FROM THE CHAIRMAN
           State Street Research

The U.S. economy grew at a solid pace during the six-month period from January
1, 2004, to June 30, 2004. Gross Domestic Product (GDP), a common measure of
economic growth, rose 3.9% for the first quarter of 2004. Estimates for
second-quarter growth, which will not be released until well into the third
quarter, range from 2.5% to 4.0%.

Consumer confidence wavered early in the period as the number of new jobs added
to the economy fell below expectations. However, when the job picture brightened
in April and May, consumer confidence tracked higher. More than 1.2 million jobs
were added to the economy in the second half of the period, and the quality of
new jobs also improved, as reported by the U.S. Labor Department.

Although most of the news was upbeat during the period, durable goods orders
dipped in February and again in April and May--news that surprised most
analysts. And after months of strong sales, auto dealerships reported a decline
in June.

Yet, consumers continued to fuel the economy, pumping dollars into the retail
and housing markets. Sales of new and existing homes soared as homebuyers
anticipated higher mortgage rates ahead. Corporate profits staged a solid
rebound, making it easier for companies to increase spending, especially on
information technology, electronic equipment and new jobs.

As the period wore on, it became clear that the days of record-low short-term
interest rates were coming to an end. On the last day of the period, the Federal
Reserve Board raised a key short-term interest rate--the federal funds
rate--from 1.0% to 1.25%.

Stocks Edge Higher, Bonds Stumble

The stock market moved sharply higher in the first months of the year, fueled by
a substantial increase in profits for 2003 and expectations of continued profit
growth in 2004. However, a host of worries stopped the major indexes in their
tracks as the period wore on. As investors grew more cautious about interest
rates and the threat of terrorist attacks, stocks retreated. For the six months,
the S&P 500 Index gained a modest 3.44%. Small-cap stock gains were higher. The
energy sector was the stock market's strongest performer.

High-yield bonds continued to rally as the year began. However, they also
stalled along with the stock market late in the period. Mortgage bonds eked out
a small gain, but most other segments of the bond market reported negative
returns.

Looking Ahead

Any time the financial markets deliver negative returns, it can be disheartening
for investors. However, the seeds of a new market rally are often sown in
periods of weakness and decline. A diversified portfolio and a long-term
perspective on the markets can make it easier to weather periods of
volatility--and more likely that you will reap the potential benefits in better
times. We urge you to talk to your investment professional about your investment
plan.

As always, we thank you for investing with State Street Research funds. We look
forward to helping you achieve your long-term financial goals.

Sincerely,

/s/ Richard S. Davis

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

How State Street Research Exchange Fund Performed

State Street Research Exchange Fund (Class A shares, without sales charge)
returned 3.13% for the six-month period ended June 30, 2004. That was slightly
less than the performance of the S&P 500 Index, which was 3.44% over the same
period. However, the fund outperformed the Exchange Fund Average, which was
2.77% for the period.

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.

The S&P 500 Index (officially the "Standard & Poor's 500 Composite Stock Price
Index") is an unmanaged index of 500 U.S. stocks. The index does not take
transaction charges into consideration. It is not possible to invest directly
in the index. The Exchange Fund Average is an average created by State Street
Research using data provided by Lipper, Inc. The average consists of funds with
similar goals and shows how well the fund has done compared to competing funds.

Reasons for the Fund's Performance

The equity markets were volatile in the six-month period, as economic strength
and strong earnings battled against rising interest rates, high oil prices and
turmoil in Iraq. Investors favored financial services in the first quarter, but
sentiment turned to energy, health care and select conglomerates in the second
quarter. Thus, the portfolio's exposure to financial services, as well as
integrated oil and energy, buoyed overall portfolio returns.

Relative weakness in the technology, utilities and transportation sectors
partially offset these gains, resulting in the fund's slight underperformance
relative to the S&P 500 Index. The largest individual contributors to the
fund's return were Millipore, Exxon Mobil and Boeing. Vodafone, Wyeth and Intel
were the greatest detractors. During the period, we reduced our positions in
AstraZeneca and Johnson & Johnson, as well as in Exxon Mobil and British
Petroleum.

Looking Ahead

We expect the equity markets to remain volatile through the second half of the
year, given difficult year-over-year corporate earnings comparisons, the
upcoming presidential election and rising interest rates. With that expectation
in mind, we have positioned the portfolio with an overweight in health care,
integrated oils and consumer staples stocks. The fund's positions in consumer
discretionary, financial services and utilities, which historically have lagged
in an environment of rising interest rates, are underweight relative to its
benchmark.

A Word about Risk

The major risks of stock investing include sudden and unpredictable drops in
value and period of lackluster performance. The fund may invest in companies
with some international business, and also may invest in foreign companies;
therefore, the fund is subject to the risks associated with international
investing, such as changes in exchange rates, and different government
regulations, economic conditions and accounting standards.

Notes to Unaudited Financial Statements
- --------------------------------------------------------------------------------
June 30, 2004

Note 1
State Street Research Exchange Fund is a series of State Street Research
Exchange 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 fund is presently the only
series of the Trust.

The investment objective of the fund is to provide long-term growth of capital
and consequent long-term growth of income. In seeking to achieve its investment
objective, the fund invests primarily in common stocks, or securities
convertible into common stocks, that have long-term growth potential.

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. If trading or events occurring in
other markets after the close of the principal market in which foreign
securities are traded, and before the close of business of the fund, are
expected to materially affect the value of these securities, then they are
valued at their fair value taking this trading or these events into account.

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.

D. Dividends
Dividends from net investment income are declared and paid or reinvested
quarterly. Net realized short-term capital gains, if any, are distributed
annually.

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 non-taxable redemptions in kind and the
disposition of securities that have different bases for financial reporting and
tax purposes.

The fund hereby designates the maximum amount allowable of its net taxable
income as qualified dividend income as provided in the Jobs and Growth Tax
Relief Reconciliation Act of 2003. This amount has been reflected on Form 1099
for the calendar year 2003.

E. Federal Income Taxes
No provision for federal income taxes is necessary with respect to net
investment income because the fund has elected to qualify under Subchapter M of
the Internal Revenue Code and its policy is to distribute substantially all of
such income within the prescribed time periods. The fund retains and designates
as undistributed gains all of its taxable net long-term capital gains and pays
federal income taxes thereon on behalf of the shareholders.

At December 31, 2003, the fund had a capital loss carryforward of $12,862,555
available, to the extent provided in regulations, to offset future capital
gains, if any, of which $5,749,972 and $7,112,583 expire on December 31, 2009
and 2010, respectively.

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 June 30, 2004, there were no loaned securities. During the six months
ended June 30, 2004, income from securities lending amounted to $2,665 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 0.50% 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 six months ended June 30, 2004, the fees pursuant to
such agreement amounted to $767,326.

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
redemption of shares of the fund. Total shareholder service costs are allocated
to each fund in the same ratios as the transfer agent costs. During the six
months ended June 30, 2004, the amount of such expenses allocated to the fund
was $459.

The fund has entered into an arrangement with its transfer agent whereby
credits realized as a result of uninvested cash balances were used to reduce a
portion of the fund's expense. During the six months ended June 30, 2004, the
fund's transfer agent fees were reduced by $65 under this arrangement.

The fees of the Trustees not currently affiliated with the Adviser amounted to
$14,672 during the six months ended June 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 six months ended June 30, 2004, the amount of such
expenses was $46,550.

Note 3
For the six months ended June 30, 2004, exclusive of short-term investments and
U.S. government obligations, purchases and sales of securities, including
$8,580,214 representing redemptions in kinds, aggregated $0 and $8,580,214,
respectively.

Note 4
The Trustees have the authority to issue an unlimited number of shares of
beneficial interest at $0.001 par value per share. At June 30, 2004, the
Adviser held 13,766 shares of the fund.
