A LETTER FROM THE CHIEF EXECUTIVE OFFICER

Dear Shareholder:

We are pleased to present this annual report for Dreyfus Stock Index Fund, Inc. covering the 12-month period from January 1, 2016 through December 31, 2016. For information about how the fund performed during the reporting period, as well as general market perspectives, we provide a Discussion of Fund Performance on the pages that follow.

Stocks and bonds advanced over 2016 despite bouts of market volatility stemming from various economic and political developments. In January, stocks declined sharply and long-term interest rates fell in response to sluggish global economic growth, falling commodity prices, and worries following the first increase in short-term U.S. interest rates in nearly a decade. However, equities began a sustained rebound in February when U.S. monetary policymakers refrained from additional rate hikes, other central banks eased their monetary policies, and commodity prices recovered. After a bout of volatility in June stemming from the United Kingdom’s referendum to leave the European Union, stocks generally continued to climb over the summer. Stock prices moderated in advance of U.S. elections, but markets subsequently rallied to new highs in anticipation of changes in U.S. fiscal and tax policies. In the bond market, yields of high-quality government bonds moved lower over much of the reporting period amid robust investor demand for current income, but yields surged higher after the election due to expectations of rising interest rates. Corporate-backed bonds fared especially well in this environment.

The transition to a new U.S. president and ongoing global economic headwinds suggest that volatility may persist in the financial markets. Some asset classes and industry groups seem likely to benefit from a changing economic and geopolitical landscape, while others probably will face challenges. Consequently, selectivity seems likely to be an important determinant of investment success in 2017. As always, we encourage you to discuss the implications of our observations with your financial advisor.

Thank you for your continued confidence and support.

Sincerely,

Mark D. Santero

Chief Executive Officer

DISCUSSION OF FUND PERFORMANCE

For the period of January 1, 2016 through December 31, 2016, as provided by Thomas J. Durante, CFA, Karen Q. Wong, CFA, and Richard A. Brown, CFA, Portfolio Managers of Mellon Capital Management Corporation, Sub-Investment Adviser

Market and Fund Performance Overview

For the 12-month period ended December 31, 2016, Dreyfus Stock Index Fund’s Initial shares produced a total return of 11.71%, and its Service shares produced a total return of 11.44%.¹ In comparison, the S&P 500 Index (the “Index”), the fund’s benchmark, provided a total return of 11.94% for the same period.²

U.S. stocks achieved solid returns in 2016 on the strength of positive economic growth and expectations of changing fiscal, tax, and regulatory policies under a new presidential administration. The differences in returns between the fund and the Index were primarily the result of transaction costs and operating expenses that are not reflected in the Index’s results.

The Fund’s Investment Approach

The fund seeks to match the total return of the Index by generally investing in all 500 stocks in the Index in proportion to their respective weighting. Often considered a proxy for the stock market in general, the Index is made up of 500 common stocks chosen to reflect the industries of the U.S. economy.

Each company’s stock is weighted by the number of available float shares (i.e., those shares available to investors) divided by the total shares outstanding, which means larger companies with more available float shares have greater representation in the Index than smaller ones. The fund attempts to have a correlation between its performance and that of the Index of at least .95 before fees and expenses. A correlation of 1.00 would mean that the fund and the Index were perfectly correlated.

Economic and Political Developments Drove Equity Markets

U.S. stocks moved sharply lower over the opening weeks of 2016 due to weakening commodity prices, disappointing global economic data, and higher short-term U.S. interest rates. However, equities began a dramatic recovery in February and rallied through the spring in response to rebounding commodity prices, global monetary easing, and indications that additional U.S. rate increases would be delayed.

The market’s advance faltered in June over concerns regarding the United Kingdom’s referendum to leave the European Union, but the decline proved short lived. By early July, the market had regained most of its lost ground, and encouraging U.S. economic data helped the Index advance further over the summer. Stocks gave back some of their previous gains in October when investors became more cautious ahead of the presidential election. After the election, stocks again rallied strongly, and the Index achieved record highs as investors anticipated higher government spending, lower corporate taxes, and a less stringent regulatory environment.

Energy and Financial Stocks Led the 2016 Market

After suffering particularly steep declines early in 2016 in response to plummeting oil prices, the energy sector came roaring back to end the year as the top performing sector within the Index. The energy sector’s rebound was propelled by recovering commodity prices, which enhanced the earnings of oil-and-gas producers that had cut costs and become more efficient during the downturn. Energy infrastructure companies, such as pipeline operators, fared especially well,

DISCUSSION OF FUND PERFORMANCE (continued)

while oil refiners generally lagged sector averages. The financials sector languished for much of 2016, in part due to the dampening effect of low interest rates on profit margins. However, banks, capital markets companies, and other financial institutions gained considerable ground in the weeks after the presidential election as investors looked forward to higher interest rates stemming from new pro-growth fiscal policies, an easing of costly banking regulations, lower corporate tax rates, and higher trading volumes.

The industrials sector also fared better than broader market averages, largely due to post-election expectations of rising government spending on infrastructure development and repair. This development especially benefited large equipment producers and railroads. Meanwhile, airlines gained value when reduced industry capacity led to higher ticket prices, and aerospace-and-defense companies rallied in anticipation of higher military spending.

In contrast, only one of the Index’s market segments produced negative absolute returns in 2016: the health care sector. Biotechnology firms and pharmaceutical developers contended throughout the year with industrywide pricing pressures and the derailment of some high-profile mergers. Toward the end of the year, service providers and health care insurers struggled with uncertainty surrounding the future of the Affordable Care Act. In the real estate sector, real estate investment trusts (REITs) gave back previous gains amid waning investor demand for dividend-paying stocks. In addition, REITs that focus on malls and other retail properties were hurt by a generally sluggish retail environment as more consumers made purchases over the internet.

Replicating the Performance of the Index

Although we do not actively manage the fund’s investments in response to macroeconomic trends, we have been encouraged by the stock market’s resilience in the face of political change and persistent global economic headwinds. As always, we have continued to monitor the factors considered by the fund’s investment model in light of current market conditions.

January 17, 2017

Equities are subject generally to market, market sector, market liquidity, issuer, and investment style risks, among other factors, to varying degrees, all of which are more fully described in the fund’s prospectus.

The fund is only available as a funding vehicle under variable life insurance policies or variable annuity contracts issued by insurance companies. Individuals may not purchase shares of the fund directly. A variable annuity is an insurance contract issued by an insurance company that enables investors to accumulate assets on a tax-deferred basis for retirement or other long-term goals. The investment objective and policies of Dreyfus Stock Index Fund, made available through insurance products may be similar to other funds managed by Dreyfus. However, the investment results of the fund may be higher or lower than, and may not be comparable to, those of any other Dreyfus fund.

¹Total return includes reinvestment of dividends and any capital gains paid. Past performance is no guarantee of future results. Share price and investment return fluctuate such that upon redemption, fund shares may be worth more or less than their original cost. The fund’s performance does not reflect the deduction of additional charges and expenses imposed in connection with investing in variable insurance contracts, which will reduce returns.

Using the SEC’s method to compare expenses

The Securities and Exchange Commission (SEC) has established guidelines to help investors assess fund expenses. Per these guidelines, the table below shows your fund’s expenses based on a $1,000 investment, assuming a hypothetical 5% annualized return. You can use this information to compare the ongoing expenses (but not transaction expenses or total cost) of investing in the fund with those of other funds. All mutual fund shareholder reports will provide this information to help you make this comparison. Please note that you cannot use this information to estimate your actual ending account balance and expenses paid during the period.

Expenses and Value of a $1,000 Investment
assuming a hypothetical 5% annualized return for the six months ended December 31, 2016
	Initial Shares		Service Shares
Expenses paid per $1,000†		$1.42		$2.69
Ending value (after expenses)		$1,023.73		$1,022.47

^†Expenses are equal to the fund’s annualized expense ratio of .28% for Initial shares and .53% for Service shares, multiplied by the average account value over the period, multiplied by 184/366 (to reflect the one-half year period).

NOTES TO FINANCIAL STATEMENTS

NOTE 1—Significant Accounting Policies:

Dreyfus Stock Index Fund, Inc. (the “fund”) is registered under the Investment Company Act of 1940, as amended (the “Act”), as a non-diversified open-end management investment company. The fund is only offered to separate accounts established by insurance companies to fund variable annuity contracts and variable life insurance policies. The fund’s investment objective is to seek to match the total return of the S&P 500^® Index. The Dreyfus Corporation (the “Manager” or “Dreyfus”), a wholly-owned subsidiary of The Bank of New York Mellon Corporation (“BNY Mellon”), serves as the fund’s investment adviser. Mellon Capital Management Corporation (“Mellon Capital”), an indirect wholly-owned subsidiary of BNY Mellon, serves as the fund’s index manager.

MBSC Securities Corporation (the “Distributor”), a wholly-owned subsidiary of Dreyfus, is the distributor of the fund’s shares, which are sold without a sales charge. The fund is authorized to issue 400 million shares of $.001 par value Common Stock in each of the following classes of shares: Initial shares (250 million shares authorized) and Service shares (150 million shares authorized). Initial shares are subject to a Shareholder Services Plan fee and Service shares are subject to a Distribution Plan fee. Each class of shares has identical rights and privileges, except with respect to the Distribution Plan, Shareholder Services Plan and the expenses borne by each class, the allocation of certain transfer agency costs, and certain voting rights. Income, expenses (other than expenses attributable to a specific class), and realized and unrealized gains or losses on investments are allocated to each class of shares based on its relative net assets.

The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification is the exclusive reference of authoritative U.S. generally accepted accounting principles (“GAAP”) recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under authority of federal laws are also sources of authoritative GAAP for SEC registrants. The fund’s financial statements are prepared in accordance with GAAP, which may require the use of management estimates and assumptions. Actual results could differ from those estimates.

The fundenters into contracts that contain a variety of indemnifications. The fund’s maximum exposure under these arrangements is unknown. The fund does not anticipate recognizing any loss related to these arrangements.

(a) Portfolio valuation: The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability

29

NOTES TO FINANCIAL STATEMENTS (continued)

in an orderly transaction between market participants at the measurement date (i.e., the exit price). GAAP establishes a fair value hierarchy that prioritizes the inputs of valuation techniques used to measure fair value. This hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

Additionally, GAAP provides guidance on determining whether the volume and activity in a market has decreased significantly and whether such a decrease in activity results in transactions that are not orderly. GAAP requires enhanced disclosures around valuation inputs and techniques used during annual and interim periods.

Various inputs are used in determining the value of the fund’s investments relating to fair value measurements. These inputs are summarized in the three broad levels listed below:

Level 1—unadjusted quoted prices in active markets for identical investments.

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.).

Level 3—significant unobservable inputs (including the fund’s own assumptions in determining the fair value of investments).

The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. Valuation techniques used to value the fund’s investments are as follows:

Investments in securities are valued at the last sales price on the securities exchange or national securities market on which such securities are primarily traded. Securities listed on the National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price that day, at the last sales price. For open short positions, asked prices are used for valuation purposes. Bid price is used when no asked price is available. Registered investment companies that are not traded on an exchange are valued at their net asset value. All of the preceding securities are generally categorized within Level 1 of the fair value hierarchy.

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

30

the most recent bid and asked prices. U.S. Treasury Bills are valued at the mean price between quoted bid prices and asked prices by an independent pricing service (the “Service”) approved by the fund’s Board of Directors (the “Board”). These securities are generally categorized within Level 2 of the fair value hierarchy.

The Service is engaged under the general supervision of the Board.

Fair valuing of securities may be determined with the assistance of a pricing service using calculations based on indices of domestic securities and other appropriate indicators, such as prices of relevant American Depository Receipts and futures. Utilizing these techniques may result in transfers between Level 1 and Level 2 of the fair value hierarchy.

When market quotations or official closing prices are not readily available, or are determined not to reflect accurately fair value, such as when the value of a security has been significantly affected by events after the close of the exchange or market on which the security is principally traded (for example, a foreign exchange or market), but before the fund calculates its net asset value, the fund may value these investments at fair value as determined in accordance with the procedures approved by the Board. Certain factors may be considered when fair valuing investments such as: fundamental analytical data, the nature and duration of restrictions on disposition, an evaluation of the forces that influence the market in which the securities are purchased and sold, and public trading in similar securities of the issuer or comparable issuers. These securities are either categorized within Level 2 or 3 of the fair value hierarchy depending on the relevant inputs used.

For restricted securities where observable inputs are limited, assumptions about market activity and risk are used and are generally categorized within Level 3 of the fair value hierarchy.

Futures, which are traded on an exchange, 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 on each business day and are generally categorized within Level 1 of the fair value hierarchy.

The following is a summary of the inputs used as of December 31, 2016in valuing the fund’s investments:

^†See Statement of Investments for additional detailed categorizations.
^††Amount shown represents unrealized (depreciation) at period end.

At December 31, 2016, there were no transfers between levels of the fair value hierarchy.

(b)Securities transactions and investment income: Securities transactions are recorded on a trade date basis. Realized gains and losses 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, accretion of discount and amortization of premium on investments, is recognized on the accrual basis.

Pursuant to a securities lending agreement with The Bank of New York Mellon, a subsidiary of BNY Mellon and an affiliate of Dreyfus, the fund may lend securities to qualified institutions. It is the fund’s policy that, at origination, all loans are secured by collateral of at least 102% of the value of U.S. securities loaned and 105% of the value of foreign securities loaned. Collateral equivalent to at least 100% of the market value of securities on loan is maintained at all times. Collateral is either in the form of cash, which can be invested in certain money market mutual funds managed by Dreyfus, or U.S. Government and Agency securities. The fund is entitled to receive all dividends, interest and distributions on securities loaned, in addition to income earned as a result of the lending transaction. Should a borrower fail to return the securities in a timely manner, The Bank of New York Mellon is required to replace the securities for the benefit of the fund or credit the fund with the market value of the unreturned securities and is subrogated to the fund’s rights against the borrower and the collateral. Additionally, the contractual maturity of

32

security lending transactions are on an overnight and continuous basis. During the period ended December 31, 2016, The Bank of New York Mellon earned $38,866 from lending portfolio securities, pursuant to the securities lending agreement.

(c) Affiliated issuers: Investments in other investment companies advised by Dreyfus are defined as “affiliated” under the Act. Investments in affiliated investment companies during the period ended December 31, 2016 were as follows:

Affiliated Investment Company	Value 12/31/2015 ($)	Purchases ($)	Sales ($)	Value 12/31/2016 ($)	Net Assets (%)

^†During the period ended December 31, 2016, Dreyfus Institutional Cash Advantage Fund was acquired by Dreyfus Institutional Preferred Money Market Fund.
^††Formerly Dreyfus Institutional Preferred Plus Money Market Fund.
(d) Dividends and distributions to shareholders: Dividends and distributions are recorded on the ex-dividend date. Dividends from investment income-net are normally declared and paid quarterly. Dividends from net realized capital gains, if any, 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 of 1986, as amended (the “Code”). To the extent that net realized capital gains can be offset by capital loss carryovers, it is the policy of the fund not to distribute such gains. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

33

NOTES TO FINANCIAL STATEMENTS (continued)

(e) 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 applicable provisions of the Code, and to make distributions of taxable income sufficient to relieve it from substantially all federal income and excise taxes.

As of and during the period ended December 31, 2016, the fund did not have any liabilities for any uncertain tax positions. The fund recognizes interest and penalties, if any, related to uncertain tax positions as income tax expense in the Statement of Operations. During the period ended December 31, 2016, the fund did not incur any interest or penalties.

Each tax year in the four-year period ended December 31, 2016 remains subject to examination by the Internal Revenue Service and state taxing authorities.

At December 31, 2016, the components of accumulated earnings on a tax basis were as follows: undistributed ordinary income $2,592,892, undistributed capital gains $53,202,654 and unrealized appreciation $1,230,149,301.

The tax character of distributions paid to shareholders during the fiscal periods ended December 31, 2016 and December 31, 2015 were as follows: ordinary income $42,944,377 and $39,952,720, and long-term capital gains $72,805,278 and $58,167,339, respectively.

During the period ended December 31, 2016, as a result of permanent book to tax differences, primarily due to tax basis deemed dividends, the fund increased accumulated undistributed investment income-net by $815,256 and decreased accumulated net realized gain (loss) on investments by the same amount. Net assets and net asset value per share were not affected by this reclassification.

NOTE 2—Bank Lines of Credit:

The fund participates with other Dreyfus-managed funds in an $810 million unsecured credit facility led by Citibank, N.A. and a $300 million unsecured credit facility provided by The Bank of New York Mellon (each, a “Facility”), each to be utilized primarily for temporary or emergency purposes, including the financing of redemptions. Prior to October 5, 2016, the unsecured credit facility with Citibank, N.A. was $555 million and prior to January 11, 2016, the unsecured credit facility with Citibank, N.A. was $480 million. In connection therewith, the fund has agreed to pay its pro rata portion of commitment fees for each Facility. Interest is charged to the fund based on rates determined pursuant to the terms of

34

the respective Facility at the time of borrowing. During the period ended December 31, 2016, the fund did not borrow under the Facilities.

NOTE 3—Management Fee, Index-Management Fee and Other Transactions with Affiliates:

(a) Pursuant to a management agreement (the “Agreement”) with Dreyfus, the management fee is computed at the annual rate of .245% of the value of the fund’s average daily net assets and is payable monthly.

Pursuant to an index-management agreement (the “Index Agreement”), Dreyfus has agreed to pay Mellon Capital a monthly index-management fee at the annual rate of .095% of the value of the fund’s average daily net assets. Pursuant to the Index Agreement, Mellon Capital pays the Custodian for its services to the fund.

(b) Under the Distribution Plan adopted pursuant to Rule 12b-1 under the Act, Service shares pay the Distributor for distributing its shares, for servicing and/or maintaining Service shares’ shareholder accounts and for advertising and marketing for Service shares. The Distribution Plan provides for payments to be made at an annual rate of .25% of the value of the Service shares’ average daily net assets. The Distributor may make payments to Participating Insurance Companies and to brokers and dealers acting as principal underwriter for their variable insurance products. The fees payable under the Distribution Plan are payable without regard to actual expenses incurred. During the period ended December 31, 2016, Service shares were charged $490,582 pursuant to the Distribution Plan.

(c) Under the Shareholder Services Plan, Initial shares reimburse the Distributor at an amount not to exceed an annual rate of .25% of the value of its average daily net assets for certain allocated expenses with respect to servicing and/or maintaining Initial shares’ shareholder accounts. During the period ended December 31, 2016, Initial shares were charged $2,350 pursuant to the Shareholder Services Plan.

The fund has arrangements with the transfer agent and the custodian whereby the fund may receive earnings credits when positive cash balances are maintained, which are used to offset transfer agency and custody fees. For financial reporting purposes, the fund includes net earnings credits as an expense offset in the Statement of Operations.

The fund compensates Dreyfus Transfer, Inc., a wholly-owned subsidiary of Dreyfus, under a transfer agency agreement for providing transfer agency and cash management services for the fund. The majority of transfer agency fees are comprised of amounts paid on a per account basis, while cash management fees are related to fund subscriptions and

redemptions. During the period ended December 31, 2016, the fund was charged $1,453 for transfer agency services and $132 for cash management services. These fees are included in Shareholder servicing costs in the Statement of Operations. Cash management fees were partially offset by earnings credits of $62.

During the period ended December 31, 2016, the fund was charged $9,640 for services performed by the Chief Compliance Officer and his staff.

The components of “Due to The Dreyfus Corporation and affiliates” in the Statement of Assets and Liabilities consist of: management fees $459,028, Distribution Plan fees $42,782, Chief Compliance Officer fees $7,314 and transfer agency fees $262.

(d) Each Board member also serves as a Board member of other funds within the Dreyfus complex. Annual retainer fees and attendance fees are allocated to each fund based on net assets.

NOTE 4—Securities Transactions:

The aggregate amount of purchases and sales of investment securities, excluding short-term securities and futures, during the period ended December 31, 2016, amounted to $80,246,534 and $151,853,033, respectively.

Derivatives:A derivative is a financial instrument whose performance is derived from the performance of another asset. Each type of derivative instrument that was held by the fund during the period ended December 31, 2016 is discussed below.

Futures: In the normal course of pursuing its investment objective, the fund is exposed to market risk, including equity price risk,as a result of changes in value of underlying financial instruments. The fund invests in futures in order to manage its exposure to or protect against changes in the market. A futures contract represents a commitment for the future purchase or a sale of an asset at a specified date. Upon entering into such contracts, these investments require initial margin deposits with a counterparty, which consist of cash or cash equivalents. 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. Accordingly, variation margin payments are received or made to reflect daily unrealized gains or losses which are recorded in the Statement of Operations. When the contracts are closed, the fund recognizes a realized gain or loss which is reflected in the Statement of Operations. There is minimal counterparty credit risk to the fund with futures since they are exchange traded, and the

36

exchange guarantees the futures against default. Futures open at December 31, 2016 are set forth in the Statement of Futures.

The following summarizes the average market value of derivatives outstanding duringthe period ended December 31, 2016:

	Average Market Value ($)
Equity futures	27,969,643

At December 31, 2016, the cost of investments for federal income tax purposes was $982,148,775; accordingly, accumulated net unrealized appreciation on investments was $1,230,149,301, consisting of $1,297,591,402 gross unrealized appreciation and $67,442,101 gross unrealized depreciation.

NOTE 5—Pending Legal Matters:

The fund and many other entities have been named as defendants in numerous pending litigations as a result of their participation in the leveraged buyout transaction (“LBO”) of the Tribune Company (“Tribune”). The cases allege that Tribune took on billions of dollars of debt in the LBO to purchase its own stock from shareholders at $34 per share. The LBO was executed in a two-step transaction: shares were repurchased by Tribune in a tender offer in June 2007 and then in a go-private merger in December 2007. In 2008, approximately one year after the LBO was concluded, Tribune filed for bankruptcy protection under Chapter 11. Thereafter, in approximately June 2011, certain Tribune creditors filed dozens of complaints in various courts throughout the country alleging that the payments made to shareholders in the LBO were “fraudulent conveyances” under state and/or federal law, and that the shareholders must return the payments they received for their shares to satisfy the plaintiffs’ unpaid claims. These cases were consolidated for coordinated pre-trial proceedings in a multi-district litigation in the United States District Court for the Southern District of New York titled In re Tribune Company Fraudulent Conveyance Litigation (S.D.N.Y. Nos. 11-md-2296 and 12-mc-2296 (RJS) (“Tribune MDL”)).

In addition, there was a case pending in United States Bankruptcy Court for the District of Delaware brought by the Unsecured Creditors Committee of the Tribune Company that has since been transferred to the Tribune MDL (formerly The Official Committee of Unsecured Creditors of Tribune Co. v. FitzSimons, et al., Bankr. D. Del. Adv. Pro. No. 10-54010 (KJC)) (“FitzSimons case”). The case was originally filed on November 1, 2010. In a Fourth Amended Complaint filed in November 2012, among other claims, the Creditors Committee sought recovery under the Bankruptcy

37

NOTES TO FINANCIAL STATEMENTS (continued)

Code for alleged “fraudulent conveyances” from more than 5,000 Tribune shareholders (“Shareholder Defendants”), including the fund, and a defendants’ class of all shareholders who tendered their Tribune stock in the LBO and received cash in exchange. There were 35 other counts in the Fourth Amended Complaint that did not relate to claims against Shareholder Defendants, but instead were brought against parties directly involved in approval or execution of the leveraged buyout. On January 10, 2013, pursuant to the Tribune bankruptcy plan, Mark S. Kirchner, as Litigation Trustee for the Tribune Litigation Trust, became the successor plaintiff to the Creditors Committee in this case. The case is now proceeding as: Mark S.Kirchner, as Litigation Trustee for the Tribune Litigation Trust v. FitzSimons, et al., S.D.N.Y. No. 12-cv-2652 (RJS). On August 1, 2013, the plaintiff filed a Fifth Amended Complaint with the Court. The Fifth Amended Complaint contains more detailed allegations regarding the steps Tribune took in consideration and execution of the LBO, but did not change the legal basis for the claim previously alleged against the Shareholder Defendants.

On November 6, 2012, a motion to dismiss was filed in the Tribune MDL that applied to most, but not all, of the cases in the Tribune MDL. On September 23, 2013 Judge Sullivan granted the motion to dismiss on standing grounds, after rejecting defendants’ preemption arguments. By granting the motion, Judge Sullivan dismissed nearly 50 cases in the Tribune MDL. The fund was a defendant in at least one of the dismissed cases. The motion had no effect on the FitzSimons case, which had been stayed.

On September 30, 2013, plaintiffs appealed the motion to dismiss decision to the U.S. Court of Appeals for the Second Circuit. On October 28, 2013, certain defendants cross-appealed from Judge Sullivan’s decision, seeking review of the arguments that Judge Sullivan rejected in his decision. On March 29, 2016, the Second Circuit issued its decision on the appeal and cross-appeal. A panel of three judges unanimously affirmed the dismissal on the grounds that the plaintiffs’ claims were preempted by section 546(e) of the Bankruptcy Code. On April 12, 2016, the plaintiffs/appellants filed a petition with the Second Circuit requesting rehearing of the appeal by the same panel of judges and/or rehearing en banc by all judges on the Second Circuit. On July 22, 2016, the Second Circuit denied both requests for rehearing. On September 9, 2016, Plaintiffs filed a petition for certiorari with the U.S. Supreme Court. A brief in opposition to the petition was filed on behalf of defendants on October 24, 2016. Plaintiffs filed a reply brief on November 4, 2016. As of February 2, 2017, the Supreme Court has not ruled on the petition.

38

In the FitzSimons case, a “global” motion to dismiss the fraudulent transfer claim asserted against the Shareholder Defendants, which applies equally to all Shareholder Defendants including the fund, was filed on May 23, 2014 and briefing was completed in July 2014. On January 9, 2017, Judge Sullivan entered an order granting the “global” motion and dismissing the claim against all the Shareholder Defendants. On February 2, 2017, the plaintiff filed a request to seek leave to appeal with the court. As of February 2, 2017, the Court had not ruled on the request.

At this stage in the proceedings, it is not possible to assess with any reasonable certainty the probable outcomes of the pending litigations. Consequently, at this time, management is unable to estimate the possible loss that may result.

REPORT OF INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM

Shareholders and Board of Directors
Dreyfus Stock Index Fund, Inc.

We have audited the accompanying statement of assets and liabilities of Dreyfus Stock Index Fund, Inc., including the statements of investments and futures, as of December 31, 2016, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended, and the financial highlights for each of the five 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.

We conducted our audits in accordance with the 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. We were not engaged to perform an audit of the Fund’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2016 by correspondence with the custodian and others. 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 Dreyfus Stock Index Fund, Inc., at December 31, 2016, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended, and the financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.

EX-99.CODE ETH

THE DREYFUS FAMILY OF FUNDS

CODE OF ETHICS FOR PRINCIPAL EXECUTIVE

AND SENIOR FINANCIAL OFFICERS

1.Covered Officers/Purpose of the Code

This code of ethics (the "Code") for the investment companies within the complex (each, a "Fund") applies to each Fund's Principal Executive Officer, Principal Financial Officer, Principal Accounting Officer or Controller, or other persons performing similar functions, each of whom is listed on Exhibit A(the "Covered Officers"), for the purpose of promoting:

·honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;

·full, fair, accurate, timely and understandable disclosure in reports and documents that the Fund files with, or submits to, the Securities and Exchange Commission (the "SEC") and in other public communications made by the Fund;

·compliance with applicable laws and governmental rules and regulations;

·the prompt internal reporting of violations of the Code to an appropriate person or persons identified in the Code; and

·accountability for adherence to the Code.

Each Covered Officer should adhere to a high standard of business ethics and should be sensitive to situations that may give rise to actual as well as apparent conflicts of interest.

2.Covered Officers Should Handle Ethically Actual and Apparent Conflicts of Interest

Overview. A "conflict of interest" occurs when a Covered Officer's private interest interferes with the interests of, or his service to, the Fund.  For example, a conflict of interest would arise if a Covered Officer, or a member of his family, receives improper personal benefits as a result of his position with the Fund.

Certain conflicts of interest arise out of the relationships between Covered Officers and the Fund and already are subject to conflict of interest provisions in the Investment Company Act of 1940, as amended (the "Investment Company Act"), and the Investment Advisers Act of 1940, as amended (the "Investment Advisers Act"). For example, Covered Officers may not individually engage in certain transactions (such as the purchase or sale of securities or other property) with the Fund because of their status as "affiliated persons" of the Fund. The compliance programs and procedures of the Fund and the Fund's investment adviser (the "Adviser") are designed to prevent, or identify and correct, violations of these provisions. The Code does not, and is not intended to, repeat or replace these programs and procedures, and the circumstances they cover fall outside of the parameters of the Code.

Although typically not presenting an opportunity for improper personal benefit, conflicts arise from, or as a result of, the contractual relationship between the Fund and the Adviser of which the Covered Officers are also officers or employees.  As a result, the Code recognizes that the Covered Officers, in the ordinary course of their duties (whether formally for the Fund or for the Adviser, or for both), will be involved in establishing policies and implementing decisions that will have different effects on the Adviser and the Fund. The participation of the Covered Officers in such activities is inherent in the contractual relationship between the Fund and the Adviser and is consistent with the performance by the Covered Officers of their duties as officers of the Fund and, if addressed in conformity with the provisions of the Investment Company Act and the Investment Advisers Act, will be deemed to have been handled ethically. In addition, it is recognized by the Fund's Board that the Covered Officers also may be officers or employees of one or more other investment companies covered by this or other codes of ethics.

Other conflicts of interest are covered by the Code, even if such conflicts of interest are not subject to provisions in the Investment Company Act and the Investment Advisers Act.  Covered Officers should keep in mind that the Code cannot enumerate every possible scenario.  The overarching principle of the Code is that the personal interest of a Covered Officer should not be placed improperly before the interest of the Fund.

Each Covered Officer must:

·not use his personal influence or personal relationships improperly to influence investment decisions or financial reporting by the Fund whereby the Covered Officer would benefit personally to the detriment of the Fund;

·not cause the Fund to take action, or fail to take action, for the individual personal benefit of the Covered Officer rather than the benefit of the Fund; and

·not retaliate against any employee or Covered Officer for reports of potential violations that are made in good faith.

3.Disclosure and Compliance

·Each Covered Officer should familiarize himself with the disclosure requirements generally applicable to the Fund within his area of responsibility;

·each Covered Officer should not knowingly misrepresent, or cause others to misrepresent, facts about the Fund to others, whether within or outside the Fund, including to the Fund's Board members and auditors, and to governmental regulators and self-regulatory organizations;

·each Covered Officer should, to the extent appropriate within his area of responsibility, consult with other officers and employees of the Fund and the Adviser with the goal of promoting full, fair, accurate, timely and understandable disclosure in the reports and documents the Fund files with, or submits to, the SEC and in other public communications made by the Fund; and

·it is the responsibility of each Covered Officer to promote compliance with the standards and restrictions imposed by applicable laws, rules and regulations.

4.Reporting and Accountability

Each Covered Officer must:

·upon adoption of the Code (or thereafter, as applicable, upon becoming a Covered Officer), affirm in writing to the Board that he has received, read, and understands the Code;

·annually thereafter affirm to the Board that he has complied with the requirements of the Code; and

·notify the Adviser's General Counsel (the "General Counsel") promptly if he knows of any violation of the Code.  Failure to do so is itself a violation of the Code.

The General Counsel is responsible for applying the Code to specific situations in which questions are presented under it and has the authority to interpret the Code in any particular situation. However, waivers sought by any Covered Officer will be considered by the Fund's Board.

The Fund will follow these procedures in investigating and enforcing the Code:

·the General Counsel will take all appropriate action to investigate any potential violations reported to him;

·if, after such investigation, the General Counsel believes that no violation has occurred, the General Counsel is not required to take any further action;

·any matter that the General Counsel believes is a violation will be reported to the Board;

·if the Board concurs that a violation has occurred, it will consider appropriate action, which may include: review of, and appropriate modifications to, applicable policies and procedures; notification to appropriate personnel of the Adviser or its board; or dismissal of the Covered Officer;

·the Board will be responsible for granting waivers, as appropriate; and

·any waivers of or amendments to the Code, to the extent required, will be disclosed as provided by SEC rules.

5.Other Policies and Procedures

The Code shall be the sole code of ethics adopted by the Fund for purposes of Section 406 of the Sarbanes-Oxley Act of 2002 and the rules and forms applicable to registered investment companies thereunder. The Fund's, its principal underwriter's and the Adviser's codes of ethics under Rule 17j-1 under the Investment Company Act and the Adviser's additional policies and procedures, including its Code of Conduct, are separate requirements applying to the Covered Officers and others, and are not part of the Code.

6.Amendments 

The Code may not be amended except in written form, which is specifically approved or ratified by a majority vote of the Fund's Board, including a majority of independent Board members.

7.Confidentiality 

All reports and records prepared or maintained pursuant to the Code will be considered confidential and shall be maintained and protected accordingly. Except as otherwise required by law or the Code, such matters shall not be disclosed to anyone other than the appropriate Funds and their counsel, the appropriate Boards (or Committees) and their counsel and the Adviser. 

8.Internal Use

The Code is intended solely for the internal use by the Fund and does not constitute an admission, by or on behalf of the Fund, as to any fact, circumstance, or legal conclusion.
