JAY GERKEN, CFA CHAIRMAN, PRESIDENT AND CHIEF EXECUTIVE OFFICER DEAR SHAREHOLDER, Over the six month period ended April 30, 2004, most broad U.S. stock and bond market indexes posted moderate gains. Stocks generally continued to outpace bonds, with large-capitalization stocks typically outperforming small- and mid-cap stocks and international stock markets generally outperforming the domestic stock market. The economic environment was dominated by uncertainty surrounding the sustainability of the domestic economic recovery, a continued focus on new job growth and a geopolitical environment centering on news from Iraq and new acts of terrorism. Since the start of 2004, markets have been in a holding pattern -- volatility declined and returns were relatively muted. Equity markets seem to have priced in prospects of continued economic recovery and, in general, they were not disappointed. Both bond market and stock market participants were a bit unnerved by prospects for U.S. Federal Reserve Board ("Fed") tightening of key interest rates at some unknown future date, the continuing turmoil in Iraq, and the March 2004 bombings in Spain. Each of these elements had a negative influence on the stock market. Despite these concerns, however, - -------------------------------------------------------------------------------- PERFORMANCE SNAPSHOT AS OF APRIL 30, 2004 (EXCLUDING SALES CHARGES) - -------------------------------------------------------------------------------- 6 MONTHS - -------------------------------------------------------------------------------- Class A Shares -3.32% - -------------------------------------------------------------------------------- Russell 3000 Index 6.14% - -------------------------------------------------------------------------------- Goldman Sachs Technology Index -3.58% - -------------------------------------------------------------------------------- Lipper Science & Technology Funds Category Average -4.43% - -------------------------------------------------------------------------------- THE PERFORMANCE SHOWN REPRESENTS PAST PERFORMANCE.

So far this year, the economy overall has appeared to be growing at a pace similar to last year's rate. The ongoing recovery has been broad-based, with strength in the consumer sector, exports and business investments. Soaring corporate profit growth has led to vastly improved balance-sheet fundamentals in general, while highly stimulative monetary and fiscal policy continued to provide support, although the stimulative effects of fiscal policy could wane after tax-refund season ends this spring. Following a period of mixed employment news through the end of last year, job growth picked up substantially in the first calendar quarter of 2004. Signs of increasing inflation have begun to mount in recent weeks. Fiscal and monetary policymakers have been stimulating the economy since 2000. The Fed has more or less said it prefers inflation to deflation in the current environment. However, we believe the recent pick-up in inflationary signals has increased the possibility that the Fed may raise interest rates sooner than anticipated, perhaps as early as this summer. Accordingly, the recent debate in the market has focused on the timing and magnitude of prospective rate increases. PERFORMANCE REVIEW Within this environment, the fund performed as follows: For the six months ended April 30, 2004, Class A shares of the Smith Barney Technology Fund, excluding sales charges, returned -3.32%. In comparison, the fund's unmanaged benchmarks, the Russell 3000 Index(i) returned 6.14%, and the Goldman Sachs Technology Index ("GSTechnology Index")(ii) returned -3.58% for the same period. The fund's Lipper science & technology funds category average returned -4.43% for the same period.(1) The technology market moved upwards though November and December to end 2003 on a high note. The positive momentum continued into January, before falling through February, March, and April. The best performing sub-sectors were wireless equipment, IT services and internet, while semiconductors lagged. Telecom equipment stocks started 2004 well, as Ericsson and Andrew Corp. posted positive earnings results, and Verizon made constructive comments on their investment plans. However, it was not all positive news in the sector as NOKIA OYJ issued a profits warning as a result of losing market share and Nortel fired its CEO amid an accounting scandal. The semiconductor sub-sector also performed poorly, despite continued strong fundamentals. Semiconductor industry revenue was up more than 20% versus the previous year for each month of the period, but investors were becoming concerned that the growth rate could soon decelerate and have been cautious about high levels of inventory. Internet stalwarts Yahoo and EBAY INC. continued to power upwards, based on strong operating performance, and investor interest returned to the IT services sector, where data processing companies such as AUTOMATIC DATA PROCESSING, INC. and FIRST DATA CORP. had decent returns. FUND PERFORMANCE Although the fund's performance for the period was negative, it slightly outperformed its secondary benchmark, the GSTechnology Index. Positive performance was driven through positive stock selection within the software sub-sector, as well as by an underweight in semiconductors. The fund maintained a negative bias in semiconductors, which worked in our favor, and the holdings the fund did own, such as NVIDIA CORPORATION held up well. In software, fund holdings in AMDOCS LTD. and COMPUTER ASSOCIATES INTERNATIONAL, INC. performed well, as they continued to demonstrate strong operational performance with strong cash generation. Stock selection was mixed in computer hardware, where the fund was negatively affected by its ownership of SANMINA-SCI CORPORATION and SUN MICROSYSTEMS, INC. This was offset by fund holdings in APPLE COMPUTER, INC., which saw strong momentum from sales of its IPOD, and from LEXMARK, which was gaining market share in printers. In communications equipment, the fund also benefited from owning AVAYA INC. and MOTOROLA, INC., where restructuring efforts are bearing fruit. On the negative side, the fund's holding in Nokia hurt performance, which had poor results as it struggled with declining prices and market share loss for handsets. (1) Lipper, Inc. is a major independent mutual-fund tracking organization. Returns are based on the six-month period ended April 30, 2004, calculated among the 321 funds in the fund's Lipper category including the reinvestment of dividends and capital gains, if any, and excluding sales charges. 2 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report SPECIAL SHAREHOLDER NOTICE Effective April 29, 2004, Smith Barney Sector Series on behalf of the Smith Barney Technology Fund changed its primary performance benchmark from the Goldman Sachs Technology Index to the Russell 3000 Index. The Goldman Sachs Technology Index will continue as a secondary performance benchmark. Effective April 29, 2004, Smith Barney Class L shares were renamed Class C shares. On February 2, 2004, initial sales charges on these shares were eliminated. INFORMATION ABOUT YOUR FUND In recent months several issues in the mutual fund industry have come under the scrutiny of federal and state regulators. The fund's Adviser and some of its affiliates have received requests for information from various government regulators regarding market timing, late trading, fees and other mutual fund issues in connection with various investigations. The regulators appear to be examining, among other things, the fund's response to market timing and shareholder exchange activity, including compliance with prospectus disclosure related to these subjects. The fund has been informed that the Adviser and its affiliates are responding to those information requests, but are not in a position to predict the outcome of these requests and investigations. As always, thank you for your confidence in our stewardship of your assets. We look forward to helping you continue to meet your financial goals. Sincerely, /s/ R. Jay Gerken R. Jay Gerken, CFA Chairman, President and Chief Executive Officer MAY 18, 2004 The information provided is not intended to be a forecast of future events, a guarantee of future results or investment advice. Views expressed may differ from those of the firm as a whole. Portfolio holdings and breakdowns are as of April 30, 2004 and are subject to change and may not be representative of the portfolio manager's current or future investments. The fund's top ten holdings as of this date were: Microsoft Corp. (10.9%), Intel Corp. (10.7%), Cisco Systems Inc. (7.6%), Hewlett-Packard Co. (5.2%), International Business Machines Corp. (5.0%), Computer Associates International Inc. (3.8%), Oracle Corp. (3.4%), EMC Corp. (3.3%), Amdocs Ltd. (3.2%) and Lexmark International Inc. (3.1%). Please refer to pages 4 through 5 for a list and percentage breakdown of the fund's holdings. The mention of sector breakdowns is for informational purposes only and should not be construed as a recommendation to purchase or sell any securities. The information provided regarding such sectors is not a sufficient basis upon which to make an investment decision. Investors seeking financial advice regarding the appropriateness of investing in any securities or investment strategies discussed should consult their financial professional. Portfolio holdings are subject to change at any time and may not be representative of the portfolio manager's current or future investments.

The fund's portfolio composition is subject to change at any time. RISKS: In addition to normal risks associated with equity investing, narrowly focused investments typically exhibit higher volatility. The technology sector may be subject to greater governmental regulation, competitive pressures and rapid technological change and obsolescence, which may have a materially adverse effect on the sector. Additionally, the fund's performance will be influenced by political, social and economic factors affecting investments in companies in foreign countries not associated with domestic investing These risks are magnified in emerging markets. The securities of small- and mid-sized companies tend to be more volatile than those of larger companies. The fund may use derivatives, such as options and futures, which can be illiquid, may disproportionately increase losses, and have a potentially large impact on fund performance. All index performance reflects no deduction for fees, expenses or taxes. Please note that an investor cannot invest directly in an index.

Significant Accounting Policies The Smith Barney Technology Fund ("Fund"), a separate investment fund of the Smith Barney Sector Series Inc. ("Company"), a Maryland corporation, is registered under the Investment Company Act of 1940, as amended, as a non-diversified open-end management investment company. The Company consists of this Fund and two other separate investment funds: Smith Barney Financial Services Fund and Smith Barney Health Sciences Fund. The financial statements and financial highlights for the other funds are presented in separate shareholder reports. The following are significant accounting policies consistently followed by the Fund and are in conformity with generally accepted accounting principles ("GAAP"): (a) security transactions are accounted for on trade date; (b) securities traded on national securities markets are valued at the closing prices in the primary exchange on which they are traded; securities listed or traded on certain foreign exchanges or other markets whose operations are similar to the U.S. over-the-counter market (including securities listed on exchanges where the primary market is believed to be over-the-counter) and the securities for which no sale was reported on that date are valued at the mean between the bid and asked prices; securities which are listed or traded on more than one exchange or market are valued at the quotations on the exchange or market determined to be the primary market for such securities; securities listed on the NASDAQ National Market System for which market quotations are available are valued at the official closing price or, if there is no official closing price on that day, at the last sale price; (c) securities for which market quotations are not available will be valued in good faith at fair value by or under the direction of the Board of Directors; (d) securities maturing within 60 days are valued at cost plus accreted discount, or minus amortized premium, which approximates value; (e) the accounting records of the Fund are maintained in U.S. dollars. All assets and liabilities denominated in foreign currencies are translated into U.S. dollars based on the rate of exchange of such currencies against U.S. dollars on the date of valuation. Purchases and sales of securities, and income and expenses are translated at the rate of exchange quoted on the respective date that such transactions are recorded. Differences between income or expense amounts recorded and collected or paid are adjusted when reported by the custodian; (f) interest income, adjusted for amortization of premium and accretion of discount, is recorded on an accrual basis; (g) dividend income is recorded on the ex-dividend date; foreign dividends are recorded on the ex-dividend date or as soon as practical after the Fund determines the existence of a dividend declaration after exercising reasonable due diligence; (h) dividends and distributions to shareholders are recorded on the ex-dividend date; the Fund distributes dividends and capital gains, if any, at least annually; (i) gains or losses on the sale of securities are calculated by using the specific identification method; (j) class specific expenses are charged to each class; management fees and general fund expenses are allocated on the basis of relative net assets of each class or on another reasonable basis; (k) the character of income and gains to be distributed is determined in accordance with income tax regulations which may differ from U.S. generally accepted accounting principles; (l) the Fund intends to comply with the applicable provisions of the Internal Revenue Code of 1986, as amended, pertaining to regulated investment companies and to make distributions of taxable income sufficient to relieve it from substantially all Federal income and excise taxes; and (m) estimates and assumptions are required to be made regarding assets, liabilities and changes in net assets resulting from operations when financial statements are prepared. Changes in the economic environment, financial markets and any other parameters used in determining these estimates could cause actual results to differ. In addition, the Fund may enter into forward exchange contracts in order to hedge against foreign currency risk. These contracts are marked-to-market daily, by recognizing the difference between the contract exchange rate and the current market rate as an unrealized gain or loss. Realized gains or losses are recognized when contracts are settled or offset by entering into another forward exchange contract. The Fund may from time to time enter into options and/or futures contracts typically to hedge market or currency risk. 9 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report ================================================================================ NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) ================================================================================ 2.

In addition, Class A shares have a 1.00% CDSC, which applies if redemption occurs within one year from purchase payment. This CDSConly applies to those purchases of Class A shares which, when combined with current holdings of Class A shares, equal or exceed $1,000,000 in the aggregate. These purchases do not incur an initial sales charge. For the six months ended April 30, 2004, CGM and its affiliates received sales charges of approximately $20,000 and $9,000 on sales of the Fund's Class A and C shares, respectively. In addition, for the six months ended April 30, 2004, CDSCs paid to CGM and its affiliates were approximately: CLASS B CLASS C ================================================================================ CDSCs $50,000 $3,000 ================================================================================ For the six months ended April 30, 2004, CGM and its affiliates received brokerage commissions of $9,427. All officers and one Director of the Company are employees of Citigroup or its affiliates. 3. Investments During the six months ended April 30, 2004, the aggregate cost of purchases and proceeds from sales of investments (including maturities of long-term investments, but excluding short-term investments) were as follows: ================================================================================ Purchases $45,175,671 ================================================================================ Sales 51,617,125 ================================================================================ 10 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report ================================================================================ NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) ================================================================================ At April 30, 2004, the aggregate gross unrealized appreciation and depreciation of investments for Federal income tax purposes were substantially as follows: ================================================================================ Gross unrealized appreciation $ 6,732,937 Gross unrealized depreciation (5,953,428) ================================================================================ Net unrealized appreciation $ 779,509 ================================================================================ 4. Repurchase Agreements When entering into repurchase agreements, it is the Fund's policy that a custodian takes possession of the underlying collateral securities, the value of which at least equals the principal amount of the repurchase transaction, including accrued interest. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market to ensure the adequacy of the collateral. If the seller defaults and the value of the collateral declines or if bankruptcy proceedings are commenced with respect to the seller of the security, realization of the collateral by the Fund may be delayed or limited. 5. Concentration of Risk The Fund normally invests at least 80% of its assets in technology related investments. As a result of this concentration policy, the Fund's investments may be subject to greater risk and market fluctuation than a fund that invests in securities representing a broader range of investment alternatives. 6. Class Specific Expenses Pursuant to a Rule 12b-1 Distribution Plan, the Fund pays a service fee with respect to its Class A, B and C shares calculated at an annual rate of 0.25% of the average daily net assets of each respective class. In addition, the Fund also pays a distribution fee with respect to Class B and C shares calculated at an annual rate of 0.75% of the average daily net assets of each class, respectively. For the six months ended April 30, 2004, total Rule 12b-1 Distribution Plan fees, which are accrued daily and paid monthly, were as follows: CLASS A CLASS B CLASS C ================================================================================ Rule 12b-1 Distribution Plan Fees $35,086 $208,803 $165,212 ================================================================================ For the six months ended April 30, 2004, total Transfer Agency Service expenses were as follows: CLASS A CLASS B CLASS C ================================================================================ Transfer Agency Service Expenses $18,970 $28,280 $22,615 ================================================================================ For the six months ended April 30, 2004, total Shareholder Communication expenses were as follows: CLASS A CLASS B CLASS C ================================================================================ Shareholder Communication Expenses $9,306 $13,829 $10,899 ================================================================================ 7. Capital Shares At April 30, 2004, the Fund had 800 million shares of capital stock authorized with a par value of $0.001 per share. The Fund has the ability to issue multiple classes of shares. Each share of a class represents an identical interest in the Fund and has the same rights, except that each class bears certain expenses specifically related to the distribution of its shares. Effective April 29, 2004, the Fund renamed Class L shares as Class C shares. 11 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report ==================================================================================================================================== NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) ==================================================================================================================================== Transactions in shares of each class were as follows: SIX MONTHS ENDED YEAR ENDED APRIL 30, 2004 OCTOBER 31, 2003 ----------------------------- ------------------------------ SHARES AMOUNT SHARES AMOUNT ==================================================================================================================================== CLASS A Shares sold 1,115,186 $ 4,600,835 1,873,768 $ 6,063,645 Shares reacquired (1,146,014) (4,659,478) (1,395,233) (4,488,352) - ------------------------------------------------------------------------------------------------------------------------------------ Net Increase (Decrease) (30,828) $ (58,643) 478,535 $ 1,575,293 ==================================================================================================================================== CLASS B Shares sold 634,957 $ 2,502,242 2,010,147 $ 6,240,032 Shares reacquired (1,383,590) (5,484,205) (1,866,876) (5,798,567) - ------------------------------------------------------------------------------------------------------------------------------------ Net Increase (Decrease) (748,633) $(2,981,963) 143,271 $ 441,465 ==================================================================================================================================== CLASS C+ Shares sold 2,235,676 $ 8,710,683 1,813,427 $ 6,260,452 Shares reacquired (3,613,690) (14,419,009) (1,661,743) (5,153,092) - ------------------------------------------------------------------------------------------------------------------------------------ Net Increase (Decrease) (1,378,014) $(5,708,326) 151,684 $ 1,107,360 ==================================================================================================================================== + ON APRIL 29, 2004, CLASS L SHARES WERE RENAMED AS CLASS C SHARES. 8. Additional Information The Fund has received the following information from Citigroup Asset Management ("CAM"), the Citigroup business unit which includes the Fund's Investment Manager and other investment advisory companies, all of which are indirect, wholly-owned subsidiaries of Citigroup. CAM is reviewing its entry, through an affiliate, into the transfer agent business in the period 1997-1999. As CAM currently understands the facts, at the time CAM decided to enter the transfer agent business, CAM sub-contracted for a period of five years certain of the transfer agency services to a third party and also concluded a revenue guarantee agreement with this sub-contractor providing that the sub-contractor would guarantee certain benefits to CAM or its affiliates (the "Revenue Guarantee Agreement"). In connection with the subsequent purchase of the sub-contractor's business by an affiliate of the current sub-transfer agent (PFPC Inc.) used by CAM on many of the funds it manages, this Revenue Guarantee Agreement was amended eliminating those benefits in exchange for arrangements that included a one-time payment from the sub-contractor. The Boards of CAM-managed funds (the "Boards") were not informed of the Revenue Guarantee Agreement with the sub-contractor at the time the Boards considered and approved the transfer agent arrangements. Nor were the Boards informed of the subsequent amendment to the Revenue Guarantee Agreement when that occurred. CAM has begun to take corrective actions. CAM will pay to the applicable funds approximately $17 million (plus interest) that CAM and its affiliates received from the Revenue Guarantee Agreement and its amendment. CAM also plans an independent review to verify that the transfer agency fees charged by CAM were fairly priced as compared to competitive alternatives. CAM is instituting new procedures and making changes designed to ensure no similar arrangements are entered into in the future. CAM has briefed the SEC, the New York State Attorney General and other regulators with respect to this matter, as well as the U.S. Attorney who is investigating the matter. CAM is cooperating with governmental authorities on this matter, the ultimate outcome of which is not yet determinable. 12 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report ================================================================================ NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED) ================================================================================ 9. Legal Matters Class action lawsuits have been filed against Citigroup Global Markets Inc. (the "Distributor") and a number of its affiliates, including Smith Barney Fund Management LLC and Salomon Brothers Asset Management Inc (the "Advisers"), substantially all of the mutual funds managed by the Advisers (the "Funds"), and directors or trustees of the Funds. The complaints allege, among other things, that the Distributor created various undisclosed incentives for its brokers to sell Smith Barney and Salomon Brothers funds. In addition, according to the complaints, the Advisers caused the Funds to pay excessive brokerage commissions to the Distributor for steering clients towards proprietary funds. The complaints also allege that the defendants breached their fiduciary duty to the Funds by improperly charging Rule 12b-1 fees and by drawing on Fund assets to make undisclosed payments of soft dollars and excessive brokerage commissions. The complaints seek injunctive relief and compensatory and punitive damages, rescission of the Funds' contracts with the Advisers, recovery of all fees paid to the Advisers pursuant to such contracts and an award of attorneys' fees and litigation expenses. Citigroup Asset Management believes that the suits are without merit and intends to defend the cases vigorously. Additional lawsuits arising out of these circumstances and presenting similar allegations and requests for relief may be filed against the defendants in the future. Neither Citigroup Asset Management nor the Funds believe that any of the pending actions will have a material adverse effect on the Funds or the ability of the Distributor or the Advisers to perform under their respective contracts with the Funds. 13 SMITH BARNEY SECTOR SERIES INC. | 2004 Semi-Annual Report ==================================================================================================================================== FINANCIAL HIGHLIGHTS ==================================================================================================================================== FOR A SHARE OF EACH CLASS OF CAPITAL STOCK OUTSTANDING THROUGHOUT EACH YEAR ENDED OCTOBER 31, UNLESS OTHERWISE NOTED: CLASS A SHARES 2004(1)(2) 2003(2) 2002(2) 2001 2000(3) ==================================================================================================================================== NET ASSET VALUE, BEGINNING OF PERIOD $ 3.92 $ 2.78 $ 4.21 $ 9.14 $11.40 - ------------------------------------------------------------------------------------------------------------------------------------ INCOME (LOSS) FROM OPERATIONS: Net investment loss(4) (0.02) (0.04) (0.05) (0.08) (0.07) Net realized and unrealized gain (loss) (0.11) 1.18 (1.38) (4.85) (2.19) - ------------------------------------------------------------------------------------------------------------------------------------ Total Income (Loss) From Operations (0.13) 1.14 (1.43) (4.93) (2.26) - ------------------------------------------------------------------------------------------------------------------------------------ NET ASSET VALUE, END OF PERIOD $ 3.79 $ 3.92 $ 2.78 $ 4.21 $ 9.14 - ------------------------------------------------------------------------------------------------------------------------------------ TOTAL RETURN(5) (3.32)%++ 41.01% (33.97)% (53.94)% (19.82)%++ - ------------------------------------------------------------------------------------------------------------------------------------ NET ASSETS, END OF PERIOD (000s) $25,907 $26,946 $17,754 $27,058 $46,363 - ------------------------------------------------------------------------------------------------------------------------------------ RATIOS TO AVERAGE NET ASSETS: Expenses(4)(6) 1.47%+ 1.50% 1.50% 1.50% 1.52%+ Net investment loss (1.04)+ (1.09) (1.29) (1.31) (1.31)+ - ------------------------------------------------------------------------------------------------------------------------------------ PORTFOLIO TURNOVER RATE 45% 54% 76% 62% 24% ==================================================================================================================================== (1) FOR THE SIX MONTHS ENDED APRIL 30, 2004 (UNAUDITED).
