Doll, Jr., Chief Executive Officer, Master Enhanced S&P 500 Series of Quantitative Master Series Trust, 800 Scudders Mill Road, Plainsboro, NJ 08536. Mailing address: P.O. Box 9011, Princeton, NJ 08543-9011 Registrant's telephone number, including area code: (609) 282-2800 Date of fiscal year end: 12/31/05 Date of reporting period: 01/01/05 - 12/31/05 Item 1 - Report to Stockholders Master Enhanced S&P 500 Series Annual Report, December 31, 2005 A Discussion With Your Fund's Portfolio Manager Amid a volatile investing environment, Master Enhanced S&P 500 Series managed to outpace the return of the Standard & Poor's 500 Index for the year. How did the portfolio perform during the fiscal year in light of the existing market conditions? For the 12-month period ended December 31, 2005, Master Enhanced S&P 500 Series had a net total return of +5.66% (master level). For the same period, the Standard & Poor's 500 (S&P 500) Index returned +4.91%. Performance benefited from both our stock-selection and stock substitution strategies. The U.S. equity markets exhibited substantial volatility over the 12-month period, moving sideways for much of the year. The period got off to a rough start after a very strong fourth quarter of 2004. Economically sensitive and small-capitalization stocks fared the worst out of the gate. January 2005 was characterized by mixed economic data, higher interest rates, disappointing corporate earnings reports and climbing oil prices. In February, the market reversed course and performed well, even as productivity growth slowed and oil prices continued to climb. By March, however, stock prices resumed their downward slide, hurt by a combination of a worse-than-expected trade deficit, mixed economic news, continued high oil prices and rising interest rates. 1 In April, retail sales, payroll data, and consumer and business sentiment weakened. For most of the month, equity markets were dogged by continuing inflationary concerns, particularly as the price of oil climbed above $57 per barrel. The month closed with the release of March data indicating a particularly large jump in the Consumer Price Index, which worried investors concerned about the prospect of higher interest rates. May brought the announcement of slower-than-expected economic growth (with 3.1% gross domestic product growth in the first quarter). But despite concerns about slower economic activity, decelerating corporate profit growth and high oil prices, first-quarter earnings reports remained strong, leading to a stock market rally. June, however, brought a slowdown in the equity market as further worries about a slower economy dampened markets. July was an impressive month for equity performance. The market was able to overcome the drag provided by a strong dollar, higher energy prices and a major terrorist attack in London. That attack caused an immediate 4% drop in the S&P 500 Index. However, investors quickly rebounded, and the market losses were recovered only one day later. August brought another reversal, as higher oil prices continued to engender fears of economic weakness. In the aftermath of Hurricane Katrina, the price of oil reached $70 per barrel. The market turned slightly positive in September as improved profits in the energy sector offset weakness in the retail, transportation, tourism and insurance sectors. Stock prices slid again in October amid continued signs of a slower economy and renewed concerns about inflation. Despite economic growth of 4.1% for the third quarter of 2005, short-term interest rates rose, oil prices remained historically high and consumer 2 confidence declined. In November, equities were resilient in the face of further interest rate hikes, high energy prices and the strength of the U.S. dollar, which cut into the profits of domestic companies that do business internationally. Stock values rebounded as companies' strong productivity and high profit margins led to solid earnings growth, and as oil prices fell to the mid-$50 per barrel range. After nearly six weeks of stock market gains, equity performance was uninspiring in December, with thin trading volumes causing volatile movements in stock prices. Compounding the mixed results and leaving investors uncertain about the direction of the economy in 2006 was the fact that the yield curve inverted between the two-year and 10-year sectors at the end of December. That is, 10-year bond yields fell below two-year yields. Such inversions are historically a harbinger of an economic downturn. For the full year, the S&P 500 Index's +4.91% return lagged the +12.56% return of the S&P MidCap 400 Index and the +7.68% return of the S&P SmallCap 600 Index. As expected, interest rates moved considerably during the period as the yield curve flattened. The Federal Reserve continued its "measured" pace of monetary tightening by raising the federal funds rate in 25 basis point increments eight times in 2005. This brought the target short-term interest rate to 4.25% by year-end. What changes were made to the portfolio during the period? Throughout the period, as changes were made to the composition of the S&P 500 Index, we purchased and sold securities to maintain the Series' objective of tracking the risks and return of the benchmark. 3 During the year, the S&P 500 made the transition to a "free-float" or "float-adjusted" methodology for calculating market capitalization. The transition occurred in two phases taking place in March and then in September. With the change, only the shares of company stock that are readily available in the public market are used to calculate a company's market capitalization. Float adjustment excludes shares that are closely held by other publicly traded companies, control groups (majority shareholders retaining their majority) or government agencies. Accordingly, the number of shares used to make index calculations reflect only those shares that actually are available to investors, not all of a company's outstanding shares. The value of a float-adjusted index more accurately reflects the combined market value of companies available for public trading. To maintain a tight tracking to the benchmark, we adjusted the portfolio to be in line with the revised composition of the Index. We continued to use our quantitative stock selection and stock substitution strategies in an effort to generate returns above those offered by the Index. The goal of our stock selection process is to use quantitative techniques to determine whether a stock might outperform or underperform the market. We analyze each security by using quantitative screens that provide signals that ultimately inform our investment decisions. These signals may include earnings quality, valuations, earnings surprises, additional equity issuance, short interest and price momentum factors, among others. We also apply stock substitution strategies opportunistically as a value-added trading strategy. Our goal is to take advantage of temporary price strength in a security that might 4 result from a corporate acquisition, corporate restructuring or index composition change. We also might employ convertible bond substitution when opportunities exist, taking a position in a company's convertible securities -- bonds that can be exchanged for shares of stock, in certain situations -- as a cheaper alternative to buying its equity shares. In November, we removed the portfolio's earnings surprise/earnings estimate revision and positive price momentum signals, and instead established our turn-of-the-year positions, which we intend to maintain through the first half of January. The earnings surprise/earnings estimate revision signal will remain off until the second quarter of 2006. How would you characterize the portfolio's position at the close of the period? We believe the portfolio remains positioned to match the risk characteristics of its benchmark, regardless of the direction the market takes. Vincent J.

Significant Accounting Policies: Master Enhanced S&P 500 Series (the "Series"), a non-diversified investment company, is part of Quantitative Master Series Trust (the "Trust"). The Trust is registered under the Investment Company Act of 1940, as amended, and is organized as a Delaware statutory trust. The Declaration of Trust permits the Trustees to issue nontransferable interest in the Series, subject to certain limitations. The Series' financial statements are prepared in conformity with U.S. generally accepted accounting principles, which may require the use of management accruals and estimates. Actual results may differ from these estimates. The following is a summary of significant accounting policies followed by the Series. (a) Valuation of investments - Equity securities that are held by the Series that are traded on stock exchanges or the Nasdaq National Market are valued at the last sale price or official close price on the exchange, as of the close of business on the day the securities are being valued or, lacking any sales, at the last available bid price for long positions, and at the last available asked price for short positions. In cases where equity securities are traded on more than one exchange, the securities are valued on the exchange designated as the primary market by or under the authority of the Board of Trustees of the Trust. Long positions traded in the over-the-counter ("OTC") market, Nasdaq Small Cap or Bulletin Board are valued at the last available bid price or yield equivalent obtained from one or more dealers or pricing services approved by the Board of Trustees of the Trust. Short positions traded in the OTC market are valued at the last available asked price. Portfolio securities that are traded both in the OTC market and on a stock exchange are valued according to the broadest and most representative market. Options written are valued at the last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last asked price. Options purchased are valued at their last sale price in the case of exchange-traded options or, in the case of options traded in the OTC market, the last bid price. Swap agreements are valued based upon quoted fair valuations received daily by the Fund from a pricing service or counterparty. Financial futures contracts and options thereon, which are traded on exchanges, are valued at their last sale price as of the close of such exchanges. Obligations with remaining maturities of 60 days or less are valued at amortized cost unless the Investment Adviser believes that this method no longer produces fair valuations. Repurchase agreements are valued at cost plus accrued interest. The Series employs pricing services to provide certain securities prices for the Series. Securities and assets for which market quotations are not readily available are valued at fair value as determined in good faith by or under the direction of the Board of Trustees of the Trust, including valuations furnished by the pricing services retained by the Series, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Trust under the general supervision of the Trust's Board of Trustees. Such valuations and procedures will be reviewed periodically by the Board of Trustees of the Trust. Generally, trading in foreign securities, as well as U.S. government securities, money market instruments and certain fixed income securities is substantially completed each day at various times prior to the close of business on the New York Stock Exchange ("NYSE"). The values of such securities used in computing the net assets of the Series are determined as of such times. Foreign currency exchange rates also are generally determined prior to the close of business on the NYSE. Occasionally, events affecting the values of such securities and such exchange rates may occur between the times at which they are determined and the close of business on the NYSE that may not be reflected in the computation of the Series' net assets. If events (for example, a company announcement, market volatility or a natural disaster) occur during such periods that are expected to materially affect the value of such securities, those securities may be valued at their fair value as determined in good faith by the Trust's Board of Trustees or by the Investment Adviser using a pricing service and/or procedures approved by the Trust's Board of Trustees. 22 NOTES TO FINANCIAL STATEMENTS (continued) (b) Derivative financial instruments - The Series may engage in various portfolio investment strategies to provide liquidity or as a proxy for a direct investment in securities underlying the Series' index. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. o Financial futures contracts - The Series may purchase or sell financial futures contracts and options on such futures contracts as a proxy for a direct investment in securities underlying the Series' index. Futures contracts are contracts for delayed delivery of securities at a specific future date and at a specific price or yield. Upon entering into a contract, the Series deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Series agrees to receive from or pay to the broker an amount of cash equal to the daily fluctuation in value of the contract. Such receipts or payments are known as variation margin and are recorded by the Series as unrealized gains or losses. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. o Swaps - The Series may enter into swap agreements, which are over-the-counter contracts in which the Series and a counterparty agree to make periodic net payments on a specified notional amount. The net payments can be made for a set period of time or may be triggered by a predetermined credit event. The net periodic payments may be based on a fixed or variable interest rate; the change in market value of a specified security, basket of securities, or index; or the return generated by a security. These periodic payments received or made by the Series are recorded in the accompanying Statement of Operations as realized gains or losses, respectively. Gains or losses are also realized upon termination of the swap agreements. Swaps are marked-to-market daily and changes in value are recorded as unrealized appreciation (depreciation). Risks include changes in the returns of the underlying instruments, failure of the counterparties to perform under the contracts' terms and the possible lack of liquidity with respect to the swap agreements. o Options - The Series may purchase and write covered call and put options. When the Series writes an option, an amount equal to the premium received by the Series is reflected as an asset and an equivalent liability. The amount of the liability is subsequently marked-to-market to reflect the current market value of the option written. When a security is purchased or sold through an exercise of an option, the related premium paid (or received) is added to (or deducted from) the basis of the security acquired or deducted from (or added to) the proceeds of the security sold. When an option expires (or the Series enters into a closing transaction), the Series realizes a gain or loss on the option to the extent of the premiums received or paid (or a gain or loss to the extent the cost of the closing transaction exceeds the premium paid or received). Written and purchased options are non-income producing investments. o Forward foreign exchange contracts - The Series may enter into forward foreign exchange contracts as a hedge against either specific transactions or portfolio positions. The contract is marked-to-market daily and the change in market value is recorded by the Series as an unrealized gain or loss. When the contract is closed, the Series records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. o Foreign currency options and futures - The Series may also purchase or sell listed or over-the-counter foreign currency options, foreign currency futures and related options on foreign currency futures as a short or long hedge against possible variations in foreign exchange rates. Such transactions may be effected with respect to hedges on non-U.S. dollar-denominated securities owned by the Series, sold by the Series but not yet delivered, or committed or anticipated to be purchased by the Series. 23 NOTES TO FINANCIAL STATEMENTS (continued) (c) Foreign currency transactions - Transactions denominated in foreign currencies are recorded at the exchange rate prevailing when recognized. Assets and liabilities denominated in foreign currencies are valued at the exchange rate at the end of the period. Foreign currency transactions are the result of settling (realized) or valuing (unrealized) assets or liabilities expressed in foreign currencies into U.S. dollars. Realized and unrealized gains or losses from investments include the effects of foreign exchange rates on investments. The Fund invests in foreign securities, which may involve a number of risk factors and special considerations not present with investments in securities of U.S. corporations. (d) Income taxes - The Series is classified as a partnership for federal income tax purposes. As such, each investor in the Series is treated as owner of its proportionate share of the net assets, income, expenses and realized and unrealized gains and losses of the Series. Therefore, no federal income tax provision is required. Under the applicable foreign tax law, a withholding tax may be imposed on interest, dividends and capital gains at various rates. It is intended that the Series' assets will be managed so an investor in the Series can satisfy the requirements of Subchapter M of the Internal Revenue Code. (e) Security transactions and investment income - Security transactions are recorded on the dates the transactions are entered into (the trade dates). Realized gains and losses on security transactions are determined on the identified cost basis. Dividend income is recorded on the ex-dividend dates. Dividends from foreign securities where the ex-dividend date may have passed are subsequently recorded when the Series has determined the ex-dividend date. Interest income is recognized on the accrual basis. (f) Securities lending - The Series may lend securities to financial institutions that provide cash or securities issued or guaranteed by the U.S. government as collateral, which will be maintained at all times in an amount equal to at least 100% of the current market value of the loaned securities. The market value of the loaned securities is determined at the close of business of the Series and any additional required collateral is delivered to the Series on the next business day. Where the Series receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Series typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Series receives cash collateral, it may invest such collateral and retain the amount earned on such investment, net of any amount rebated to the borrower. Loans of securities are terminable at any time and the borrower, after notice, is required to return borrowed securities within five business days. The Series may pay reasonable finder's, lending agent, administrative and custodial fees in connection with its loans. In the event that the borrower defaults on its obligation to return borrowed securities because of insolvency or for any other reason, the Series could experience delays and costs in gaining access to the collateral. The Series also could suffer a loss where the value of the collateral falls below the market value of the borrowed securities, in the event of borrower default or in the event of losses on investments made with cash collateral. 2. Investment Advisory Agreement and Transactions with Affiliates: The Trust has entered into an Investment Advisory Agreement with Fund Asset Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc. ("PSI"), an indirect, wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML & Co."), which is the limited partner. FAM is responsible for the management of the Series' portfolio and provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Series. For such services, the Series pays a monthly fee at an annual rate of .01% of the Series' average daily net assets. 24 NOTES TO FINANCIAL STATEMENTS (continued) The Trust has received an exemptive order from the Securities and Exchange Commission permitting it to lend portfolio securities to Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S"), an affiliate of FAM, or its affiliates. As of December 31, 2005, the Series lent securities with a value of $5,297,290 to MLPF&S or its affiliates. Pursuant to that order, the Trust also has retained Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of FAM, as the securities lending agent for a fee based on a share of the returns on investment of cash collateral. MLIM, LLC may, on behalf of the Trust and the Series, invest cash collateral received by the Series for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by FAM or its affiliates. For the year ended December 31, 2005, MLIM, LLC received $7,504 in securities lending agent fees from the Series. For the year ended December 31, 2005, the Series reimbursed FAM $15,455 for certain accounting services. In addition, MLPF&S received $5,931 in commissions on the execution of portfolio security transactions for the Series for the year ended December 31, 2005. Certain officers and/or trustees of the Trust are officers and/or directors of FAM, PSI, ML & Co., and/or MLIM, LLC. 3. Investments: Purchases and sales of investments, excluding short-term securities, for the year ended December 31, 2005 were $964,716,235 and $836,002,215, respectively. Transactions in call options written for the year ended December 31, 2005 were as follows: - ------------------------------------------------------------------------------- Number of Premiums Call Options Written Contracts Received - ------------------------------------------------------------------------------- Outstanding call options written, beginning of year .......................... -- -- Options written .............................. 1,285 $ 48,804 Options expired ..............................

Short-Term Borrowings: The Trust, on behalf of the Series, along with certain other funds managed by FAM and its affiliates, is a party to a $500,000,000 credit agreement with a group of lenders. The Series may borrow under the credit agreement to fund shareholder redemptions and for other lawful purposes other than for leverage. The Series may borrow up to the maximum amount allowable under the Series' current prospectus and statement of additional information, subject to various other legal, regulatory or contractual limits. The Series pays a commitment fee of .07% per annum based on the Series' pro rata share of the unused portion of the credit agreement. Amounts borrowed under the credit agreement bear interest at a rate equal to, at each Series' election, the federal funds rate plus .50% or a base rate as defined in the credit agreement. The Series did not borrow under the credit agreement during the year ended December 31, 2005. On November 23, 2005 the credit agreement was renewed for one year under substantially the same terms. 26 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Investors and Board of Trustees of Quantitative Master Series Trust: We have audited the accompanying statement of assets and liabilities, including the schedule of investments, of Master Enhanced S&P 500 Series, one of the portfolios constituting the Quantitative Master Series Trust (the "Trust"), as of December 31, 2005, and the related statement of operations for the year then ended, the statements 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 Trust'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. The Trust is not required to have, nor were we engaged to perform, an audit of its 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 Trust's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. Our procedures included confirmation of securities owned as of December 31, 2005, by correspondence with the custodian and brokers; where replies were not received from brokers, we performed other auditing procedures. 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 Master Enhanced S&P 500 Series of the Quantitative Master Series Trust as of December 31, 2005, 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 its financial highlights for each of the five years in the period then ended, in conformity with U.S. generally accepted accounting principles.
