500, a broad measure of common stock performance, gained
         17.21% for the six-month period.(1) Small stocks were strong at the
         beginning of the period, then gave back some of their gains as turmoil
         in Southeast Asia led a retreat to large-capitalization brand-name
         companies. Small stocks picked up again in March, the final month of
         the reporting period.

[bullet] Bonds gained momentum at the beginning of the six-month period, as
         long-term interest rates plunged below 6.0%, then delivered modest
         gains in the second half. High-yield bonds were among the quarter's
         strongest performers. Mortgage bonds held up well, despite concerns
         that refinancing could become a negative factor in the period ahead.

THE FUND

Over the past six months

[bullet] For the six months ended March 31, 1998, Class A shares of Aurora Fund
         returned +6.40% (does not reflect sales charge.)(2) The Fund lagged the
         Russell 2000 Value Index, which gained 10.17% for the period, but led
         the average small-company fund, which gained 5.32% according to Lipper
         Analytical Services.

[bullet] The Fund's investments in energy companies, especially those in the
         oil service segment, were a drag on performance.

[bullet] Investments in telecommunications and financial services stocks
         performed well. Demand for new products and expanded service remained
         high among telecommunications equipment companies. Stable interest
         rates, merger activity and strong investment markets helped financial
         companies.

Current strategy

[bullet] The manager continues to search for companies that sell at reasonable
         valuations and offer more than one opportunity for improving
         prospects.

March 31, 1998

(1)The Standard & Poor's 500 Composite Index (S&P 500) is a market-value
weighted index composed of 500 widely held common stocks. The Russell 2000 Value
Index is a weighted index comprised of the 2000 smallest stocks within the
Russell 3000 (a weighted index of the 3000 largest capitalized U.S. companies).
The indices are unmanaged and do not take transaction charges into account.
Direct investment in the indices is not possible; results are for illustrative
purposes only.

(2)+5.98% for Class B shares; +6.03% for Class C shares; +6.51% for Class S
shares.

(3)All returns represent past performance, which is no guarantee of future
results. The investment return and principal value of an investment made in the
Fund will fluctuate, and shares, when redeemed, may be worth more or less than
their original cost. All returns assume reinvestment of capital gain
distributions and income dividends. "S" shares, offered without a sales charge,
are available only through certain employee benefit plans and special programs.

(4)Performance reflects maximum 4.5% "A" share front-end sales charge or 5% "B"
share or 1% "C" share contingent deferred, sales charges, where applicable.

(5)Before November 1, 1997, Class C shares were designated Class D, and Class S
shares were designated Class C.

Because the Fund invests in special situation companies, an investment in the
Fund may involve greater-than-average risk and above average price fluctuation.
Small-company stocks are more volatile than large-company stocks.

Please note that the discussion throughout this shareholder report is dated as
indicated and, because of possible changes in viewpoint, data and transactions,
should not be relied upon as being current thereafter.

NOTES TO UNAUDITED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
March 31, 1998

Note 1

State Street Research Aurora Fund (the "Fund") is a series of State Street
Research Capital Trust (the "Trust"), which is a Massachusetts business trust
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Trust was organized in
November, 1988 as a successor to State Street Capital Fund, Inc., a
Massachusetts corporation. The Trust consists presently of three separate
funds: State Street Research Aurora Fund, State Street Research Emerging Growth
Fund and State Street Research Capital Fund.

The investment objective of the Fund is to provide high total return consisting
principally of capital appreciation. In seeking to achieve its investment
objective, the Fund invests primarily in the equity securities of small
capitalization companies which are trading at prices believed to be below the
true values of such securities.

The Fund is authorized to issue four classes of shares. Effective November 5,
1997, the Fund discontinued offering all four classes of shares. Before
November 1, 1997, Class C shares were designated Class D and Class S shares
were designated Class C. Class A share are subject to an initial sales charge
of up to 4.50% and pay an annual service fee equal to 0.25% of average daily
net assets. Class B shares are subject to a contingent deferred sales charge on
certain redemptions made within five years of purchase and pay annual
distribution and service fees of 1.00%. Class B shares automatically convert
into Class A shares (which pay lower ongoing expenses) at the end of the eight
years after the issuance of the Class B shares. Class C shares are subject to a
contingent deferred sales charge of 1.00% on any shares redeemed within one
year of their purchase. Class C shares also pay annual distribution and service
fees of 1.00%. Class S shares are only offered through certain retirement
accounts, advisory accounts of State Street Research & Management Company (the
"Adviser"), an indirect wholly owned subsidiary of Metropolitan Life Insurance
Company ("Metropolitan"), and special programs. No sales charge is imposed at
the time of purchase or redemption of Class S shares. Class S shares do not pay
any distribution or service fees. The Fund's expenses are borne pro rata by
each class, except that each class bears expenses, and has exclusive voting
rights with respect to provisions of the Plan of Distribution, related
specifically to that class. The Trustees declared separate dividends on each
class of shares.

The following significant policies are consistently followed by the Fund in
preparing its financial statements, and such policies are in conformity with
generally accepted accounting principles for investment companies.

A. Investments in Securities

Values for listed securities represent the last sale on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("NASDAQ") system

The accompanying notes are an integral part of the financial statements.

are valued at the closing price supplied through such system. In the absence of
recorded sales and for those over-the-counter securities not quoted on the
NASDAQ system, valuations are at the mean of the closing bid and asked
quotations, except for certain securities that may be restricted as to public
resale, which are valued in accordance with methods adopted by the Trustees.
Securities transactions are accounted for on the trade date (date the order to
buy or sell is executed), and dividends declared but not received are accrued
on the ex-dividend date. Interest income is determined on the accrual basis.
Realized gains and losses from security transactions are reported on the basis
of identified cost of securities delivered for both financial reporting and
Federal income tax purposes.

B. Federal Income Taxes

No provision for Federal income taxes is necessary since the Fund intends to
qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains, if
any, within the prescribed time period.

C. Dividends

Dividends from net investment income, if any, are declared and paid or
reinvested annually. Net realized capital gains, if any, are distributed
annually, unless additional distributions are required for compliance with
applicable tax regulations.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.

D. Deferred Organization Costs

Certain costs incurred in the organization and registration of the Fund were
capitalized and are being amortized under the straight-line method over a
period of five years.

E. Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.

F. Securities Lending

The Fund may seek additional income by lending portfolio securities to
qualified institutions. The Fund will receive cash or securities as collateral
in an 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 and
losses. If the borrower fails to return the securities and the value of the
collateral has declined during the term of the loan, the Fund will bear the
loss. At March 31, 1998, the value of the securities loaned and the value of
collateral were $26,576,850 and $26,915,230, respectively. During the six
months ended March 31, 1998, income from securities lending amounted to
$282,651 and is included in interest income.

Note 2

The Trust and the Adviser have entered into an agreement under which the
Adviser earns monthly fees at an annual rate of 0.85% of the Fund's average
daily net assets. In consideration of these fees, the Adviser furnishes the
Fund with management, investment advisory, statistical and research facilities
and services. The Adviser also pays all salaries, rent and certain other
expenses of management. During the six months ended March 31, 1998, the fees
pursuant to such agreement amounted to $2,517,266.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), and indirect wholly owned subsidiary of Metropolitan, provides
certain shareholder services to the Fund such as responding  to inquiries and
instructions from investors with respect to the purchase and redemption of
shares of the Fund. During the six months ended March 31, 1998, the amount of
such expenses was $184,052.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$21,861 during the six months ended March 31, 1998.

Note 3

For the six months ended March 31, 1998, exclusive of short-term investments
and U.S. Government obligations, purchases and sales of securities aggregated
$339,846,149 and $109,863,766, respectively.

Note 4

The Trust has adopted a Plan of Distribution Pursuant to Rule 12b-1 (the
"Plan") under the Investment Company Act of 1940. Under the Plan, the Fund pays
annual service fees to the Distributor at a rate of 0.25% of average daily net
assets for Class A, Class B and Class C shares. In addition, the Fund pays
annual distribution fees of 0.75% of average daily net assets for Class B and
Class C shares. The Distributor uses such payments for personal services and/or
the maintenance or servicing of shareholder accounts, to reimburse securities
dealers for distribution and marketing services, to furnish ongoing assistance
to investors and to defray a portion of its distribution and marketing
expenses. For the six months ended March 31, 1998, fees pursuant to such plan
amounted to $247,146, $1,503,864, and $445,498 for Class A, Class B and Class C
shares, respectively.

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $167,760 and $197,594, respectively, on sales of Class A shares of
the Fund during the six months ended March 31, 1998, and that MetLife
Securities, Inc. earned commissions aggregating $622,639 on sales of Class B
shares, and that the Distributor collected contingent deferred sales charges
aggregating $186,725 and $20,663 on redemptions of Class B and Class C shares,
respectively, during the same period.

STATE STREET RESEARCH CAPITAL FUND
- --------------------------------------------------------------------------------
INVESTMENT UPDATE
- --------------------------------------------------------------------------------

INVESTMENT ENVIRONMENT

The Economy

[bullet] The last quarter of 1997 and the first quarter of 1998 were periods of
         solid economic growth, marked by low inflation and strong investment
         returns. Unemployment and interest rates remain low, and consumer
         confidence continues at near-record highs.

[bullet] Favorable economic factors have stimulated a boom in the housing
         market and stronger-than-expected retail sales. Lower energy costs
         helped keep inflation in check.

[bullet] An economic crisis in Southeast Asia raised concerns about the
         potential impact on U.S. exports and profits at multinational
         companies. However, the effects have been modest so far on most
         American companies.

The Markets

[bullet] The S&P 500, a broad measure of common stock performance, gained
         17.21% for the six-month period(1). Small stocks were strong at the
         beginning of the period, then gave back some of their gains as turmoil
         in Southeast Asia led a retreat to large-capitalization brand-name
         companies. Small stocks picked up again in the final month of the
         period.

[bullet] Bonds gained momentum at the beginning of the six-month period, as
         long-term interest rates plunged below 6.0%, then delivered modest
         gains in the second half. High-yield bonds were among the quarter's
         strongest performers. Mortgage bonds held up well, despite concerns
         that refinancing could become a negative factor in the period ahead.

THE FUND

Over the past six months

[bullet] For the six months ended March 31, 1998, Class A shares of Capital Fund
         returned +5.97% [does not reflect sales charge.](2) The Fund
         underperformed other capital appreciation funds, which averaged a gain
         of 7.19% for the period, according to Lipper Analytical Services.

[bullet] Although the Fund lagged its peer group for the period, it delivered
         solid returns in the last three months of the period and was among the
         strongest of all capital appreciation funds.

[bullet] The Fund's investments in consumer and media stocks helped boost
         performance as many of these companies reported higher earnings.

[bullet] The Fund's exposure to technology was a drag on performance as these
         stocks were brought down with the turmoil in Asia last year.

Current Strategy

[bullet] New manager Richard Jodka cut back on the Fund's investment in
         volatile technology stocks and placed more emphasis on mid-sized
         consumer and health care stocks with above-average growth potential.

[bullet] Reduced turnover, lower volatility and an emphasis on valuation are
         all part of the manager's plans for the Fund.

March 31, 1998

(1) The Standard & Poor's 500 Composite Index (S&P 500) is a market-value
weighted index composed of 500 widely held common stocks. The index is unmanaged
and does not take sales charges into account. Direct investment in the index is
not possible; results are for illustrative purposes only.

(2) +5.48% for Class B shares; +5.54% for Class C shares; +6.09% for Class S
shares.

(3) All returns represent past performance, which is no guarantee of future
results. The investment return and principal value of an investment made in the
Fund will fluctuate and shares, when redeemed, may be worth more or less than
their original cost. All returns assume reinvestment of capital gain
distributions and income dividends. Performance for a class may include periods
prior to the adoption of class designations in 1993, which resulted in new or
increased 12b-1 fees of up to 1% per class thereafter and which will reduce
subsequent performance. "S" shares, offered without a sales charge, are
available through certain employee benefit plans and special programs.

(4) Performance reflects maximum 4.5% "A" share front-end sales charge or 5% "B"
share or 1% "C" share contingent deferred sales charges, where applicable.

(5) Before November 1, 1997, Class C shares were designated Class D, and Class S
shares were designated Class C.

Because the Fund invests in emerging growth and special situation companies, an
investment in the Fund may involve greater-than-average risk and above-average
price fluctuation. Small-company stocks are more volatile than large-company
stocks.

Please note that the discussion throughout this shareholder report is dated as
indicated and, because of possible changes in viewpoint, data and transactions,
should not be relied upon as being current thereafter.

STATE STREET RESEARCH CAPITAL FUND
- --------------------------------------------------------------------------------
NOTES TO UNAUDITED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
March 31, 1998

Note 1

State Street Research Capital Fund (the "Fund"), is a series of State Street
Research Capital Trust (the "Trust"), which is a Massachusetts business trust
registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Trust was organized in
November, 1988 as a successor to State Street Capital Fund, Inc., a
Massachusetts corporation. The Trust consists presently of three separate
funds: State Street Research Capital Fund, State Street Research Emerging
Growth Fund and State Street Research Aurora Fund.

The investment objective of the Fund is to seek 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.

The Fund offers four classes of shares. Before November 1, 1997, Class C shares
were designated Class D and Class S shares were designated Class C. Class A
shares are subject to an initial sales charge of up to 4.50% and pay an annual
service fee equal to 0.25% of average daily net assets. Class B shares are
subject to a contingent deferred sales charge on certain redemptions made
within five years of purchase and pay annual distribution and service fees of
1.00%. Class B shares automatically convert into Class A shares (which pay
lower ongoing expenses) at the end of eight years after the issuance of the
Class B shares. Class C shares are subject to a contingent deferred sales
charge of 1.00% on any shares redeemed within one year of their purchase. Class
C shares also pay annual distribution and service fees of 1.00%. Class S shares
are only offered through certain retirement accounts, advisory accounts of
State Street Research & Management Company (the "Adviser"), an indirect wholly
owned subsidiary of Metropolitan Life Insurance Company ("Metropolitan"), and
special programs. No sales charge is imposed at the time of purchase or
redemption of Class S shares. Class S shares do not pay any distribution or
service fees. The Fund's expenses are borne pro-rata by each class, except that
each class bears expenses, and has exclusive voting rights with respect to
provisions of the Plan of Distribution, related specifically to that class. The
Trustees declare separate dividends on each class of shares.

The following significant policies are consistently followed by the Fund in
preparing its financial statements, and such policies are in conformity with
generally accepted accounting principles for investment companies.

A. Investments in Securities

Values for listed securities represent the last sale on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("NASDAQ") system are valued at the closing price
supplied through such system. In the absence of recorded sales and for those
over-the-counter securities not quoted on the NASDAQ system, valuations are at
the mean of the closing bid and asked quotations, except for certain securities
that may be restricted as to public resale, which are valued in accordance with
methods adopted by the Trustees. Security transactions are accounted for on the
trade date (date the order to buy or sell is executed), and dividends declared
but not received are accrued on the ex-dividend date. Interest income is
determined on the accrual basis. Realized gains and losses from security
transactions are reported on the basis of identified cost of securities
delivered for both financial reporting and Federal income tax purposes.

B. Federal Income Taxes

No provision for Federal income taxes is necessary since the Fund has elected
to qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains,
within the prescribed time periods.

C. Dividends

Dividends from net investment income, if any, are declared and paid or
reinvested annually. Net realized capital gains, if any, are distributed
annually, unless additional distributions are required for compliance with
applicable tax regulations.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.

D. Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.

E. Securities Lending

The Fund may seek additional income by lending portfolio securities to
qualified institutions. The Fund will receive cash or securities as collateral
in an 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 and
losses. If the borrower fails to return the securities and the value of the
collateral has declined during the term of the loan, the Fund will bear the
loss. At March 31, 1998, the value of the securities loaned and the value of
collateral were $63,509,625 and $67,676,074, respectively. During the six
months ended March 31, 1998, income from securities lending amounted to
$102,452 and is included in interest income.

Note 2

The Trust and the Adviser have entered into an agreement under which the
Adviser earns monthly fees at an annual rate of 0.75% of the Fund's average
daily net assets. In consideration of these fees, the Adviser furnishes the
Fund with management, investment advisory, statistical and research facilities
and services. The Adviser also pays all salaries, rent and certain other
expenses of management. During the six months ended March 31, 1998, the fees
pursuant to such agreement amounted to $4,432,844.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), an indirect wholly owned subsidiary of Metropolitan, provides
certain shareholder services to the Fund such as responding to inquiries and

instructions from investors with respect to the purchase and redemption of
shares of the Fund. In addition, Metropolitan receives a fee for maintenance of
the accounts of certain shareholders who are participants in sponsored
arrangements, employee benefit plans and similar programs or plans, through or
under which shares of the Fund may be purchased. During the six months ended
March 31, 1998, the amount of such expenses was $393,319.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$19,605 during the six months ended March 31, 1998.

Note 3

For the six months ended March 31, 1998, exclusive of short-term investments
and U.S. Government obligations, purchases and sales of securities aggregated
$443,261,480 and $655,475,332, respectively.

Note 4

The Trust has adopted a Plan of Distribution pursuant to Rule 12b-1 (the
"Plan") under the Investment Company Act of 1940. Under the Plan, the Fund pays
annual service fees to the Distributor at a rate of 0.25% of average daily net
assets for Class A, Class B and Class C shares. In addition, the Fund pays
annual distribution fees of 0.75% of average daily net assets for Class B and
Class C shares. The Distributor uses such payments for personal services and/or
the maintenance or servicing of shareholder accounts, to reimburse securities
dealers for distribution and marketing services, to furnish ongoing assistance
to investors and to defray a portion of its distribution and marketing
expenses. For the six months ended March 31, 1998, fees pursuant to such plan
amounted to $528,665, $2,489,211 and $467,725 for Class A, Class B and Class C
shares, respectively.

The Fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of Metropolitan, earned initial sales charges
aggregating $45,107 and $283,196, respectively, on sales of Class A shares of
the Fund during the six months ended March 31, 1998, and that MetLife
Securities, Inc. earned commissions aggregating $483,546 on sales of Class B
shares, and that the Distributor collected contingent deferred sales charges of
$730,572 and $11,026 on redemptions of Class B and Class C shares,
respectively, during the same period.

Note 5

The Trustees have the authority to issue an unlimited number of shares of
beneficial interest, $.001 par value per share.

STATE STREET RESEARCH EMERGING GROWTH FUND
- --------------------------------------------------------------------------------
INVESTMENT UPDATE
- --------------------------------------------------------------------------------

INVESTMENT ENVIRONMENT

The Economy

[bullet] The last quarter of 1997 and the first quarter of 1998 were periods of
         solid economic growth, marked by low inflation and strong investment
         returns. Unemployment and interest rates remain low, and consumer
         confidence continues at near-record highs.

[bullet] Favorable economic factors have stimulated a boom in the housing
         market and stronger-than-expected retail sales.

[bullet] An economic crisis in Southeast Asia raised concerns about the
         potential impact on U.S. exports and profits at multinational
         companies. However, the effects have yet to be felt by American
         companies.

The Markets

[bullet] The S&P 500, a broad measure of common stock performance, gained
         17.21% for the six-month period.(1) Small stocks were strong at the
         beginning of the period, then gave back some of their gains as turmoil
         in Southeast Asia led a retreat to large-capitalization brand-name
         companies. Small stocks picked up again in March, the final month of
         the period.

[bullet] Bonds gained momentum at the beginning of the six-month period, as
         long-term interest rates plunged below 6.0%, then delivered modest
         gains in the second half. High-yield bonds were among the quarter's
         strongest performers. Mortgage bonds held up well, despite concerns
         that refinancing could become a negative factor in the period ahead.

THE FUND

Over the past six months

[bullet] For the six months ended March 31, 1998, Class A shares of Emerging
         Growth Fund returned 5.59% [does not reflect sales charge.](2) The Fund
         outperformed the Russell 2000 Growth Index, a common measure of small
         company growth stock performance, which gained 2.71% over the same
         period, and the Lipper Small Cap Fund Average, which was up 5.32%.

[bullet] Good stock selection among the consumer, financial, health care and
         technology sectors helped boost performance. Both the consumer and
         financial sectors offer growth potential at attractive valuations.
         Business prospects have improved for health care companies. And
         technology recovered from a sell-off during the fourth quarter of 1997.

[bullet] Declining oil prices hurt the Fund's investment in energy stocks.
         Current Strategy

[bullet] The manager added to the Fund's investment in technology and health
         care stocks.

[bullet] Because the small-cap sector, in general, is at or near a historical
         low in valuation relative to large-cap stocks, the Fund continues to
         seek opportunity among small-cap stocks with growth potential and
         attractive valuations.

March 31, 1998

(1)The Standard & Poor's 500 Composite Index (S&P 500) is a market-value
weighted index composed of 500 widely held common stocks. The index is unmanaged
and does not take sales charges into account. Direct investment in the index is
not possible; results are for illustrative purposes only.

(2) 5.15% for Class B shares; 5.16% for Class C shares; 5.73% for Class S
shares.

(3)All returns represent past performance, which is no guarantee of future
results. The investment return and principal value of an investment made in the
Fund will fluctuate and shares, when redeemed, may be worth more or less than
their original cost. All returns assume reinvestment of capital gain
distributions and income dividends. Performance for a class may include periods
prior to the adoption of class designations in 1994, which resulted in new or
increased 12b-1 fees of up to 1% per class thereafter and which will reduce
subsequent performance. "S" shares, offered without a sales charge, are
available through certain employee benefit plans and special programs.

(4)Performance reflects maximum 4.5% "A" share front-end sales charge or 5% "B"
share or 1% "C" share contingent deferred sales charges, where applicable.

(5) Before November 1, 1997, Class C shares were designated Class D, and Class S
shares were designated Class C.

Because the Fund invests in emerging growth and special situation companies, an
investment in the Fund may involve greater-than-average risk and above-average
price fluctuation. Small-company stocks are more volatile than large-company
stocks.

Please note that the discussion throughout this shareholder report is dated as
indicated and, because of possible changes in viewpoint, data and transactions,
should not be relied upon as being current thereafter.

Performance results for the Fund are increased by the voluntary reduction of
Fund fees and expenses; without subsidization, performance would have been
lower.

STATE STREET RESEARCH EMERGING GROWTH FUND
- --------------------------------------------------------------------------------
NOTES TO UNAUDITED FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------
March 31, 1998

Note 1

State Street Research Emerging Growth Fund (the "Fund"), is a series of State
Street Research Capital Trust (the "Trust"), which is a Massachusetts business
trust registered under the Investment Company Act of 1940, as amended, as a
diversified, open-end management investment company. The Trust was organized in
November, 1988 as a successor to State Street Capital Fund, Inc., a
Massachusetts corporation. The Trust consists presently of three separate
funds: State Street Research Emerging Growth Fund, State Street Research
Capital Fund and State Street Research Aurora Fund.

The investment objective of the Fund is 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.

The Fund offers four classes of shares. Before November 1, 1997, Class C shares
were designated Class D and Class S shares were designated Class C. Class A
shares are subject to an initial sales charge of up to 4.50% and pay an annual
service fee equal to 0.25% of average daily net assets. Class B shares are
subject to a contingent deferred sales charge on certain redemptions made
within five years of purchase and pay annual distribution and service fees of
1.00%. Class B shares automatically convert into Class A shares (which pay
lower ongoing expenses) at the end of eight years after the issuance of the
Class B shares. Class C shares are subject to a contingent deferred sales
charge of 1.00% on any shares redeemed within one year of their purchase. Class
C shares also pay annual distribution and service fees of 1.00%. Class S shares
are only offered through certain retirement accounts, advisory accounts of
State Street Research & Management Company (the "Adviser"), an indirect wholly
owned subsidiary of Metropolitan Life Insurance Company ("Metropolitan"), and
special programs. No sales charge is imposed at the time of purchase or
redemption of Class S shares. Class S shares do not pay any distribution or
service fees. The Fund's expenses are borne pro-rata by each class, except that
each class bears expenses, and has exclusive voting rights with respect to
provisions of the Plan of Distribution, related specifically to that class. The
Trustees declare separate dividends on each class of shares.

The following significant policies are consistently followed by the Fund in
preparing its financial statements, and such policies are in conformity with
generally accepted accounting principles for investment companies.

A. Investments in Securities

Values for listed securities represent the last sale on national securities
exchanges quoted prior to the close of the New York Stock Exchange.
Over-the-counter securities quoted on the National Association of Securities
Dealers Automated Quotation ("NASDAQ") system are valued at the closing price
supplied through such system. In the absence of recorded sales and for those
over-the-counter securities not quoted on the NASDAQ system, valuations are at
the mean of the closing bid and asked quotations, except for certain securities
that may be restricted as to public resale, which are valued in accordance with
methods adopted by the Trustees. Security transactions are accounted for on the
trade date (date the order to buy or sell is executed), and dividends declared
but not received are accrued on the ex-dividend date. Interest income is
determined on the accrual basis. Realized gains and losses from security
transactions are reported on the basis of identified cost of securities
delivered for both financial reporting and Federal income tax purposes.

B. Federal Income Taxes

No provision for Federal income taxes is necessary since the Fund intends to
qualify under Subchapter M of the Internal Revenue Code and its policy is to
distribute all of its taxable income, including net realized capital gains, if
any, within the prescribed time periods.

C. Dividends

Dividends from net investment income, if any, are declared and paid or
reinvested annually. Net realized capital gains, if any, are distributed
annually, unless additional distributions are required for compliance with
applicable tax regulations.

Income dividends and capital gain distributions are determined in accordance
with Federal income tax regulations which may differ from generally accepted
accounting principles.

D. Deferred Organization Costs

Certain costs incurred in the organization and registration of the Fund were
capitalized and are being amortized under the straight-line method over a
period of five years.

E. Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of income and expenses during the reporting period. Actual
results could differ from those estimates.

F. Securities Lending

The Fund may seek additional income by lending portfolio securities to
qualified institutions. The Fund will receive cash or securities as collateral
in an 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 and
losses. If the borrower fails to return the securities and the value of the
collateral has declined during the term of the loan, the Fund will bear the
loss. At March 31, 1998, the value of the securities loaned and the value of
collateral were $14,517,406 and $14,620,424, respectively. During the six
months ended March 31, 1998, income from securities lending amounted to $41,978
and is included in interest income.

Note 2

The Trust and the Adviser have entered into an agreement under which the
Adviser earns monthly fees equal to 0.75% of the Fund's average daily net
assets. In consideration of these fees, the Adviser furnishes the Fund with
management, investment advisory, statistical and research facilities and
services. The Adviser also pays all salaries, rent and certain other expenses
of management. During the six months ended March 31, 1998, the fees pursuant to
such agreement amounted to $359,237.

This report is prepared for the general information of current shareholders.

When used in the general solicitation of investors, this report must be
accompanied by a current State Street Research Emerging Growth Fund prospectus.
When used after June 30, 1998, this report must be accompanied by a current
Quarterly Performance Update.

Portfolio changes should not be considered recommendations for action by
individual investors.

The Dalbar awards recognize quality shareholder service and should not be
considered a rating of fund performance. The survey included mutual fund
