 FROM THE CHAIRMAN
          State Street Research

Optimism in the Economy

The pace of U.S. economic growth was robust over the past 12 months as the
economy advanced on all fronts. Gross domestic product (GDP) growth, a common
measure of economic growth, averaged just short of 4.0% for the period, solidly
above the economy's long-term trend rate of 3.0%. Our analysts expect the
economy to grow between 3.5% and 4.0% for the remainder of 2004 and into 2005.

Consumers continued to play a key role in the economy. Spending on retail goods,
autos and housing remained generally strong throughout the period. Retail sales
slowed during the summer months of 2004 as a result of higher energy prices and
weather-related events. But the pace of consumer spending picked up again in
September, as did consumer confidence, which see-sawed along with the outlook
for the labor market throughout the period.

The number of new jobs continued to fall short of expectations. In the spring,
more than one million new jobs were added to the economy. But job growth was
disappointing again during the summer months. The economy has yet to replace all
the jobs lost in the downturn of 2000-2001.

A pick-up in business spending was the bright spot in the economy. Industrial
production moved steadily higher, as did manufacturing capacity utilization.
Outlays for new equipment and construction enjoyed double-digit growth in the
second half of the period. Strong spending by business helped offset some of the
slowdown in consumer spending.

Stocks Stumble, Bonds Edge Higher

The U.S. stock market began the period on a strong note. However, the
double-digit gains it achieved over the twelve months covered by this report
were accumulated early in the period and the broad stock market indexes have
been essentially flat in 2004. By contrast, the bond market has held up in the
face of three increases in the Federal funds rate (a key short-term interest
rate) that occurred late in the period. The yield on the 10-year benchmark U.S.
Treasury ended the period only slightly higher than where it began, and bond
prices moved higher across all sectors.

Investing Despite Uncertainty

By all accounts, news on the economy and the markets has been overshadowed over
the past year by external events. As a result, many investors have remained on
the sidelines. With so much uncertainty, it may feel safer to wait out the
storm. Yet, it can be even more risky to try to time your entrances and exits as
the markets move through their natural cycles. If you're feeling uncertain about
your financial strategy, talk to your financial professional. With the advice
and guidance of a financial professional, you can keep your financial goals on
track.

Sincerely,

/s/ Richard S. Davis

PERFORMANCE

         Discussion as of September 30, 2004

How State Street Research Mid-Cap Growth Fund Performed State Street Research
Mid-Cap Growth Fund (Class A shares, without sales charge) returned 11.59% for
the 12-month period ended September 30, 2004. The fund underperformed the
Russell Midcap[RegTM] Growth Index, which returned 13.68% over the same period.
However, the fund outperformed the Lipper Mid-Cap Growth Funds Average, which
was 10.42% for the period.

- --------------------------------------------------------------------------------

Reasons for the Fund's Performance

Although the fund lagged its benchmark during the year, it posted attractive
gains. Its strong absolute return was the result of stock selection in the autos
& transportation, energy and health care sectors. An emphasis on the
top-performing energy sector also helped boost returns. The fund's shortfall
relative to its benchmark was the result of weak stock selection in the
technology, producer durables and materials & processing sectors.

Within the automobiles & transportation sector, labor costs, rising fuel prices
and increasing competition continued to weigh on the airline industry. In
energy, our holdings in coal and crude oil producers Consol Energy and EOG
Resources benefited from rising prices. Both companies' stock prices are highly
dependent on the underlying commodity prices. Within the technology sector,
American Power Conversion and Cypress Semiconductor were among the largest
detractors from the fund's return during the period.

Looking Ahead

We believe that continued signs of economic strength, an accommodative Federal
Reserve Board policy and the resolution of the uncertainty surrounding the
presidential election could provide the catalysts for positive momentum in the
stock market going forward. In this environment, we believe that stock selection
is likely to drive returns. We will continue to focus our efforts on fundamental
research and bottom-up stock selection.

A Word about Risk

The major risks of stock investing include sudden and unpredictable drops in
value and period of lackluster performance. Growth stocks of any size company
often have an above-average sensitivity to market fluctuations as their market
prices tend to reflect future expectations. At times when it appears that these
expectations may not be met, growth stock prices typically fall. Mid-cap
companies entail greater risk and are usually more volatile than larger
companies. Growth stocks can be volatile, as they usually reinvest a high
proportion of their earnings in their own business and lack the dividends
associated with value stocks.

PERFORMANCE
- ------------------
         Discussion as of September 30, 2004

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is not a guarantee of future results, long-term returns
can serve as an important context for evaluating recent performance. There are
three ways of measuring long-term performance: cumulative total returns, average
annual total 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

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.

Average Annual Total Return

Represents the rate you would have had to earn during each year of a given time
period in order to end up with the fund's actual cumulative return for those
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 10 Years

Similar to cumulative total return, but uses dollars rather than percentages,
and assumes that the lump sum you invested was $10,000 (less the applicable
maximum sales charge, if any) and compares fund performance to the performance
of a market index.

Cumulative and Average Annual Total Return at maximum applicable sales charge
reflect a maximum 5.75% Class A share front-end sales charge, or 5% Class B(1)
or Class B share or 1% Class C share contingent deferred sales charge, where
applicable. Performance for Class B(1) shares reflects Class B share performance
through December 31, 1998, and Class B(1) performance thereafter. If the returns
for Class B(1) shares had reflected their current service/distribution [Rule
12b-1] fees for the entire period, returns would have been lower. Class S
shares, offered without sales charge, are available through certain retirement
plans and special programs.

The Russell Midcap Growth Index contains those stocks within the complete
Russell Midcap Index (800 of the smallest securities in the Russell 1000 Index)
that show above-average growth. The index is unmanaged and does not take
transaction charges into consideration. It is not possible to invest directly in
an index.

About Your Fund Expenses

As a fund shareholder, you incur two types of costs: (1) Transaction costs,
which include sales charges, and (2) ongoing expenses, which include management
fees, service/distribution fees (12b-1) and "other" expenses. The examples below
illustrate the ongoing cost in dollars of investing in the fund and allow you to
compare these costs with the expenses of other funds. The examples are based on
a $1,000 investment at the beginning of the period and held for the entire
period from March 31, 2004, to September 30, 2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number shown for your
fund under the column "Expenses Paid during the Period."

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending account balance and expenses paid during the period.
To compare your fund's ongoing expenses with those of other funds, simply
compare this 5% hypothetical example with the 5% hypothetical examples shown in
the shareholder reports of other funds.

 * Expenses are equal to the fund's annualized expense ratio multiplied by the
   average account value over the period, multiplied by the number of days in
   the period and then divided by the number of days in the year.

Please note that the expenses shown in the table are meant to highlight and help
you compare ongoing costs only and do not reflect transactional expenses such as
sales charges, which would result in higher total expenses. It should also be
noted that, for certain funds, expenses have been subsidized or reduced through
expense offset arrangements, which reduces costs for shareholders. Generally,
the fund expects that the expense subsidy or expense offset arrangement will
continue although there is no guarantee that it will. Please see the fund's
prospectus for more information.

Notes to Financial Statements
- --------------------------------------------------------------------------------
September 30, 2004

Note 1
State Street Research Mid-Cap Growth Fund is a series of State Street Research
Capital Trust (the "Trust"), which is a Massachusetts business trust and is
registered under the Investment Company Act of 1940, as amended, as an open-end
management investment company.

The investment objective of the fund is to provide long-term growth of capital.
Under normal market conditions, the fund invests at least 80% of its net assets
in mid-cap stocks. These may include common and preferred stocks, convertible
securities and warrants.

The fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 5.75% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) shares pay annual service and
distribution fees equal to 1.00% of average daily net assets and automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) and Class B shares are subject to a contingent deferred
sales charge on certain redemptions made within six years and five years of
purchase, respectively. Class B shares are offered only to current shareholders
through reinvestment of dividends and distributions or through exchanges from
existing Class B accounts of State Street Research funds and also automatically
convert to Class A shares at the end of eight years. Currently, the annual
service and distribution fees paid by Class B Shares have been voluntarily
reduced to 0.00%. 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 service and distribution fees equal to 1.00% of average
daily net assets. Class S shares are only offered through certain retirement
accounts, advisory accounts of State Street Research & Management Company (the
"Adviser"), an investment management subsidiary of MetLife, Inc. ("MetLife"),
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 service or
distribution fees. The fund's expenses are borne prorata by each class, except
that each class bears expenses, and has exclusive voting rights with respect to
provisions of the plans of distribution, related specifically to that class.
Income, expenses (other than service and distribution fees), and realized and
unrealized gains on losses on investments are allocated to each class of shares
based on its relative net assets. The Trustees declare separate dividends on
each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation

Values for listed equity securities reflect final sales 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 closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Short-term securities maturing within sixty days are valued at
amortized cost. Other securities, if any, are valued at their fair value as
determined in good faith under consistently applied procedures established by
and under the supervision of the Trustees. In the event that the market
quotations for a portfolio instrument are not deemed to be readily available,
the Investment Adviser's Valuation Committee determines the fair value for such
portfolio instrument. The fair value of any such portfolio instruments are
determined based upon a consideration of all available facts and information.
The fair valuation of a restricted portfolio instrument reflects the inherent
worth of the portfolio instrument, without regard to the restrictive feature,
adjusted for any diminution in value resulting from the restrictive feature. The
Investment Adviser and the Custodian also monitor domestic and foreign markets
and news information for any developing events that may have an impact on the
valuation of portfolio instruments. Such monitoring includes general market news
and financial market information sources currently

utilized in making investment decisions, trading and investment personnel
located abroad, foreign regional brokers, and /or foreign custodians. The value
assigned to these securities is based upon available information at the time,
and does not necessarily represent the amount which might ultimately realized
upon sale.

B. Security Transactions

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered.

As part of the custodian contract between the custodian bank and the fund, the
custodian bank has a lien on the securities of the fund to the extent permitted
by the fund's investment restriction to cover any advances made by the custodian
bank for the settlement of securities purchased by the fund. At September 30,
2004 the payable to the custodian bank of $327 represents the amount due for
cash advance for the settlement of the security purchased.

C. Net Investment Income

Net investment income is determined daily and consists of interest and dividends
accrued and discount earned, less the estimated daily expenses of the fund.
Interest income is accrued daily as earned. Dividend income is accrued on the
ex-dividend date. The fund is charged for expenses directly attributable to it,
while indirect expenses are allocated among all funds in the Trust.

D. Dividends

Dividends from net investment income 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 gains distributions are determined in accordance
with federal income tax regulations which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
due to differing treatments for wash sale deferrals.

E. Federal Income Taxes

No provision for federal income taxes is necessary because 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.

At September 30, 2004, the fund had a capital loss carryforward of $299,268,696
available, to the extent provided in regulations, to offset future capital
gains, if any, of which $212,041,374, and $87,227,324 expire on September 30,
2010 and 2011, respectively.

To the extent book/tax differences are permanent in nature, such amounts are
reclassified within the capital accounts based on federal tax basis treatment.
The fund reclassified for book purposes amounts arising from permanent book/tax
differences primarily relating to net operating losses not utilized. At
September 30, 2004, the components of distributable earnings on a tax basis
differ from the amounts reflected in the Statement of Assets and Liabilities by
temporary book/tax differences largely arising from wash sales and capital loss
carryforwards. At September 30, 2004, the tax basis distributable earnings were
$0 in undistributed ordinary income, $0 in undistributed short-term capital
gains and $0 in undistributed long-term gains.

F. Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America 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 these estimates.

G. 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 September
30, 2004, the value of the securities loaned and the value of collateral were
$45,267,637 and $46,290,672 (consisting entirely of cash collateral invested in
State Street Navigator Securities Lending Prime Portfolio), respectively. The
collateral was marked to market the next business day and made equal to at least
100% of the current market value of the loaned securities and accrued interest.
During the year ended September 30, 2004, income from securities lending
amounted to $96,355.

H. Options
The Fund may use options to hedge against changes in values of securities the
Portfolio owns or expects to purchase. Writing puts or buying calls tends to
increase the fund's exposure to the underlying instrument and writing calls or
buying puts tends to decrease the fund's exposure to the underlying instrument,
or hege other fund investments.

For options purchased to hedge the fund's investments, the potential risk to the
fund is that the change in value of options contracts may correspond to the
change in value of the hedged instruments. In addition, losses may arise from
changes in the value of the underlying instruments, if there is an illiquid
secondary market, or if the counter party is unable to perform. The maximum loss
for purchased options is limited to the premium initially paid for the option.
For options written by the fund, the maximum loss is not limited to the premium
initially received for the option.

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 first $500 million of
average net assets, 0.70% of the next $500 million, and 0.65% of any amount over
$1 billion of average 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 year ended September 30, 2004,
the fees pursuant to such agreement amounted to $2,805,522.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), 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, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the year ended September 30, 2004, the amount of such expenses allocated to the
fund was $491,746.

The fund has entered onto an arrangement with its custodian whereby credits
realized as a result of directed brokerage commissions were used to reduce a
portion of the fund's expenses. During the twelve months ended September 30,
2004 the fund's custodian fees were reduced by $1,281 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$21,924 during the year ended September 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the year ended September 30, 2004, the amount of such expenses was
$106,536.

On February 19, 2004, the Distributor entered into an agreement with the NASD
resolving all outstanding issues relating to an investigation by the NASD of the
Distributor's email retention practices and supervision of trading activity in
shares of the State Street Research funds. The Distributor, without admitting or
denying the allegations or the findings set forth in the agreement, and solely
for the purposes of the settlement, agreed to the entry of certain findings by
the NASD relating to the Distributor's compliance with document retention
requirements and the Distributor's supervision of enforcement of shareholder
exchange limitations set forth in the funds' prospectuses. The agreement
contains no allegations or findings of fraudulent conduct by the Distributor. As
part of the agreement the Distributor made a payment to the fund to compensate
the fund for losses relating to the exchange of fund shares beyond the annual
limit set forth in the fund's prospectus. The payment was allocated among the
fund's share classes as follows: $5,845 to Class A; $813 to Class B(1); $1,587
to Class B; $323 to Class C; and $958 to Class S. These amounts are

shown in the total amount of $9,526 as "Net increase from payment by affiliate"
in the Statement of Operations.

Note 3
For the year ended September 30, 2004, purchases and sales of securities,
exclusive of short-term obligations, aggregated $356,332,906, and $391,772,228,
respectively.

Note 4
The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, 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(1), Class B and Class C shares. In addition, the fund pays annual
distribution fees of 0.05% of average daily net assets for Class A shares. The
fund pays annual distribution fees of 0.75% of average daily net assets for
Class B(1) and Class C shares. Currently, the annual service and distribution
fees paid by Class B shares have been voluntarily reduced to 0.00%. The
Distributor uses such payments for personal services and/or the maintenance 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 year ended September
30, 2004, fees pursuant to such plans amounted to $669,777, $320,033 and
$126,457 for Class A, Class B(1) and Class C shares, respectively. For Class A,
Class B and Class C shares, the payments are intended to reimburse the
distributor for expenditures incurred under the plan, and any unused payments
are returnable to the fund. As of September 30, 2004, there were $2,427,848,
$14,985 and $1,771,015 for Class A, Class B, and Class C shares, respectively,
of unreimbursed distribution and shareholder servicing related expenses to be
carried forward to future plan years. For Class B(1) shares, the payments
compensate the distributor for services and expenditures incurred under the
plan, and none of the payments are returnable to the fund. During the year ended
September 30, 2004 the Distributor reimbursed a total of $270,857 to Class B
shares of the fund reflecting the estimated excess of payments received over
costs incurred under the plan. This amount is shown as "Reimbursement of
Distribution Fees" in the Statement of Operations.

The fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of MetLife, earned initial sales charges aggregating
$163,181 and $747,057, respectively, on sales of Class A shares of the fund
during the year ended September 30, 2004, and that MetLife Securities, Inc.
earned commissions aggregating $574,627 and $7,297 on sales of Class B(1) and
Class C shares, and the Distributor collected contingent deferred sales charges
aggregating $60,470, $268 and $410 on redemptions of Class B(1), Class B and
Class C shares, respectively, during the same period.

Note 5

MetLife announced that it has entered into an agreement to sell the Adviser as
part of a larger transaction to sell MetLife's asset management business to
BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset
management business is expected to occur in the first quarter of 2005. At the
time of the closing, the advisory agreement between the fund and the Adviser and
the distribution agreement between the fund and the Distributor will be
terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly
owned subsidiaries of BlackRock, will serve as investment adviser and
distributor, respectively.

A Special Meeting of Shareholders of the fund has been tentatively scheduled for
December 2004. At this meeting, shareholders of the fund will be asked to
consider and approve a plan of reorganization between the fund and the BlackRock
Mid-Cap Growth Equity Portfolio. If the proposed reorganization is approved by
shareholders of the fund, the BlackRock Mid-Cap Growth Equity Portfolio would
acquire substantially all of the assets and liabilities of the fund. In
exchange, shareholders of the fund would receive shares of the BlackRock Mid-Cap
Growth Equity Portfolio with an aggregate value equivalent to the aggregate net
asset value of their fund shares at the time of the transaction. If the proposed
reorganization is not approved by shareholders of the fund, the Board of
Trustees will need to consider other alternatives relating to the management and
operations of the fund, including without limitations, seeking an alternative
investment adviser for the fund or seeking shareholder approval to liquidate the
fund.*

*  The foregoing is not an offer to sell, nor a solicitation of an offer to buy,
   shares of any fund, nor is it a solicitation of any proxy.

Note 6
The Trustees have the authority to issue an unlimited number of shares of
beneficial interest at $0.001 par value per share.

These transactions break down by share class as follows:

REPORT OF

       Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders
of State Street Research Mid-Cap Growth Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio holdings, of State Street Research Mid-Cap Growth Fund (the
"Fund"), a series of State Street Research Capital Trust, as of September 30,
2004, and the related statement of operations for the year then ended, and the
statement of changes in net assets , and the financial highlights for each of
the two years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights for each of the years in the
three-year period ended September 30, 2002, were audited by other auditors whose
report dated November 8, 2002, expressed an unqualified opinion on such
financial highlights.

We conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States).Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of September 30, 2004, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of September 30, 2004, the results of its operations for the year then
ended, and the changes in its net assets and the financial highlights for each
of the two years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

FROM THE CHAIRMAN
      State Street Research

The pace of U.S. economic growth was robust over the past 12 months as the
economy advanced on all fronts. Gross domestic product (GDP) growth, a common
measure of economic growth, averaged just short of 4.0% for the period, solidly
above the economy's long-term trend rate of 3.0%. Our analysts expect the
economy to grow between 3.5% and 4.0% for the remainder of 2004 and into 2005.

Consumers continued to play a key role in the economy. Spending on retail goods,
autos and housing remained generally strong throughout the period. Retail sales
slowed during the summer months of 2004 as a result of higher energy prices and
weather-related events. But the pace of consumer spending picked up again in
September, as did consumer confidence, which see-sawed along with the outlook
for the labor market throughout the period.

The number of new jobs continued to fall short of expectations. In the spring,
more than one million new jobs were added to the economy. But job growth was
disappointing again during the summer months. The economy has yet to replace all
the jobs lost in the downturn of 2000-2001.

A pick-up in business spending was the bright spot in the economy. Industrial
production moved steadily higher, as did manufacturing capacity utilization.
Outlays for new equipment and construction enjoyed double-digit growth in the
second half of the period. Strong spending by business helped offset some of the
slowdown in consumer spending.

Stocks Stumble, Bonds Edge Higher

The U.S. stock market began the period on a strong note. However, the
double-digit gains it achieved over the twelve months covered by this report
were accumulated early in the period and the broad stock market indexes have
been essentially flat in 2004. By contrast, the bond market has held up in the
face of three increases in the Federal funds rate (a key short-term interest
rate) that occurred late in the period. The yield on the 10-year benchmark U.S.
Treasury ended the period only slightly higher than where it began, and bond
prices moved higher across all sectors.

Investing Despite Uncertainty

By all accounts, news on the economy and the markets has been overshadowed over
the past year by external events. As a result, many investors have remained on
the sidelines. With so much uncertainty, it may feel safer to wait out the
storm. Yet, it can be even more risky to try to time your entrances and exits as
the markets move through their natural cycles. If you're feeling uncertain about
your financial strategy, talk to your financial professional. With the advice
and guidance of a financial professional, you can keep your financial goals on
track.

Sincerely,

/s/ Richard S. Davis

         Discussion as of September 30, 2004

How State Street Research Emerging Growth Fund Performed

State Street Research Emerging Growth Fund (Class A shares, without sales
charge) returned 2.84% for the 12-month period ended September 30, 2004. The
fund underperformed the Russell 2000[RegTM] Growth Index and the Lipper
Small-Cap Growth Funds Average, which returned 11.92% and 9.19% respectively for
the period.

See pages 4 and 5 for additional performance data for Class A shares and for
performance data on other share classes.

Keep in mind that the performance data quoted represents past performance and is
no guarantee of future results. Current performance may be lower or higher than
the performance data quoted herein. For the most recent month-end performance
results, visit our website at www.ssrfunds.com. The fund's share price, yield
and return will fluctuate, and you may have a gain or loss when you sell your
shares. All returns assume reinvestment of capital gains distributions and
income dividends at net asset value. The returns shown do not reflect the
deduction of taxes that a shareholder would pay on fund distributions or the
redemption of fund shares.

Average annual total return without sales charge does not reflect the maximum
applicable sales charges. If the applicable sales charges were deducted,
performance results would be lower.

Average annual total return at maximum applicable sales charge reflects a
maximum 5.75% Class A share front-end sales charge.

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

The Russell 2000 Growth Index contains those stocks within the complete Russell
2000[RegTM] Index (a small-company index) that show above-average growth. The
index is unmanaged and does not take transaction charges into consideration. It
is not possible to invest directly in an index.

The Lipper Small-Cap Growth Funds Average shows the performance of a category of
mutual funds with similar goals. The Lipper average shows you how well the fund
has done compared to competing funds.

Reasons for the Fund's Performance

Market conditions changed dramatically over the past year. In 2003, small-cap
growth stocks were favored, but beginning in February 2004, investor sentiment
moved away from the sector, given rising energy prices, interest rate fears,
slowed economic growth and geopolitical concerns. Overall liquidity in the
sector lessened dramatically. This negative sentiment caused investors to look
beyond company-specific fundamentals and focus on broader issues. As a result,
individual stocks were subject to tremendous volatility. These factors, along
with selected stock disappointments, hurt the fund's performance.

Strong results from consumer issues Ask Jeeves, Boyd Gaming and Harman
International were offset by poor performances from Corinthian Colleges and
Alliance Gaming. We sold Corinthian Colleges after the company announced that
its earnings would fall short of expectations. We also sold Nektar Therapeutics,
a health care stock that lost ground after indications that European drug
regulators would not approve its inhaled insulin product, Exubera.

Technology returns also hurt results. The economic "soft patch" in June resulted
in an immediate weakness in technology spending, and a number of holdings in the
sector were hard hit. We reduced our exposure late in the period when it
appeared likely that the semiconductor industry had peaked.

Other sectors within the fund held up well, including energy, financials and
materials. We anticipate further strength in energy shares owing to continued
high oil, natural gas and coal prices. Gaming equipment makers and casino
operators continue to demonstrate robust growth irrespective of economic
conditions.

Looking Ahead

We believe that the fund is positioned for improved performance once the
uncertainties that are holding back investors are lifted. We believe that the
fund is invested in many solid companies with strong business prospects. And, we
continue to adhere to our disciplined, bottom-up fundamental investment process.

A Word about Risk

The major risks of stock investing include sudden and unpredictable drops in
value and period of lackluster performance. Emerging growth stocks of any size
company often have an above-average sensitivity to market fluctuations, as their
market prices tend to reflect future expectations. Small-company stocks may be
particularly sensitive, because they may be thinly traded. The fund may
underperform other stock funds during periods when small-cap stocks or emerging
growth stocks are out of favor.

Because financial markets and mutual fund strategies are constantly evolving, it
is 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.

PERFORMANCE

         Discussion as of September 30, 2004

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is not a guarantee of future results, long-term returns
can serve as an important context for evaluating recent performance. There are
three ways of measuring long-term performance: cumulative total returns, average
annual total 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

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.

Average Annual Total Return

Represents the rate you would have had to earn during each year of a given time
period in order to end up with the fund's actual cumulative return for those
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 10 Years

Similar to cumulative total return, but uses dollars rather than percentages,
and assumes that the lump sum you invested was $10,000 (less the applicable
maximum sales charge, if any) and compares fund performance to the performance
of a market index.

Cumulative and Average Annual Total Return at maximum applicable sales charge
reflect a maximum 5.75% Class A share front-end sales charge, or 5% Class B(1)
or Class B share or 1% Class C share contingent deferred sales charge, where
applicable. Performance for Class B(1) shares reflects Class B share performance
through December 31, 1998, and Class B(1) performance thereafter. Performance
for Class R shares reflects Class A share performance through April 2, 2003, and
Class R share performance thereafter. If the returns for Class B(1) and Class R
shares had reflected their current service/distribution (Rule 12b-1) fees for
the entire period, returns would have been lower. Class R and Class S shares,
offered without sales charge, are available through certain retirement plans and
special programs.

Performance results for the fund are increased by the voluntary reduction of
fund fees and expenses, without subsidization, performance would have been
lower. The Russell 2000 Growth Index contains those stocks within the complete
Russell 2000 Index (a small-company index) that show above-average growth. The
index is unmanaged and does not take transaction charges into consideration. It
is not possible to invest directly in an index.

About Your Fund Expenses

As a fund shareholder, you incur two types of costs: (1) Transaction costs,
which include sales charges, and (2) ongoing expenses, which include management
fees, service/distribution fees (12b-1) and "other" expenses. The examples below
illustrate the ongoing cost in dollars of investing in the fund and allow you to
compare these costs with the expenses of other funds. The examples are based on
a $1,000 investment at the beginning of the period and held for the entire
period from March 31, 2004, to September 30, 2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number shown for your
fund under the column "Expenses Paid during the Period."

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending account balance and expenses paid during the period.
To compare your fund's ongoing expenses with those of other funds, simply
compare this 5% hypothetical example with the 5% hypothetical examples shown in
the shareholder reports of other funds.

* Expenses are equal to the fund's annualized expense ratio multiplied by the
  average account value over the period, multiplied by the number of days in the
  period and then divided by the number of days in the year.

Please note that the expenses shown in the table are meant to highlight and help
you compare ongoing costs only and do not reflect transactional expenses such as
sales charges, which would result in higher total expenses. It should also be
noted that, for certain funds, expenses have been subsidized or reduced through
expense offset arrangements, which reduces costs for shareholders. Generally,
the fund expects that the expense subsidy or expense offset arrangement will
continue although there is no guarantee that it will. Please see the fund's
prospectus for more information.

Notes to Financial Statements
- --------------------------------------------------------------------------------
September 30, 2004

Note 1

State Street Research Emerging Growth Fund is a series of State Street Research
Capital Trust (the "Trust"), which is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended, as
an open-end management investment company.

The investment objective of the fund is to provide growth of capital. In seeking
to achieve its investment objective, the fund invests at least 65% of its total
assets in emerging growth companies, with an emphasis on small-cap companies.

The fund offers six classes of shares. Class A shares are subject to an initial
sales charge of up to 5.75% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) and Class B shares pay annual
service and distribution fees equal to 1.00% of average daily net assets and
automatically convert into Class A shares (which pay lower ongoing expenses) at
the end of eight years. Class B(1) and Class B shares are subject to a
contingent deferred sales charge on certain redemptions made within six years
and five years of purchase, respectively. Class B shares are offered only to
current shareholders through reinvestment of dividends and distributions or
through exchanges from existing Class B accounts of State Street Research funds.
From October 1, 2003, to March 18, 2004, Class B shares paid annual service and
distribution fees of 1.00%. Effective March 19, 2004, the annual service and
distribution fees paid by Class B shares were voluntarily reduced to 0.00%.
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 service and distribution fees equal to 1.00% of average daily net assets.
Class R shares are offered to retirement plans participating in certain
platforms sponsored by broker-dealers which may involve multiple fund families.
Class R shares pay a service and distribution fee of 0.50%. No sales charge is
imposed at the time of purchase or redemption of Class R shares. Class S shares
are only offered through certain retirement accounts, advisory accounts of State
Street Research & Management Company (the "Adviser"), an investment management
subsidiary of MetLife, Inc. ("MetLife"), 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 service or distribution fees. The fund's expenses are
borne prorata by each class, except that each class bears expenses, and has
exclusive voting rights with respect to provisions of the plans of distribution,
related specifically to that class. Income, expenses (other than service and
distribution fees), and realized and unrealized gains or losses on investments
are allocated to each class of shares based on its relative net assets. The
Trustees declare separate dividends on each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation

Values for listed equity securities reflect final sales 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 closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Short-term securities maturing within sixty days are valued at
amortized cost. Other securities, if any, are valued at their fair value as
determined in good faith under consistently applied procedures established by
and under the supervision of the Trustees. In the event that the market
quotations for a portfolio instrument are not deemed to be readily available,
the Investment Adviser's Valuation Committee determines the fair value for such
portfolio instrument. The fair value of any such portfolio instruments are
determined based upon a consideration of all available facts and information.
The fair valuation of a restricted

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


Notes (continued)
- --------------------------------------------------------------------------------

portfolio instrument reflects the inherent worth of the portfolio instrument,
without regard to the restrictive feature, adjusted for any diminution in value
resulting from the restrictive feature. The Investment Adviser and the Custodian
also monitor domestic and foreign markets and news information for any
developing events that may have an impact on the valuation of portfolio
instruments. Such monitoring includes general market news and financial market
information sources currently utilized in making investment decisions, trading
and investment personnel located abroad, foreign regional brokers, and/or
foreign custodians. The value assigned to these securities is based upon
available information at the time, and does not necessarily represent the amount
which might ultimately be realized upon sale.

B. Security Transactions

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered.

C. Net Investment Income

Net investment income is determined daily and consists of interest and dividends
accrued and discount earned, less the estimated daily expenses of the fund.
Interest income is accrued daily as earned. Dividend income is accrued on the
ex-dividend date. The fund is charged for expenses directly attributable to it,
while indirect expenses are allocated among all funds in the Trust.

D. Dividends

Dividends from net investment income 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 gains distributions are determined in accordance
with federal income tax regulations which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
due to differing treatments for wash sale deferrals.

E. Federal Income Taxes

No provision for federal income taxes is necessary because 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.

At September 30, 2004, the fund had a capital loss carryforward of $8,855,140
available, to the extent provided in regulations, to offset future capital
gains, if any, of which, $8,701,249, and $153,891 expire on September 30, 2010
and 2011, respectively.

In order to meet certain excise tax distribution requirements under Section 4982
of the Internal Revenue Code, the fund is required to measure and distribute
annually, if necessary, net capital gains realized during a twelve-month period
ending October 31. In this connection, the fund is permitted to defer into its
next fiscal year any net capital losses incurred between each November 1 and the
end of its fiscal year. From November 1, 2002, through September 30, 2003, the
fund incurred net capital losses of $1,297,187 and has deferred and treated such
losses as arising in the fiscal year ended September 30, 2004. From November 1,
2003, through September 30, 2004, the fund incurred net capital losses of
$19,009,241 and intends to defer and treat such losses as arising in the fiscal
year ended September 30, 2005.

To the extent book/tax differences are permanent in nature, such amounts are
reclassified within the capital accounts based on federal tax basis treatment.
The fund reclassified for book purposes amounts arising from permanent book/tax
differences primarily relating to net operating losses not utilized. At
September 30, 2004, the components of distributable earnings on a tax basis
differ from the amounts reflected in the Statement of Assets and Liabilities by
temporary book/tax differences largely arising from wash sales capital loss
carryforwards and post-October losses. At September 30, 2004, the tax basis
distributable earnings were $0 in undistributed ordinary income, $0 in
undistributed short-term capital gains and $0 in undistributed long-term gains.

F. Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America 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 these estimates.

G. 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 September
30, 2004, the value of the securities loaned and the value of collateral were
$107,484,977 and $110,134,986 (consisting entirely of cash collateral invested
in State Street Navigator Securities Lending Prime Portfolio), respectively. The
collateral was marked to market the next business day and made equal to at least
100% of the current market value of the loaned securities and accrued interest.
During the year ended September 30, 2004, income from securities lending
amounted to $137,821.

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 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 year ended September 30, 2004, the fees pursuant to such agreement
amounted to $2,550,085.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), 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, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the year ended September 30, 2004, the amount of such expenses allocated to the
fund was $607,693.

The fund has entered into an arrangement with its custodian whereby credits
realized as a result of directed brokerage commissions were used to reduce a
portion of the fund's expenses. During the year ended September 30, 2004, the
fund's custodian fees were reduced by $61,468 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$24,907 during the year ended September 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the year ended September 30, 2004, the amount of such expenses was
$108,379.

On February 19, 2004, the Distributor entered into an agreement with the NASD
resolving all outstanding issues relating to an investigation by the NASD of the
Distributor's e-mail retention practices and supervision of trading activity in
shares of the State Street Research funds. The Distributor, without admitting or
denying the allegations or the findings set forth in the agreement, and solely
for the purpose of the settlement, agreed to the entry of certain findings by
the NASD relating to the Distributor's compliance with document retention
requirements and the Distributor's supervision of and enforcement of shareholder
exchange limitations set forth in the funds' prospectuses. The agreement
contains no allegations or findings of fraudulent conduct by the Distributor. As
part of this agreement, the Distributor made a payment to the fund to compensate
the fund for losses relating to the exchange of fund shares beyond the annual
limit set forth in the fund's prospectus. The payment was allocated among the
fund's share classes as follows: $143,922 to Class A, $17,116 to Class B(1),
$13,661 to Class B, $16,147 to Class C, and $10,110 to Class S. These amounts
are shown in the total amount of $200,956 as "Net increase from payment by
affiliate" in the Statement of Operations.

Note 3

The Distributor and its affiliates may from time to time and in varying amounts
voluntarily assume some portion of fees or expenses relating to the fund. During
the year ended September 30, 2004, the amount of such expenses assumed by the
Distributor and its affiliates was $502,887.

Note 4

For the year ended September 30, 2004, purchases and sales of securities,
exclusive of short-term obligations, aggregated $962,758,623, and $682,502,599,
respectively.

Note 5

The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, 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(1), Class B, Class C and Class R shares. In addition, the fund pays
annual distribution fees of 0.05% of average daily net assets for Class A
shares. The fund pays annual distribution fees of 0.75% of average daily net
assets for Class B(1), Class B and Class C shares and 0.25% of average net
assets for Class R shares. From October 1, 2003, to March 18, 2004, Class B
shares paid annual service and distribution fees of 1.00%. Effective March 19,
2004, the annual service and distribution fees paid by Class B shares were
voluntarily reduced to 0.00%. The fund expects this waiver to continue, although
there is no guarantee that it will. The Distributor uses such payments for
personal services and/or the maintenance 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 year ended September 30, 2004, fees pursuant to such
plans amounted to $666,668, $260,001, $31,730, $250,142 and $12,070 for Class A,
Class B(1), Class B, Class C and Class R shares, respectively. For Class A,
Class B and Class C shares, the payments are intended to reimburse the
distributor for expenditures incurred under the plan, and any unused payments
are returnable to the fund.

As of September 30, 2004, there were $2,734,916, $6,138 and $1,512,555 for Class
A, B and Class C shares, respectively, of unreimbursed distribution and
shareholder servicing related expenses to be carried forward to future plan
years. For Class B(1) and R shares, the payments compensate the distributor for
services and expenditures incurred under the plan, and none of the payments are
returnable to the fund.

The fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of MetLife, earned initial sales charges aggregating
$428,159 and $451,555 on sales of Class A shares of the fund during the year
ended September 30, 2004, and that MetLife Securities, Inc. earned commissions
aggregating $542,639 and $4,955 on sales of Class B(1) and Class C shares, and
the Distributor collected contingent deferred sales charges aggregating $48,364,
$40 and $3,662 on redemptions of Class B(1), Class B and Class C shares,
respectively, during the same period.

Note 6

MetLife announced that it has entered into an agreement to sell the Adviser as
part of a larger transaction to sell MetLife's asset management business to
BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset
management business is expected to occur in the first quarter of 2005. At the
time of closing, the advisory agreement between the fund and the Adviser and the
distribution agreement between the fund and the Distributor will be terminated.
BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly owned
subsidiaries of BlackRock, will serve as investment adviser and distributor,
respectively.

A Special Meeting of Shareholders of the fund has been tentatively scheduled for
December 2004. At this meeting, shareholders of the fund will be asked to
consider and approve a plan of reorganization between the fund and the BlackRock
Emerging Growth Portfolio, a newly created series of the BlackRock Funds. If the
proposed reorganization is approved by shareholders of the fund, the BlackRock
Emerging Growth Portfolio would acquire substantially all of the assets and
liabilities of the fund. In exchange, shareholders of the fund would receive
shares of the BlackRock Emerging Growth Portfolio with an aggregate value
equivalent to the aggregate net asset value of their fund shares at the time of
the transaction. If the proposed reorganization is not approved by shareholders
of the fund, the Board of Trustees will need to consider other alternatives
relating to the management and operations of the fund, including without
limitations, seeking an alternative investment adviser for the fund or seeking
shareholder approval to liquidate the fund.*

* The foregoing is not an offer to sell, nor a solicitation of an offer to buy,
  shares of any fund, nor is it a solicitation of any proxy.

Note 7

The Trustees have the authority to issue an unlimited number of shares of
beneficial interest at $0.001 par value per share. At September 30, 2004, the
Adviser held 11,338 Class R shares.

REPORT OF

     Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders
of State Street Research Emerging Growth Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio holdings, of State Street Research Emerging Growth Fund (the
"Fund"), a series of State Street Research Capital Trust, as of September 30,
2004, and the related statement of operations for the year then ended, and the
statement of changes in net assets, and the financial highlights for each of the
two years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits. The financial highlights for each of the years in the
three-year period ended September 30, 2002, were audited by other auditors whose
report dated November 8, 2002, expressed an unqualified opinion on such
financial highlights.

We conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States).Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of September 30, 2004, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of September 30, 2004, the results of its operations for the year then
ended and the changes in its net assets, and the financial highlights for each
of the two years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

FROM THE CHAIRMAN
        State Street Research

The pace of U.S. economic growth was robust over the past 12 months as the
economy advanced on all fronts. Gross domestic product (GDP) growth, a common
measure of economic growth, averaged just short of 4.0% for the period, solidly
above the economy's long-term trend rate of 3.0%. Our analysts expect the
economy to grow between 3.5% and 4.0% for the remainder of 2004 and into 2005.

Consumers continued to play a key role in the economy. Spending on retail goods,
autos and housing remained generally strong throughout the period. Retail sales
slowed during the summer months of 2004 as a result of higher energy prices and
weather-related events. But the pace of consumer spending picked up again in
September, as did consumer confidence, which see-sawed along with the outlook
for the labor market throughout the period.

The number of new jobs continued to fall short of expectations. In the spring,
more than one million new jobs were added to the economy. But job growth was
disappointing again during the summer months. The economy has yet to replace all
the jobs lost in the downturn of 2000-2001.

A pick-up in business spending was the bright spot in the economy. Industrial
production moved steadily higher, as did manufacturing capacity utilization.
Outlays for new equipment and construction enjoyed double-digit growth in the
second half of the period. Strong spending by business helped offset some of the
slowdown in consumer spending.

Stocks Stumble, Bonds Edge Higher

The U.S. stock market began the period on a strong note. However, the
double-digit gains it achieved over the twelve months covered by this report
were accumulated early in the period and the broad stock market indexes have
been essentially flat in 2004. By contrast, the bond market has held up in the
face of three increases in the Federal funds rate (a key short-term interest
rate) that occurred late in the period. The yield on the 10-year benchmark U.S.
Treasury ended the period only slightly higher than where it began, and bond
prices moved higher across all sectors.

Investing Despite Uncertainty

By all accounts, news on the economy and the markets has been overshadowed over
the past year by external events. As a result, many investors have remained on
the sidelines. With so much uncertainty, it may feel safer to wait out the
storm. Yet, it can be even more risky to try to time your entrances and exits as
the markets move through their natural cycles. If you're feeling uncertain about
your financial strategy, talk to your financial professional. With the advice
and guidance of a financial professional, you can keep your financial goals on
track.

Sincerely,

/s/ Richard S. Davis

Average annual total return without sales charge does not reflect the maximum
applicable sales charges. If the applicable sales charges were deducted,
performance results would be lower.

Average annual total return at maximum applicable sales charge reflects a
maximum 5.75% Class A share front-end sales charge.

The Russell 2000 Value Index contains those stocks within the complete Russell
2000[RegTM] Index (a small-company index) that show below-average growth. The
index is unmanaged and does not take transaction charges into consideration. It
is not possible to invest directly in an index.

The Lipper Small-Cap Core Funds Average shows the performance of a category of
mutual funds with similar goals. The Lipper average shows you how well the fund
has done compared to competing funds.

Reasons for the Fund's Performance

Although the fund lagged its benchmark during the year, it posted solid gains.
The fund's strong absolute return was primarily the result of our investments in
the energy and materials sectors. Energy stocks benefited from higher crude oil
and natural gas prices. In the materials sector, U.S. Steel, Phelps Dodge and
Allegheny Technology gained as steel and copper prices increased in response to
a strengthening worldwide economy and robust economic growth in China. The fund
also benefited from an underweight position in the financial services sector,
which failed to keep pace with other areas of the market.

The fund's shortfall relative to its benchmark was the result of its emphasis on
economically sensitive stocks. This positioning proved costly in the second half
of the period as investors sought lower volatility in the stocks of larger
companies. The fund's performance was hindered especially by investments in the
producer durables and technology sectors. In producer durables, the
semiconductor and electronics industries faltered in the second half of the
period as it became clear that the U.S. economy had hit a "soft patch." MKS
Instruments, ATMI and Varian Semiconductor fell as a result of a slowdown in
demand. In technology, telecommunications equipment manufacturers also
disappointed.

Looking Ahead

We believe that continued signs of economic strength, an accommodative Federal
Reserve Board policy and resolution of the uncertainty surrounding the
presidential race could provide the catalysts for positive momentum in the stock
market going forward. In this environment, we believe that stock selection is
likely to drive returns. We will continue to focus our efforts on fundamental
research to identify stocks trading at a discount to the company's intrinsic
value. This approach has resulted in a modest increase in our emphasis on the
autos & transportation and materials & processing sectors. Although the fund
remains underweight in financial services stocks, we added to the sector by
selectively investing in insurance, investment management and brokerage names.
We also took advantage of the strength in our steel industry holdings to trim
positions in favor of more attractively valued opportunities.

A Word about Risk

The major risks of stock investing include sudden and unpredictable drops in
value and period of lackluster performance. Small-cap stocks can be particularly
sensitive to market movements, as they may be thinly traded and their market
prices tend to reflect future expectations. "Value" investing poses the
potential that a stock may not achieve its "expected" value if the circumstances
that cause the stock to be underpriced do not change.

PERFORMANCE

        Discussion as of September 30, 2004

These two pages focus on the fund's long-term track record. While a mutual
fund's past performance is not a guarantee of future results, long-term returns
can serve as an important context for evaluating recent performance. There are
three ways of measuring long-term performance: cumulative total returns, average
annual total 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

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.

Average Annual Total Return

Represents the rate you would have had to earn during each year of a given time
period in order to end up with the fund's actual cumulative return for those
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

Similar to cumulative total return, but uses dollars rather than percentages,
and assumes that the lump sum you invested was $10,000 (less the applicable
maximum sales charge, if any) and compares fund performance to the performance
of a market index.

Cumulative and Average Annual Total Return at maximum applicable sales charge
reflect a maximum 5.75% Class A share front-end sales charge, or 5% Class B(1)
or Class B share or 1% Class C share contingent deferred sales charge, where
applicable. Performance for Class B(1) shares reflects Class B share performance
through December 31, 1998, and Class B(1) performance thereafter. If the returns
for Class B(1) shares had reflected their current service/distribution (Rule
12b-1) fees for the entire period, returns would have been lower. Class S
shares, offered without sales charge, are available through certain retirement
plans and special programs.

Performance results for the fund are increased by the voluntary reduction of
fund fees and expenses, without subsidization, performance would have been
lower. The Russell 2000 Value Index contains those stocks within the Russell
2000 Index (a small-company index) that show below-average growth. The index is
unmanaged and does not take transaction charges into consideration. It is not
possible to invest directly in an index.

About Your Fund Expenses

As a fund shareholder, you incur two types of costs: (1) Transaction costs,
which include sales charges, and (2) ongoing expenses, which include management
fees, service/distribution fees (12b-1) and "other" expenses. The examples below
illustrate the ongoing cost in dollars of investing in the fund and allow you to
compare these costs with the expenses of other funds. The examples are based on
a $1,000 investment at the beginning of the period and held for the entire
period from March 31, 2004, to September 30, 2004.

Actual Fund Return is based on the fund's actual return and expenses. To
estimate the ongoing expenses you paid during the entire period shown, simply
divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number shown for your
fund under the column "Expenses Paid during the Period."

Hypothetical 5% Return is based on the fund's actual expense ratio and an
assumed rate of 5% per year before expenses. Please note that the return used is
not the fund's actual return; therefore, this information may not be used to
estimate your actual ending balance and expenses paid during the period. To
compare your fund's ongoing expenses with those of other funds, simply compare
this 5% hypothetical example with the 5% hypothetical examples shown in the
shareholder reports of other funds.

* Expenses are equal to the fund's annualized expense ratio multiplied by the
  average account value over the period, multiplied by the number of days in the
  period and then divided by the number of days in the year.

Please note that the expenses shown in the table are meant to highlight and help
you compare ongoing costs only and do not reflect transactional expenses such as
sales charges, which would result in higher total expenses. It should also be
noted that, for certain funds, expenses have been subsidized or reduced through
expense offset arrangements, which reduces costs for shareholders. Generally,
the fund expects that the expense subsidy or expense offset arrangement will
continue although there is no guarantee that it will. Please see the fund's
prospectus for more information.

Notes to Financial Statements
- --------------------------------------------------------------------------------
September 30, 2004
Note 1

State Street Research Aurora Fund is a series of State Street Research Capital
Trust (the "Trust"), which is a Massachusetts business trust and is registered
under the Investment Company Act of 1940, as amended, as an open-end management
investment company.

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 at least 65% of its total assets in small-cap value
stocks.

The fund offers five classes of shares. Class A shares are subject to an initial
sales charge of up to 5.75% and pay annual service and distribution fees equal
to 0.30% of average daily net assets. Class B(1) shares pay annual service and
distribution fees equal to 1.00% of average daily net assets and automatically
convert into Class A shares (which pay lower ongoing expenses) at the end of
eight years. Class B(1) and Class B shares are subject to a contingent deferred
sales charge on certain redemptions made within six years and five years of
purchase, respectively. Class B shares are offered only to current shareholders
through reinvestment of dividends and distributions or through exchanges from
existing Class B accounts of State Street Research funds and also automatically
convert into Class A shares at the end of eight years. Class B shares may also
be subject to annual service and distribution fees equal to 1.00% of average
daily net assets. However, these fees are currently waived under the terms of
the distribution plan. Currently, the annual service and distribution fees paid
by Class B shares have been voluntarily reduced to 0.00%. 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 service and
distribution fees equal to 1.00% of average daily net assets. Class S shares are
only offered through certain retirement accounts, advisory accounts of State
Street Research & Management Company (the "Adviser"), an investment management
subsidiary of MetLife, Inc. ("MetLife"), 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 service or distribution fees. The fund's expenses are
borne prorata by each class, except that each class bears expenses, and has
exclusive voting rights with respect to provisions of the plans of distribution,
related specifically to that class. Income, expenses (other than service and
distribution fees), and realized and unrealized gains or losses on investments
are allocated to each class of shares based on its relative net assets. The
Trustees declare separate dividends on each class of shares.

The following significant accounting policies are consistently followed by the
fund in preparing its financial statements, and such policies are in conformity
with accounting principles generally accepted in the United States of America.

A. Investment Valuation

Values for listed equity securities reflect final sales 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 closing prices
supplied through such system. If not quoted on the Nasdaq system, such
securities are valued at prices obtained from independent brokers. In the
absence of recorded sales, valuations are at the mean of the closing bid and
asked quotations. Short-term securities maturing within sixty days are valued at
amortized cost. Other securities, if any, are valued at their fair value as
determined in good faith under consistently applied procedures established by
and under the supervision of the Trustees. In the event that the market
quotations for a portfolio instrument are not deemed to be readily available,
the Investment Adviser's Valuation Committee determines the fair value for such
portfolio instrument. The fair value of any such portfolio instruments are
determined based upon a consideration of all available facts and information.
The fair value of a restricted portfolio instrument reflects the inherent worth
of the portfolio instrument, without regard to the restrictive feature, adjusted
for any diminution in value resulting from the restrictive feature. The
Investment Adviser and the Custodian also monitor domestic and foreign markets
and news information for any developing events that

may have an impact on the valuation of portfolio instruments. Such monitoring
includes general market news and financial market information sources currently
utilized in making investment decisions, trading and investment personnel
located abroad, foreign regional brokers, and/or foreign custodians. The value
assigned to these securities is based upon available information at the time,
and does not necessarily represent the amount which might ultimately be realized
upon sale.

B. Security Transactions

Security transactions are accounted for on the trade date (date the order to buy
or sell is executed). Realized gains or losses are reported on the basis of
identified cost of securities delivered.

As part of the custodian contract between the custodian bank and the fund, the
custodian bank has a lien on the securities of the fund to the extent permitted
by the fund's investment restriction to cover any advances made by the custodian
bank for the settlement of securities purchased by the fund. At September 30,
2004 the payable to the custodian bank of $980,526 represents the amount due for
cash advance for the settlement of the security purchased.

C. Net Investment Income

Net investment income is determined daily and consists of interest and dividends
accrued and discount earned, less the estimated daily expenses of the fund.
Interest income is accrued daily as earned. Dividend income is accrued on the
ex-dividend date. The fund is charged for expenses directly attributable to it,
while indirect expenses are allocated among all funds in the Trust.

D. Dividends

Dividends from net investment income 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. For the year ended September 30, 2004, the fund has designated $0
as ordinary income dividends and $1,642,569 as long-term capital gain
distributions.

Income dividends and capital gains distributions are determined in accordance
with federal income tax regulations which may differ from accounting principles
generally accepted in the United States of America. The difference is primarily
due to differing treatments for wash sale deferrals.

E. Federal Income Taxes

No provision for federal income taxes is necessary because 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.

To the extent book/tax differences are permanent in nature, such amounts are
reclassified within the capital accounts based on federal tax basis treatment.
The fund reclassified for book purposes amounts arising from permanent book/tax
differences primarily relating to non-taxable dividend adjustments and REIT sell
adjustments. At September 30, 2004, the components of distributable earnings on
a tax basis differ from the amounts reflected in the Statement of Assets and
Liabilities by temporary book/tax differences largely arising from wash sales.
At September 30, 2004, the tax basis distributable earnings were $51,565,898 in
undistributed ordinary income and $285,689,445 in undistributed long-term gains.

F. Estimates

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America 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 these estimates.

G. 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 September
30, 2004, the value of the securities loaned and the value of collateral were
$820,559,939 and $840,778,353 (including $840,459,698 of cash collateral
invested in State Street Navigator Securities Lending Prime Portfolio and
$318,655 of U.S. government obligations), respectively. The collateral was
marked to market the next business day and made equal to at least 100% of the
current market value of the loaned securities and accrued interest. During the
year ended September 30, 2004, income from securities lending amounted to
$1,508,066 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 year ended September 30, 2004, the fees pursuant to such
agreement amounted to $29,179,140.

State Street Research Service Center, a division of State Street Research
Investment Services, Inc., the Trust's principal underwriter (the
"Distributor"), 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, MetLife receives a
fee for maintenance of the accounts of certain shareholders who are participants
in sponsored arrangements, such as employee benefit plans, through or under
which shares of the fund may be purchased. Total shareholder service costs are
allocated to each fund in the same ratios as the transfer agent costs. During
the year ended September 30, 2004, the amount of such expenses allocated to the
fund was $5,284,788.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$119,304 during the year ended September 30, 2004.

The fund has agreed to pay the Adviser for certain administrative costs incurred
in providing other assistance and services to the fund. The fee was based on a
fixed amount that has been allocated equally among the State Street Research
funds. During the year ended September 30, 2004, the amount of such expenses was
$96,535.

On February 19, 2004, the Distributor entered into an agreement with the NASD
resolving all outstanding issues relating to an investigation by the NASD of the
Distributor's e-mail retention practices and supervision of trading activity in
shares of the State Street Research funds. The Distributor, without admitting or
denying the allegations or the findings set forth in the agreement, and solely
for the purpose of the settlement, agreed to the entry of certain findings by
the NASD relating to the Distributor's compliance with document retention
requirements and the Distributor's supervision of and enforcement of shareholder
exchange limitations set forth in the funds' prospectuses. The agreement
contains no allegations or findings of fraudulent conduct by the distributor. As
part of this agreement, the Distributor made a payment to State Street Research
Aurora Fund to compensate the fund for losses relating to the exchange of fund
shares beyond the annual limit set forth in the fund's prospectus. The payment
was allocated among the fund's share classes as follows: $256,999 to Class A;
$58,986 to Class B(1); $25,392 to Class B; $60,506 to Class C; and $24,574 to
Class S. These amounts are shown in the total amount of $426,457 as "Net
increase from payment by affiliate" in the Statement of Operations.

Note 3

For the year ended September 30, 2004, purchases and sales of securities,
exclusive of short-term obligations, aggregated $1,105,387,917, and
$1,158,894,827, respectively.

Note 4

The Trust has adopted plans of distribution pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Under the plans, 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(1) and Class C shares. In addition, the fund pays annual distribution
fees of 0.05% of average daily net assets for Class A shares. The fund pays
annual distribution fees of 0.75% of average daily net assets for Class B(1) and
Class C shares. Currently, the annual service and distribution fees paid by
Class B shares have been reduced to 0.00%. The fund expects this waiver to
continue, although there is no guarantee it will. The Distributor uses such
payments for personal services and/or the maintenance of shareholder accounts,
to reimburse securities dealers for distribution and marketing services, to
furnish ongoing assistance to investors and to defray a portion

                                            State Street Research Aurora Fund 13


of its distribution and marketing expenses. For the year ended September 30,
2004, fees pursuant to such plans amounted to $6,237,602, $4,701,624 and
$4,853,723 for Class A, Class B(1) and Class C shares, respectively. For Class
A, Class B and Class C shares, the payments are intended to reimburse the
distributor for expenditures incurred under the plan, and any unused payments
are returnable to the fund. As of September 30, 2004, there were $33,153,047,
$65,986 and $9,332,153 for Class A, Class B and Class C shares, respectively, of
unreimbursed distribution and shareholder servicing related expenses to be
carried forward to future plan years. For Class B(1) shares, the payments
compensate the distributor for services and expenditures incurred under the
plan, and none of the payments are returnable to the fund. During the year ended
September 30, 2004 the Distributor reimbursed a total of $707,239 to Class B
shares of the fund reflecting the estimated excess of payments received over
costs incurred under the plan. This amount is shown as "Reimbursement of
distribution fees" in the Statement of Operations.

The fund has been informed that the Distributor and MetLife Securities, Inc., a
wholly owned subsidiary of MetLife, earned initial sales charges aggregating
$1,745,932 and $2,193,737, respectively, on sales of Class A shares of the fund
during the year ended September 30, 2004, and that MetLife Securities, Inc.
earned commissions aggregating $2,523,913 and $48,625 on sales of Class B(1) and
Class C shares, and the Distributor collected contingent deferred sales charges
aggregating $641,167, $37 and $19,193 on redemptions of Class B(1), Class B and
Class C shares, respectively, during the same period.

Note 5

MetLife announced that it has entered into an agreement to sell the Advisor as
part of a larger transaction to sell MetLife's asset management business to
BlackRock, Inc. ("BlackRock"). The acquisition by BlackRock of MetLife's asset
management business is expected to occur in the first quarter of 2005. At the
time of the closing, the advisory agreement between the fund and the Adviser and
the distribution agreement between the fund and the Distributor will be
terminated. BlackRock Advisors, Inc. and BlackRock Distributors, Inc., wholly
owned subsidiaries of BlackRock, will serve as investment adviser and
distributor, respectively.

A Special Meeting of Shareholders of the fund has been tentatively scheduled for
December 2004. At this meeting, shareholders of the fund will be asked to
consider and approve a plan of reorganization between the fund and the BlackRock
Mid-Cap Value Equity Portfolio II, a newly created series of the BlackRock
Funds. If the proposed reorganization is approved by shareholders of the fund,
the BlackRock Mid-Cap Value Equity Portfolio II would acquire substantially all
of the assets and liabilities of the fund. In exchange, shareholders of the fund
would receive shares of the BlackRock Mid-Cap Value Equity Portfolio II with an
aggregate value equivalent to the aggregate net asset value of their fund shares
at the time of the transaction. If the proposed reorganization is not approved
by shareholders of the fund, the Board of Trustees will need to consider other
alternatives relating to the management and operations of the fund, including
without limitations, seeking an alternative investment adviser for the fund or
seeking shareholder approval to liquidate the fund.*

* The foregoing is not an offer to sell, nor a solicitation of an offer to buy,
  shares of any fund, nor is it a solicitation of any proxy.

Note 6

The Trustees have the authority to issue an unlimited number of shares of
beneficial interest at $0.001 par value per share.

These transactions break down by share class as follows:

REPORT OF

     Independent Registered Public Accounting Firm

To the Board of Trustees and Shareholders
of State Street Research Aurora Fund:

We have audited the accompanying statement of assets and liabilities, including
the portfolio holdings, of State Street Research Aurora Fund (the "Fund"), a
series of State Street Research Capital Trust, as of September 30, 2004, and the
related statement of operations for the year then ended, and the statement of
changes in net assets and the financial highlights for each of the two years in
the period then ended. These financial statements and financial highlights are
the responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. The financial highlights for each of the years in the three-year period
ended September 30, 2002, were audited by other auditors whose report dated
November 8, 2002, expressed an unqualified opinion on such financial highlights.

We conducted our audits in accordance with standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements. Our procedures included confirmation of
securities owned as of September 30, 2004, by correspondence with the custodian
and brokers; where replies were not received from brokers, we performed other
auditing procedures. An audit also includes assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of the
Fund as of September 30, 2004, the results of its operations for the year then
ended, and the changes in its net assets and the financial highlights for each
of the two years in the period then ended, in conformity with accounting
principles generally accepted in the United States of America.

    subcontracted with or overseen by another investment adviser) and any
    entity controlling, controlled by, or under common control with the
