R. Jay Gerken, CFA
Chairman, President and
Chief Executive Officer

Dear Shareholder,
Over the twelve-months 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 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, the underlying economic and financial
fundamentals continued to improve through the end of the period.

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 investment. 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, 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.

Please read on for a more detailed look at prevailing economic and market
conditions during the fund's fiscal year and to learn how those conditions and
changes made to the portfolio during this time may have affected fund
performance.

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.

     2 Smith Barney Multiple Discipline Funds -- All Cap Growth and Value
                           Fund | 2004 Annual Report




                               MANAGER OVERVIEW

Special Shareholder Notice
On January 21, 2004, many changes took place affecting the fund's name,
investment strategy, portfolio management team and performance benchmarks. The
fund's name changed from Smith Barney Premier Selections All Cap Growth Fund to
Smith Barney Multiple Discipline Funds -- All Cap Growth and Value Fund. In
addition, the new target allocations are 50% to an All Cap Growth segment and
50% to an All Cap Value segment. Alan J. Blake and Richard Freeman co-manage
the All Cap Growth segment, and John Goode and Peter J. Hable co-manage the All
Cap Value segment. The fund is coordinated by overlay portfolio managers who
purchase and sell securities for the fund on the basis of recommendations
received from each segment's portfolio managers. These overlay portfolio
managers essentially utilize the underlying recommendations of the segment
managers in a manner that is appropriate for the fund. For instance, they
identify and analyze duplicate positions that may occur if different segment
managers recommend the same security for their respective segment, and they
determine whether the size of each position is appropriate for the fund. Upon
consultation with a fund's segment managers, the overlay portfolio managers may
make adjustments if one or more segments become over- or underweighted as a
result of market appreciation or depreciation. The overlay portfolio managers
of the fund are Roger Paradiso and Kirstin Mobyed. Lastly, the fund's benchmark
was changed from the Russell 1000 Growth Index, Russell 2000 Growth Index and
the S&P MidCap 400 Index to the Russell 3000 Index.

In addition, 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.

Market Overview
With monetary and fiscal policy more stimulative now than at any time in the
recent past, the economy strengthened over the last 12 months. In general,
equity markets were buoyant even thought they experienced a

mild correction in March and April, perhaps due to extended valuations in some
sectors. Nevertheless, it is important to note that after three consecutive
calendar years of negative returns (2000-2002) followed by one positive year,
the markets are returning to historic positive trend lines.

Performance Review
For the 12 months ended April 30, 2004, Class A shares of the Smith Barney
Multiple Discipline Funds -- All Cap Growth and Value Fund, excluding sales
charges, returned 25.95%. These shares performed approximately in line with the
fund's new unmanaged benchmark, the Russell 3000 Index,/i/ which returned
25.11% for the same period. The previous benchmarks, the Russell 1000 Growth
Index,/ii/ Russell 2000 Growth Index/iii/ and the S&P Mid Cap 400 Index/iv/
returned 21.65%, 41.57% and 34.45%, respectively. The fund also performed
approximately in line with its Lipper multi-cap growth funds category average,
which returned 25.39% for the same period./1 /

Factors that Affected Fund Performance
The fund's performance during the period was fueled by positive returns from a
number of holdings in a range of sectors, including the consumer staples,
energy, telecommunication service and utilities sectors. Sectors that detracted
from overall performance included the consumer discretionary, financial,
healthcare, information technology, industrial, and materials sectors.

Consumer staples stocks contributed positively overall to returns as earnings
growth of companies such as The Gillette Co. and PepsiCo, Inc. benefited from
the continued strength in consumer spending and by a weaker U.S. dollar, which
helped boost sales in overseas markets. The energy sector contributed
positively overall to the performance of the portfolio during the period.
Earnings growth of companies such as BP PLC and Exxon Mobil Corp. continued to
improve as the price of oil increased during the period.

Investments that detracted from performance included information technology,
including stocks such as Intel Corp. and Texas Instruments Inc. We continue to
believe that there is a broad-based recovery under way in network technology
spending in these stocks. Additionally, the consumer services sector negatively
impacted the performance of the portfolio as investors focusing on the
lackluster growth in the labor market grew increasingly concerned about the
sustainability of consumer spending. We continued to add strategically to
positions in this sector because we believe that accelerating job growth will
support consumer spending in months ahead.

Our positions in some financials, such as Berkshire Hathaway Inc. and Merrill
Lynch & Co., detracted from performance. Weakness in this sector was due in
part to investors focusing on the direction of interest rates and a growing
concern regarding the sustainable long-term growth of the economy. We continued
to add to our position in Merrill Lynch and increased our weighting in the
brokerage industry based on current market valuations and prospects we see for
stronger earnings growth.

Thank you for your investment in the Smith Barney Multiple Discipline Funds --
All Cap Growth and Value Fund. We appreciate that you have entrusted us to
manage your money and value our relationship with you.

  weighted total return index which is comprised of 1,000 of some of the
  larger-capitalized U.S.-domiciled companies whose common stock is traded in
  the United States on the New York Stock Exchange, American Stock Exchange and
  NASDAQ National Market. The Russell 2000 Growth Index is a capitalization
  weighted total return index which is compromised of 2,000 of the smallest
  capitalized U.S. domiciled companies with less than average growth
  orientation whose common stock is traded in the United States on the New York
  Stock Exchange, American Stock Exchange and NASDAQ National Market. The S&P
  MidCap 400 Index is a widely recognized index of 400 medium-capitalization
  stocks. The Russell 3000 Index measures the performance of the 3,000 largest
  U.S. companies based on total market capitalization, which represent
  approximately 98% of the U.S. equity market. Figures for the Russell 1000
  Growth, Russell 2000 Growth, S&P MidCap 400 and Russell 3000 Indices include
  the reinvestment of dividends. The Indexes are unmanaged and are not subject
  to the same management and trading expenses as a mutual fund. Please note
  that an investor cannot invest directly in an index.
++It is the opinion of management that the Russell 3000 Index more accurately
  reflects the current composition of the Fund than the Russell 1000 Growth
  Index, Russell 2000 Growth and the S&P MidCap 400 Index. In future reports,
  the Russell 3000 Index will be used as the basis of comparison of total
  returns for all periods shown.

  All figures represent past performance and are not a guarantee of future
  results. Investment return and principal value of an investment will
  fluctuate so that an investor's shares, when redeemed, may be worth more or
  less than their original cost. The returns shown do not reflect the deduction
  of taxes that a shareholder would pay on fund distributions or the redemption
  of fund shares.

                           Fund | 2004 Annual Report




 NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies

The Smith Barney Multiple Discipline Funds -- All Cap Growth and Value Fund
("Fund"), (formerly known as Smith Barney Premier Selections All Cap Growth
Fund), a separate diversified investment fund of the Smith Barney Investment
Funds Inc. ("Company"), a Maryland corporation, is registered under the
Investment Company Act of 1940, as amended, as an open-end management
investment company. The Company consists of this Fund and eight other separate
investment funds: Smith Barney Investment Grade Bond Fund, Smith Barney
Government Securities Fund, Smith Barney Small Cap Growth Fund, Smith Barney
Small Cap Value Fund, Smith Barney Hansberger Global Value Fund, Smith Barney
Multiple Discipline Funds -- Large Cap Growth and Value Fund (formerly known as
Smith Barney Premier Selections Large Cap Fund), Smith Barney Multiple
Discipline Funds -- Global All Cap Growth and Value Fund (formerly known as
Smith Barney Premier Selections Global Growth Fund) and Smith Barney Group
Spectrum 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 on such markets or, in the absence of sales, at the mean between the
closing bid and asked prices; over-the-counter securities are valued at the
mean between the bid and asked prices; 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) dividend income is recorded on the ex-dividend date and interest
income is recorded on an accrual basis; foreign dividend income is 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;
(f ) gains or losses on the sale of securities are calculated by using the
specific identification method; (g) 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; (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)
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; ( j) 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 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; (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. At April 30, 2004, reclassifications were made to the
Fund's capital accounts to reflect permanent book/tax differences and income
and gains available for distributions under income tax regulations.
Accordingly, a portion of accumulated net investment loss amounting to
$2,784,687 was reclassified to paid-in capital. Net investment income, net
realized gains and net assets were not affected by this change; and (l)
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.

2. Management Agreement and Other Transactions

Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup"), acts as investment manager to the Fund. The
Fund pays SBFM a management fee calculated at an annual rate of 0.75% of the
Fund's average daily net assets. This fee is calculated daily and paid monthly.

 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


Citicorp Trust Bank, fsb. ("CTB"), another subsidiary of Citigroup, acts as the
Fund's transfer agent. PFPC Inc. ("PFPC") and Primerica Shareholder Services
("PSS"), another subsidiary of Citigroup, act as the Fund's sub-transfer
agents. CTB receives account fees and asset-based fees that vary according to
the size and type of account. PFPC and PSS are responsible for shareholder
recordkeeping and financial processing for all shareholder accounts and are
paid by CTB. For the year ended April 30, 2004, the Fund paid transfer agent
fees of $272,264 to CTB.

Citigroup Global Markets Inc. ("CGM") and PFS Distributors, Inc., both of which

ended April 30, 2004, CGM and its affiliates received brokerage commissions of
$8,960.

On April 29, 2004, the Fund's Class L shares were renamed as Class C shares. On
February 2, 2004, initial sales charges on these shares were eliminated.

There is a maximum initial sales charge of 5.00% for Class A shares. There is a
contingent deferred sales charge ("CDSC") of 5.00% on Class B shares, which
applies if redemption occurs within one year from purchase payment and declines
thereafter by 1.00% per year until no CDSC is incurred. Class C shares also
have a 1.00% CDSC, which applies if redemption occurs within one year from
purchase payment. In certain cases, Class A shares have a 1.00% CDSC, which
applies if redemption occurs within one year from purchase payment. This CDSC
only 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 year ended April 30, 2004, CGM and its affiliates received sales
charges of approximately $549,000 and $63,000 on sales of the Fund's Class A
and C shares, respectively. In addition, for the year ended April 30, 2004,
CDSCs paid to CGM and its affiliates were approximately:

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.

The tax basis components of distributable earnings at April 30, 2004 was:

                   Unrealized depreciation      (17,764,837)
                   -----------------------------------------


At April 30, 2004, the difference between book basis and tax basis unrealized
appreciation and depreciation was attributable primarily to wash sale loss
deferrals.

For the years ended April 30, 2004 and 2003, the Fund did not make any
distributions.

9. 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.

10.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 draw-

 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

ing 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.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM



To the Shareholders and Board of Directors of
Smith Barney Investment Funds Inc.:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the Smith Barney Multiple Discipline Funds --
All Cap Growth and Value Fund ("Fund") (formerly known as Smith Barney Premier
Selections All Cap Growth Fund) of Smith Barney Investment Funds Inc. as of
April 30, 2004, and the related statement of operations for the year then
ended, the statements of changes in net assets for each of the years in the
two-year period then ended and the financial highlights for each of the years
in the three-year period then ended and for the period from June 30, 2000
(commencement of operations) to April 30, 2001. 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. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. Our procedures
included confirmation of securities owned as of April 30, 2004, by
correspondence with the custodian and broker. As to securities purchased but
not received, we performed other appropriate auditing procedures. An audit also
includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. 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 the
Fund as of April 30, 2004, and the results of its operations for the year then
ended, the changes in its net assets for each of the years in the two-year
period then ended and the financial highlights for each of the years in the
three-year period then ended and for the period from June 30, 2000 to April 30,
2001, in conformity with U.S. generally accepted accounting principles.

               Board of each registered investment company (the "Fund") advised
               by Smith Barney Fund Management LLC or Salomon Brothers Asset
               Management Inc or one of their affiliates (each, an "Adviser")
               requires that the Committee shall approve (a) all audit and
               permissible non-audit services to be provided to the Fund and (b)
               all permissible non-audit services to be provided by the Fund's
               independent auditors to the Adviser and any Covered Service
               Providers if the engagement relates directly to the operations
               and financial reporting of the Fund. The Committee may implement
               policies and procedures by which such services are approved other
               than by the full Committee.

               The Committee shall not approve non-audit services that the
               Committee believes may impair the independence of the auditors.
               As of the date of the approval of this Audit Committee Charter,
               permissible non-audit services include any professional services
               (including tax services), that are not prohibited services as

               bookkeeping or other services related to the accounting records
               or financial statements of the Fund; (ii) financial information
               systems design and implementation; (iii) appraisal or valuation
               services, fairness opinions or contribution-in-kind reports; (iv)
               actuarial services; (v) internal audit outsourcing services; (vi)

               investment adviser or investment banking services; (viii) legal
               services and expert services unrelated to the audit; and (ix) any
               other service the Public Company Accounting Oversight Board
               determines, by regulation, is impermissible.

               Pre-approval by the Committee of any permissible non-audit
               services is not required so long as: (i) the aggregate amount of
               all such permissible non-audit services provided to the Fund, the
               Adviser and any service providers controlling, controlled by or
               under common control with the Adviser that provide ongoing
               services to the Fund ("Covered Service Providers") constitutes
               not more than 5% of the total amount of revenues paid to the
               independent auditors during the fiscal year in which the
               permissible non-audit services are provided to (a) the Fund, (b)
               the Adviser and (c) any entity controlling, controlled by or
               under common control with the Adviser that provides ongoing
               services to the Fund during the fiscal year in which the services
               are provided that would have to be approved by the Committee;
               (ii) the permissible non-audit services were not recognized by
               the Fund at the time of the engagement to be non-audit services;
               and (iii) such services are promptly brought to the attention of
               the Committee and approved by the Committee (or its delegate(s))
               prior to the completion of the audit.

          (f)  N/A

          (g)  Non-audit fees billed - $100,000 and $1.2 million for the years
               ended 12/31/2003 and 12/31/2002.

          (h)  Yes. The Smith Barney Investment Funds Inc.'s Audit Committee has
               considered whether the provision of non-audit services that were
               rendered to Service Affiliates which were not pre-approved (not
               requiring pre-approval) is compatible with maintaining the
               Accountant's independence. All services provided by the
               Accountant to the Smith Barney Investment Funds Inc. or to
               Service Affiliates which were required to be pre-approved were
               pre-approved as required.

               effective as of a date within 90 days of the filing date of this
               report that includes the disclosure required by this paragraph,
               based on their evaluation of the disclosure controls and
               procedures required by Rule 30a-3(b) under the 1940 Act and

               financial reporting (as defined in Rule 30a-3(d) under the 1940
               Act) that occurred during the registrant's last fiscal half-year
               (the registrant's second fiscal half-year in the case of an
               annual report) that have materially affected, or are likely to
               materially affect the registrant's internal control over
               financial reporting.
