DREYFUS STOCK INDEX FUND
- -----------------------------------------------------------------------------
LETTER TO SHAREHOLDERS
Dear Shareholder:
We are pleased to provide you with this semi-annual report for the Dreyfus
Stock Index Fund for the six-month period ended June 30, 1998. Over this period,
your Fund produced a total return of 17.51%.* This compares with a total return
of 17.72%** for the Standard & Poor's 500 Composite Stock Price Index, which the
Fund is designed to mirror. The difference is accounted for by transaction costs
and other Fund expenses.
ECONOMIC REVIEW
Fears of Federal Reserve Board tightening appear to have eased due to
accumulating evidence of slower overall economic growth since the spring.
Monetary tightening has been deterred by the Asian financial crisis. The Fed's
main domestic concern is that the tight labor market has begun to fuel faster
wage growth across many industries. However, rising wages have still not meant
rising prices. Instead, this cost-price mix threatens to further erode corporate
profit margins. Market interest rates have already reflected the slower economy,
and the interest rate curve has become quite flat.
The shift to slower economic growth this spring is largely due to the drag
from Asia's recession, but may well be reinforced this summer by the multiplier
impacts of the General Motors strike. Among broader economic factors, the trade
deficit has widened sharply due to both weak exports and strong growth in
imports. Also, inventories soared earlier this year, potentially creating some
drag on future production. However, slowing industrial output has largely been
met by shortening the manufacturing work week, not by cutting jobs. Hence, the
shift to slower growth has not relieved the tightness in the labor market.
Instead, the virtual absence of bad news has left consumers to enjoy the
benefits of rising real wages and lower interest rates that, in turn, have
boosted spending and home ownership.
Although growth in corporate profits has slowed in many sectors in the past
year, consensus estimates of future profit growth continue to be cut by many
analysts. Profit margins had already begun to shrink under the weight of rising
labor costs, making companies' reported profits increasingly dependent on growth
of sales. Overall profits could thus prove quite vulnerable to a period of
significantly slower economic growth.
Virtually all Treasury market interest rates have already fallen near to the
floor set by the Federal Funds rate. This implies that further substantial
interest rate drops are unlikely unless the economy weakens enough to justify
action by the Fed to ease credit.
MARKET OVERVIEW
Measured broadly, the half-year ended June 30, 1998 was another period of
solid advance for the stock market. Yet that general statement did not apply to
all categories of stocks.
To be sure, the S& P 500 achieved a new record of 17.72% at the end of the
six-month period. The Dow Jones Industrial Average (DJIA), while it didn't reach
its all-time record, nonetheless gained 14.16% for the six months, closing the
half-year above 9000. Small and medium size stocks, however, underperformed the
large cap issues. The Standard & Poor's MidCap 400 Index gained just 8.63% for
the half-year, and the Russell 2000 index of small cap issues advanced a mere
4.93%.
The first calendar quarter provided most of the strength for the six months,
particularly among the large cap companies. In the April-June quarter, the S&P
500 gained 3.32% and the DJIA 2.15%, while the Russell 2000 actually dropped by
4.66%.
Stock categories that were strongest during the half-year included financials,
particularly banks, brokerages, insurance and diversified financial services;
technology, especially communications and computer issues; and cyclical consumer
stocks such as advertising, airlines, automotive, broadcasting and home
construction.
The weak categories for the period included precious metals, oil drilling and
oilfield suppliers, and some industrial issues.
Corporate profits dropped sharply from the strong pace of last year. According
to the statistical service First Call, profits for stocks in the S&P 500 were
expected to show a rise of just 2.3% for the second quarter, compared to 3.8% in
the first quarter. Of course there were optimists forecasting a hefty rise in
profits for later this year and early 1999, which could potentially propel stock
prices upward. Yet most investors seemed preoccupied with the here and now,
which included the strike at General Motors plants and the continuing fallout
from financial troubles in Japan and Southeast Asia.
As expected, the Fed at its last meeting made no change in interest rates,
even though inflationary pressures are a constant worry for the Fed. The reason
for their inaction may well have been the precarious state of some economies
elsewhere in the world and the desire not to precipitate a major correction in
the US stock market. Even so, the Fed thought it timely to issue a stern warning
to banks not to become over-extended with unwise loans, which happened in the
1980s.
Despite warnings like this, and that stock prices are extremely high
historically in relation to earnings and cash flow, investors still appeared
eager to own equities. Moreover, surveys of consumer sentiment continued to show
that the average consumer was more confident about the future than had been the
case in a generation.
We thank you for your interest in this Dreyfus-managed Fund and look forward
to continuing to serve your investment needs.
Sincerely,
[Steven Falci, signature logo]

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
NOTE 1--SIGNIFICANT ACCOUNTING POLICIES:
Dreyfus Stock Index Fund (the "Fund" ) is registered under the Investment
Company Act of 1940 ("Act") as a non-diversified open-end management investment
company, that is intended to be a funding vehicle for variable annuity contracts
and variable life insurance policies to be offered by the separate accounts of
life insurance companies. The Fund' s investment objective is to provide
investment results that correspond to the price and yield performance of
publicly traded common stocks as represented by the Standard and Poor's 500
Composite Stock Price Index. The Dreyfus Corporation ("Dreyfus") serves as the
Fund' s manager and Mellon Equity Associates ("Mellon Equity"), an affiliate of
Dreyfus, serves as the Fund' s index manager. Boston Safe Deposit and Trust
Company, an affiliate of Dreyfus, is the Fund's custodian. Dreyfus is a direct
subsidiary of Mellon Bank, N.A. Premier Mutual Fund Services, Inc. is the
distributor of the Fund's shares, which are sold without a sales charge.
The Fund' s financial statements are prepared in accordance with generally
accepted accounting principles which may require the use of management estimates
and assumptions. Actual results could differ from those estimates.
(A) PORTFOLIO VALUATION: Investments in securities (including financial
futures) are valued at the last sales price on the securities exchange on which
such securities are primarily traded or at the last sales price on the national
securities market. Securities not listed on an exchange or the national
securities market, or securities for which there were no transactions, are
valued at the average of the most recent bid and asked prices. Bid price is used
when no asked price is available. Securities for which there are no such
valuations are valued at fair value as determined in good faith under the
direction of the Board of Trustees. Investments denominated in foreign
currencies are translated to U.S. dollars at the prevailing rates of exchange.
(B) SECURITIES TRANSACTIONS AND INVESTMENT INCOME: Securities transactions are
recorded on a trade date basis. Realized gain and loss from securities
transactions are recorded on the identified cost basis. Dividend income is
recognized on the ex-dividend date and interest income, including, where
applicable, amortization of discount on investments, is recognized on the
accrual basis.
(C) DIVIDENDS TO SHAREHOLDERS: Dividends are recorded on the ex-dividend date.
Dividends from investment income-net are declared and paid on a quarterly basis.
Dividends from net realized capital gain are normally declared and paid
annually, but the Fund may make distributions on a more frequent basis to comply
with the distribution requirements of the Internal Revenue Code. To the extent
that net realized capital gain can be offset by capital loss carryovers, if any,
it is the policy of the Fund not to distribute such gain.
(D) FEDERAL INCOME TAXES: It is the policy of the Fund to continue to qualify
as a regulated investment company, if such qualification is in the best
interests of its shareholders, by complying with the provisions available to
certain investment companies, as defined in applicable sections of the Internal
Revenue Code, and to make distributions of taxable income sufficient to relieve
it from substantially all Federal income and excise taxes.
NOTE 2--BANK LINE OF CREDIT:
The Fund participates with other Dreyfus-managed funds in a $600 million
redemption credit facility (" Facility" ) to be utilized for temporary or
emergency purposes, including the financing of redemptions. In connection
therewith, the Fund has agreed to pay commitment fees on its pro rata portion of
the Facility. Interest is charged to the Fund at rates based on prevailing
market rates in effect at the time of borrowings. During the period ended June
30, 1998, the Fund did not borrow under the Facility.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)
NOTE 3--MANAGEMENT FEE AND OTHER TRANSACTIONS WITH AFFILIATES:
(A) Pursuant to an Investment Advisory Agreement with Dreyfus, the investment
advisory fee is computed at the annual rate of .245 of 1% of the value of the
Fund' s average daily net assets, and is payable monthly. Dreyfus has agreed to
pay Mellon Equity a monthly fee at the annual rate of .095 of 1% of the value of
the Fund's average daily net assets. Dreyfus has undertaken from January 1, 1998
until such a time as they give shareholders at least 180 days notice to the
contrary that if any full fiscal year the Fund's aggregate expenses (exclusive
of brokerage commissions, transaction fees, commitment fees and extraordinary
expenses) exceed an annual rate of .40 of 1% of the value of the Fund's average
daily net assets, the Fund may deduct from the payments to be made to Dreyfus,
or Dreyfus will bear, such excess expense. During the period ended June 30,
1998, there was no expense reimbursement pursuant to the Investment Advisory
Agreement.
(B) Under the Shareholder Services Plan, the Fund reimburses Dreyfus Service
Corporation, a wholly-owned subsidiary of Dreyfus, an amount not to exceed an
annual rate of .25 of 1% of the value of the Fund's average daily net assets for
certain allocated expenses with respect to servicing and/or maintaining
shareholder accounts.
The Fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of the
Manager, under a transfer agency agreement for providing personnel and
facilities to perform transfer agency services for the Fund. During the period
ended June 30, 1998, the Fund was charged $213 pursuant to the transfer agency
agreement.
(C) Each director who is not an "affiliated person" as defined in the Act
receives from the Fund an annual fee of $2,500 and an attendance fee of $500 per
meeting. The Chairman of the Board receives an additional 25% of such
compensation.
NOTE 4--SECURITIES TRANSACTIONS:
(A) The aggregate amount of purchases and sales of investment securities,
excluding short-term securities and financial futures, during the period ended
June 30, 1998 amounted to $461,251,750 and $12,153,964, respectively.
The Fund may invest in financial futures contracts in order to gain exposure
to or protect against changes in the market. The Fund is exposed to market risk
as a result of changes in the value of the underlying financial instruments.
Investments in financial futures require the Fund to "mark to market" on a daily
basis, which reflects the change in the market value of the contract at the
close of each day's trading. Typically, variation margin payments are received
or made to reflect daily unrealized gains or losses. When the contracts are
closed, the Fund recognizes a realized gain or loss. These investments require
initial margin deposits with a custodian, which consist of cash or cash
equivalents, up to approximately 10% of the contract amount. The amount of these
deposits is determined by the exchange or Board of Trade on which the contract
is traded and is subject to change. Contracts open at June 30, 1998 are set
forth in the Statement of Financial Futures.
(B) At June 30, 1998, accumulated net unrealized appreciation on investments
and financial futures was $748,587,230, consisting of $776,017,971 gross
unrealized appreciation and $27,430,741 gross unrealized depreciation.
At June 30, 1998, the cost of investments for Federal income tax purposes was
substantially the same as the cost for financial reporting purposes (see the
Statement of Investments).
