DEFINED STRATEGY FUND INC. MARCH 31, 2006 A Discussion With Your Fund's Portfolio Manager We are pleased to provide you with this shareholder report for Defined Strategy Fund Inc. While the Fund is advised by IQ Investment Advisors LLC, the following discussion is provided by Nuveen Asset Management, the Fund's subadviser. How did the Fund perform during this period? For the six-month period ended March 31, 2006, the total investment return of Defined Strategy Fund Inc.'s Common Stock was +5.58%, based on a change in per share net asset value from $17.75 to $18.41. The Fund's unmanaged benchmark, the Dow Jones 10 Index (the "Index"), had a total return of +7.17% for the same period. The overall positive returns for the Index and the portfolio during the six-month period were driven by Merck & Co., Inc., JPMorgan Chase & Co., and AT&T, Inc., which were up 29.47%, 22.72%, and 12.81%, respectively, on a price basis. The laggard of the portfolio was General Motors Corp., down 30.51% on a price basis for the semi-annual period. In addition to investing in the 10 highest dividend-yielding stocks in the Dow Jones Industrial Average (SM) ("DJIA (SM)"), the Fund enters into variable prepaid forward contracts ("VPFs") with terms of approximately one year to sell liquid equity securities (the "Other Stocks"). The Other Stocks are a risk-controlled investment in a 15 to 20-stock portfolio designed to add alpha for the Fund. In exchange for a small upfront charge, the Fund participates in the potential price appreciation of the Other Stocks between 3.5% and 7.0%. A failure to appreciate 3.5% results in a loss of the upfront premium while an appreciation above 7.0% results in no extra benefit for the Fund. During the six-month period, the Other Stocks weighed on the portfolio's overall performance. For a description of the Fund's total investment return based on a change in per share market value of the Fund's Common Stock (as measured by the trading price of the Fund's shares on the New York Stock Exchange), and assuming reinvestment of dividends, please refer to the Financial Highlights section of this report. As a closed-end fund, the Fund's shares may trade in the secondary market at a premium or a discount to the Fund's net asset value. As a result, total investment returns based on changes in the market value of the Fund's Common Stock can vary significantly from total investment returns based on changes in the Fund's net asset value. Dow Jones Industrial Average and DJIA are service marks of Dow Jones & Company, Inc. Standard & Poor's 500, S&P 500, S&P SmallCap 600 and the S&P 100 Index are registered trademarks of the McGraw-Hill Companies. Describe the market environment during the six-month period. U.S. equities performed exceptionally well during the six-month period ended March 31, 2006, with the Standard & Poor's 500 (R) ("S&P 500 (R)") Index finishing March at 1,295, near the 52-week high of 1,307. The equity market demonstrated surprising resiliency as it bounced back from an unexpected low gross domestic product (GDP) for the fourth quarter of 2005 (actual 1.7% vs. expected 3.5%), lingering effects of Hurricanes Rita and Katrina, an inverted yield curve, moderately rising inflation, and initial signs of a slowing housing market. Further headwinds were provided by the 15th consecutive 0.25% increase in the target federal funds rate to 4.75% on March 28, 2006. The move was fully expected by the market, but the accompanying statement was highly anticipated as this was the first Federal Reserve Board statement under the new chairman, Ben S. Bernanke. The statement was in line with expectations or perhaps slightly more hawkish, ending with "further policy firming may be needed." On a positive note, strong consumer spending, higher corporate profits, robust employment, and favorable weather conditions during the first few months of 2006 were more than enough to drive the economy and equity markets higher. Economists' estimates indicate that GDP for the first quarter of 2006 grew at a 4.7% annualized rate, a full three-percentage point improvement over the previous three-month period, and approximately 0.5% ahead of the first quarter of 2005. DEFINED STRATEGY FUND INC. MARCH 31, 2006 For the three-month and 12-month periods ended March, 31 2006, the broad equity market, as represented by the S&P 500 Index, posted total returns of +4.21% and +11.73%, respectively. In spite of this impressive run, we continue to see value in the equity markets as the S&P 500 price/earnings (P/E) ratio at March 31, 2006 was 17.97, slightly below the 18.20 P/E ratio at September 30, 2005, and well below the 2-year and 5-year average P/E ratios of 19.50 and 29.10, respectively. Small cap stocks outperformed the broader market as the S&P SmallCap 600 (R) Index posted returns for the three-month and twelve-month periods ended March 31, 2006 of +12.84% and +24.07%, respectively. The performance of the equity markets' largest stocks, as represented by the S&P 100 (R) Index, lagged slightly during the three months and twelve months ended March 31, 2006 with total returns of just +3.67% and +6.85%, respectively. How have you managed the Fund during this period? Per the Fund's prospectus, the Fund has continued to invest substantially all of its assets in the ten highest dividend-yielding stocks in the DJIA. Trading activity during the fourth quarter of 2005 was driven by the annual rebalancing of the Dow Jones 10 Index and the Fund's annual repurchase offer for outstanding shares. Both events marginally impacted the portfolio as the Fund's underlying holdings in the Dow Jones 10 Index stocks had to be slightly readjusted on the Index reconstitution date, December 31, 2005. The actual names in the Index remained unchanged, but their respective weightings changed slightly to account for market gains and losses during 2005. The repurchase offer resulted in the repurchase of 25% of the Fund's outstanding shares and appropriate liquidity was maintained to accommodate the repurchase offer. In addition, during the fourth quarter of 2005, the Fund's original VPF contracts matured, resulting in the delivery of the Other Stocks to offset these positions. At the various expiration dates of the VPFs in the original portfolio, the Fund made its full economic gain on six of the fifteen Other Stocks and a partial gain on one. Eight of the fifteen Other Stock transactions expired out-of-the-money. As each VPF contract matured, a new Other Stock VPF contract was executed to maintain the Fund's economic exposure to the potential out-performance of the Other Stock portfolio. The fifteen VPF trades were replaced by a total of sixteen new trades. The new trades were structured so that in total 2% of the Fund's capital is at risk on the trades. The Fund will participate in the appreciation of the Other Stocks between approximately 4.0% and 7.0%. Any loss in the Other Stocks due to their potential decline is strictly limited by the risk control structure of the VPF trades. How would you characterize the Fund's position at the close of the period? We believe the Fund is well positioned to continue to meet its stated objectives. The indicative dividend yield on the Dow Jones 10 Index is +4.38% as compared to 1.76% indicative dividend yield of the S&P 500 Index. The current Other Stock portfolio is performing well, up on average 7.68% year-to- date as of March 31, 2006. Rob. A. Guttschow Portfolio Manager April 21, 2006 DEFINED STRATEGY FUND INC.

See Notes to Financial Statements. DEFINED STRATEGY FUND INC. MARCH 31, 2006 Notes to Financial Statements 1. Significant Accounting Policies: Defined Strategy Fund Inc. (the "Fund") is registered under the Investment Company Act of 1940, as amended, as a diversified, closed-end management investment company with a fixed term of existence. The Fund pursues its investment objective by investing substantially all of its net assets, in approximately equal amounts, in the ten highest dividend-yielding stocks in the Dow Jones Industrial Average (as of a date determined once each year) (the "Stocks"). To enhance its returns, the Fund will simultaneously enter into variable prepaid forward contracts, with terms of approximately one year, to sell liquid equity securities and will use the proceeds to purchase those same liquid equity securities other than the Stocks. The Fund's 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. These unaudited financial statements reflect all adjustments, which are, in opinion of management, necessary to present a fair statement of the results for the interim period. All such adjustments are of a normal, recurring nature. The Fund determines and makes available for publication the net asset value of its Common Stock on a daily basis. The Fund's Common Stock shares are listed on the New York Stock Exchange ("NYSE") under the symbol DSF. The following is a summary of significant accounting policies followed by the Fund. (a) Valuation of investments--Equity securities that are held by the Fund 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 Directors of the Fund. 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 Directors of the Fund. 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 and variable prepaid forward contracts 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. Valuation of other short-term vehicles is generally based on the net asset value of the underlying investment vehicle or amortized cost. Repurchase agreements are valued at cost plus accrued interest. The Fund employs pricing services to provide certain securities prices for the Fund. 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 Directors of the Fund, including valuations furnished by the pricing services retained by the Fund, which may use a matrix system for valuations. The procedures of a pricing service and its valuations are reviewed by the officers of the Fund under the general supervision of the Fund's Board of Directors. Such valuations and procedures will be reviewed periodically by the Board of Directors of the Fund. 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 NYSE. The values of such securities used in computing the net asset value of the Fund's shares 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 Fund's net asset value. 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 Fund's Board of Directors or by the Investment Adviser using a pricing service and/or procedures approved by the Fund's Board of Directors. DEFINED STRATEGY FUND INC. MARCH 31, 2006 Notes to Financial Statements (continued) (b) Derivative financial instruments--The Fund may engage in various portfolio investment strategies to increase the return of the Fund. Losses may arise due to changes in the value of the contract or if the counterparty does not perform under the contract. * Options--The Fund may purchase and write call and put options. When the Fund writes an option, an amount equal to the premium received by the Fund 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 Fund enters into a closing transaction), the Fund realizes a gain or loss on the option to the extent of the premiums received or paid (or 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. * Variable prepaid forward contracts--The Fund will enter into variable prepaid forward contracts with terms of approximately one year to sell liquid equity securities and will use the sale proceeds to purchase those same liquid equity securities. In a variable prepaid forward contract, the amount of shares (or their cash equivalent) that the seller is required to deliver at maturity varies as a function of the stock's performance. The variable prepaid forward contracts will be prepaid to the counterparties to these transactions and as a result the Fund will not be exposed to any risk that counterparties to these transactions will be unable to meet their obligations under the arrangements. The liquid equity securities may serve as collateral for the Fund's obligation under the variable prepaid forward contracts. * Financial futures contracts--The Fund may purchase or sell financial futures contracts and options on such futures contracts. 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 Fund deposits and maintains as collateral such initial margin as required by the exchange on which the transaction is effected. Pursuant to the contract, the Fund 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 Fund as unrealized gains or losses. When the contract is closed, the Fund 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. (c) Income taxes--It is the Fund's policy to comply with the requirements of the Internal Revenue Code applicable to regulated investment companies and to distribute substantially all of its taxable income to its shareholders. Therefore, no federal income tax provision is required. (d) 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. Interest income is recognized on the accrual basis. (e) Dividends and distributions--Dividends and distributions paid by the Fund are recorded on the ex-dividend dates. (f) Offering expenses--Direct expenses relating to the public offering of the Fund's Common Stock were charged to capital at the time of issuance of the shares. (g) Securities lending--The Fund 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 Fund and any additional required collateral is delivered to the Fund on the next business day. Where the Fund receives securities as collateral for the loaned securities, it collects a fee from the borrower. The Fund typically receives the income on the loaned securities but does not receive the income on the collateral. Where the Fund 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 Fund 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 Fund could experience delays and costs in gaining access to the collateral. The Fund 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.

In addition, IQ provides the necessary personnel, facilities, equipment and certain other services necessary to the operations of the Fund. For such services, the Fund will pay a monthly fee at an annual rate equal to .82% of the average daily value of the Fund's net assets plus borrowings for leverage and other investment purposes. IQ has entered into a Subadvisory Agreement with Nuveen Asset Management ("Nuveen") pursuant to which Nuveen provides certain investment advisory services to IQ with respect to the Fund. For such services, IQ will pay Nuveen a monthly fee at an annual rate equal to .35% of the average daily value of the Fund's net assets plus borrowings for leverage and other investment purposes. There was no increase in the aggregate fees paid by the Fund for these services.

Pursuant to that order, the Fund may retain Merrill Lynch Investment Managers, LLC ("MLIM, LLC"), an affiliate of IQ, 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 Fund, invest cash collateral received by the Fund for such loans, among other things, in a private investment company managed by MLIM, LLC or in registered money market funds advised by Merrill Lynch Investment Managers, L.P. ("MLIM"), an affiliate of IQ. Certain officers and/or directors of the Fund are officers and/or directors of IQ, ML & Co., MLIM, and/or MLIM, LLC.

MARCH 31, 2006 Fundamental Periodic Repurchase Policy The Board of Directors approved a fundamental policy whereby the Fund would adopt an "interval fund" structure pursuant to Rule 23c-3 under the Investment Company Act of 1940, as amended (the "1940 Act"). As an interval fund, the Fund will make annual repurchase offers at net asset value (less repurchase fee not to exceed 2%) to all Fund shareholders. The percentage of outstanding shares that the Fund can repurchase in each offer will be established by the Fund's Board of Directors shortly before the commencement of each offer, and will be between 5% and 25% of the Fund's then outstanding shares. The Fund has adopted the following fundamental policy regarding periodic repurchases: a) The Fund will make offers to repurchase its shares at annual (approximately 12-month) intervals pursuant to Rule 23c-3 under the 1940 Act ("Offers"). The Board of Directors may place such conditions and limitations on an Offer, as may be permitted under Rule 23c-3. b) The repurchase request deadline for each Offer, by which the Fund must receive repurchase requests submitted by shareholders in response to the most recent Offer, will be determined by reference to the Fund's initial repurchase request deadline of December 22, 2005, and thereafter upon the approximate anniversary date of the repurchase request deadline for the previous year (the "Repurchase Request Deadline"). c) The maximum number of days between a Repurchase Request Deadline and the next repurchase pricing date will be fourteen days; provided that if the fourteenth day after a Repurchase Request Deadline is not a business day, the repurchase pricing date shall be the next business day (the "Repurchase Pricing Date"). d) Offers may be suspended or postponed under certain circumstances, as provided for in Rule 23c-3. (For further details, see Note 4 to the Financial Statements.) Under the terms of the Offer for the most recent annual period, the Fund offered to purchase up to 1,876,309 shares from shareholders at an amount per share equal to the Fund's net asset value per share calculated as of the close of business of the New York Stock Exchange on January 5, 2006, eight business days after Thursday, December 22, 2005, the Repurchase Request Deadline. As of January 5, 2006, 1,876,309 shares, or 25% of the Fund's outstanding shares, were purchased by the Fund at $17.82 per share (subject to a repurchase fee of 0.10% of the net asset value per share); the Fund's net asset value per share was determined as of 4:00 p.m. EST, Thursday, January 5, 2006.
