R. Jay Gerken

R. JAY GERKEN, CFA

Chairman, President and Chief Executive Officer

Dear Shareholder,

Upheaval and uncertainty in the global economic and political environment,
including the build-up to war in Iraq, the military campaign and the war's
unsettled aftermath, permeated much of the year ended October 31, 2003. In
addition, foreign markets had to contend with the impact of the SARS epidemic
on economies in the Far East, continued political and economic turmoil in South
America, and Japan's ongoing struggle to get back on solid footing financially
and economically. As the period progressed, international markets responded
positively to low interest rates globally and to signs of economic recovery in
the United States, in Japan, and elsewhere. Consequently, performance results
over the full 12-month period were very positive.

For a more detailed review of how your fund performed within this market
environment, continue reading this report. As always, thank you for entrusting
your assets to us. We look forward to helping you continue to meet your
financial goals.

Sincerely,

/s/ R. Jay Gerken

            1 Smith Barney International Fund | 2003 Annual Report




                               MANAGER OVERVIEW

Performance Review
For the 12 months ended October 31, 2003, Class A shares of the Smith Barney
International Fund (formerly known as Smith Barney International Aggressive
Growth Fund), excluding sales charges, returned 17.13%. These shares
underperformed the fund's unmanaged benchmark, the MSCI EAFE Index,/i/ which
returned 27.03% for the same period. They also underperformed the average of
the fund's Lipper peer group of international funds, which returned 24.51% for
the same period./1/ Past performance is no guarantee of future results.

Market Overview
International markets reached a low point during March, but then recovered
strongly over the balance of the year, due to a combination of low global
interest rates, perceived reduction in geopolitical risk following early
coalition military success in Iraq, and signs of economic recovery in the
United States, Japan and elsewhere. Over the 12-month period, the greatest
increases were seen in Australia and the Pacific. From a sector perspective,
the recovery has been greatest in cyclical areas such as information technology
and materials. By contrast, more stable growth sectors, such as consumer
staples and healthcare, have lagged significantly.

Markets this year have been focused on recovery prospects for corporate
profits. Companies that operate in more depressed businesses or which suffer
from weak financial positions have tended to outperform, as the market
anticipates that these companies will enjoy the greatest relief from economic
recovery. Soundly financed companies, operating in attractive, high-return
businesses, but with less leverage to improving economic conditions, have
tended to underperform, despite enjoying generally lower valuations than their
more cyclical counterparts.


                             PERFORMANCE SNAPSHOT
                            AS OF OCTOBER 31, 2003
                           (excluding sales charges)



                                         6 Months 12 Months

Average of Lipper international funds     23.18%    24.51%


   Class A share returns assume the reinvestment of income dividends and
   capital gains distributions at net asset value and the deduction of all fund
   expenses. Returns have not been adjusted to include sales charges that may
   apply when shares are purchased or the deduction of taxes that a shareholder
   would pay on fund distributions.

   The MSCI EAFE Index is an unmanaged index of common stocks of companies
   located in Europe, Australasia and the Far East. Please note that an
   investor cannot invest directly in an index.

   Lipper Inc. is a major independent mutual-fund tracking organization.
   Returns are based on the period ended October 31, 2003, calculated among 868
   funds for the six-month period and among 835 funds for the 12-month period,
   in the fund's Lipper peer group including the reinvestment of dividends and
   capital gains and excluding sales charges.

   All figures represent past performance and are not a guarantee of future
   results. Principal value and investment returns will fluctuate and
   investors' shares, when redeemed may be worth more or less than their
   original cost. Performance of other share classes may vary.

Fund Performance
The fund focuses on companies that our analysis suggests are most attractive
within their global sectors in terms of long-term valuations and seek to
project cash flows and dividends several years into the future. While this
approach remains a proven long-term strategy, it has proved less effective in
an environment focused primarily on short-term recovery prospects. We emphasize
stock selection rather than geographic or sector allocations when constructing
the fund's portfolio.

   Returns are based on the 12-month period ended October 31, 2003, calculated

            2 Smith Barney International Fund | 2003 Annual Report





The strategy resulted in disappointing stock selection in Japan and continental
Europe. In Japan, the fund did not hold domestic financial companies such as
UFJ Holdings and Mizuho Financial, but did hold overweight positions in
exporting companies such as Honda Motor Co., Ltd., Toyota Motor Corp. and Canon
Inc. A combination of domestic cyclical recovery and the rise in the Japanese
yen against the U.S. dollar made this positioning disadvantageous in the short
term. As of the end of the period, the fund remained underweight in the
Japanese financials sector and continued to hold Honda, Toyota and Canon.
Within continental Europe, selection suffered in France and Switzerland, with
Sanofi-Synthelabo and Nestle S.A., held with overweight positions for much of
the period, the largest detractors respectively. We sold both Sanofi-Synthelabo
and Nestle during the period.

Partially offsetting these factors, the fund benefited from positive stock
selection in the United Kingdom, where Hanson PLC, Tesco PLC and Wolseley PLC
contributed positively. As of the end of October, Tesco remained in the fund
but we have sold Hanson and Wolseley.

Additional Information About Your Fund

information from various government regulators regarding market timing, late
trading, fees and other mutual fund issues in connection with various
investigations. 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.

Thank you for your investment in the Smith Barney International Fund. We

relationship with you.

            11 Smith Barney International Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS


1. Significant Accounting Policies
The Smith Barney International Fund ("Fund") (formerly known as the Smith
Barney International Aggressive Growth Fund), is a separate investment fund of
the Smith Barney Investment Series ("Trust"), a Massachusetts business trust,
is registered under the Investment Company Act of 1940, as amended, ("1940
Act") as a diversified open-end management investment company. The Trust
consists of this Fund and six other separate investment funds: Smith Barney
Large Cap Core Fund, SB Growth and Income Fund (formerly known as Smith Barney
Growth and Income Fund), Smith Barney Large Cap Core Portfolio, Smith Barney
Premier Selections All Cap Growth Portfolio, Smith Barney Growth and Income
Portfolio and SB Government Portfolio (formerly known as Smith Barney
Government Portfolio). The financial statements and financial highlights for
the other funds are presented in separate shareholder reports.

The significant accounting policies consistently followed by the Fund are: (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, if there were no sales during the day, at fair value determined by or under
the direction of the Board of Trustees; 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; securities primarily traded on foreign exchanges
are generally valued at the preceding closing values of such securities on
their respective exchanges, except that when a significant event, subsequent to
the time a value was so established, is likely to have significantly changed
the value, then the fair value of those securities will be determined by
consideration of other factors by or under the direction of the Board of
Trustees or its delegates; over-the-counter securities are valued on the basis
of the bid price at the close of business on each day; U.S. government and
agency obligations are valued at the average between bid and asked prices in
the over-the-counter market; (c) securities maturing within 60 days are valued
at cost plus accreted discount, or minus amortized premium, which approximates
value; (d) 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
Trustees; (e) interest income, adjusted for amortization of premium and
accretion of discount, is recorded on the accrual basis; (f ) dividend income
is recorded on the ex-dividend date; 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;
(g) gains or losses on the sale of securities are calculated by using the
specific identification method; (h) 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; (i) dividends
and distributions to shareholders are recorded by the Fund on the ex-dividend
date; the Fund distributes dividends and capital gains, if any, at least
annually; ( 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 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 and expense amounts recorded and collected or paid are adjusted
when reported by the custodian bank; (k) realized gain and loss on foreign
currency includes the net realized amount from the sale of currency and the
amount realized between trade date and settlement date on security
transactions; ( l) the character of income and gains to be distributed is
determined in accordance with income tax regulations which may differ from
accounting principles generally accepted in the United States of America. At
October 31, 2003, 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, accumulated net
investment loss amounting to $1,092,987 and expired capital loss carryforwards
from accumulated net realized loss amounting to $245,990 were reclassified to
paid-in capital. Net investment income, net realized gains and net assets were
not affected by this change; (m) the Fund intends to comply with the
requirements 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 (n) 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

            12 Smith Barney International Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS (CONTINUED)

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 foreign 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.

2. Management Agreement and Other Transactions
Smith Barney Fund Management LLC ("SBFM"), an indirect wholly-owned subsidiary
of Citigroup Inc. ("Citigroup"), acts as the investment manager to the Fund.
The Fund pays SBFM a management fee calculated at an annual rate of 1.00% of
the Fund's average daily net assets. The fee is calculated daily and paid
monthly.

Effective January 21, 2003, SBFM entered into a sub-advisory agreement with
Citigroup Asset Management Ltd. ("CAM Ltd."). Pursuant to the sub-advisory
agreement, the sub-adviser is responsible for the day-to-day fund operations
and investment decisions of the Fund. SBFM pays CAM Ltd. a sub-advisory fee
calculated at an annual rate of 0.70% of the aggregate assets of the Fund
allocated to the sub-adviser.

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. For the year ended October 31, 2003, the Fund
paid transfer agent fees of $1,110,327 to CTB.

Citigroup Global Markets Inc. ("CGM") (formerly known as Salomon Smith Barney
Inc.) and PFS Distributors, Inc., both of which are subsidiaries of Citigroup,
act as the Fund's distributors. For the year ended October 31, 2003, CGM and
its affiliates received brokerage commissions of $813.

There are maximum initial sales charges of 8.50%, 5.00% and 1.00% for Class 1,
A and L shares, respectively. 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 by 1.00% per year until no CDSC is
incurred. Class L 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 October 31, 2003, CGM and its affiliates received sales
charges of approximately $9,000 and $269,000 on the sale of the Fund's Class 1
and A shares, respectively. In addition, for the year ended October 31, 2003,
CDSCs paid to CGM and its affiliates were approximately $122,000 for Class B
shares.

All officers and one Trustee of the Trust are employees of Citigroup or its
affiliates.

The Trustees of the Funds have adopted a Retirement Plan ("Plan") for all
Trustees who are not "interested persons" of the Fund, within the meaning of
the 1940 Act. Under the Plan, all Trustees are required to retire from the
Board as of the last day of the calendar year in which the applicable Trustee
attains age 75 (certain Trustees who had already attained age 75 when the Plan
was adopted are required to retire effective December 31, 2003). Trustees may
retire under the Plan before attaining the mandatory retirement age. Trustees
who have served as Trustee of the Trust or any of the investment companies
associated with Citigroup for at least ten years when they retire are eligible
to receive the maximum retirement benefit under the Plan. The maximum
retirement benefit is an amount equal to five times the amount of retainer and
regular meeting fees payable to a Trustee during the calendar year ending on or
immediately prior to the applicable Trustee's retirement. Amounts under the
Plan may be paid in installments or in a lump sum (discounted to present
value). Benefits under the Plan are unfunded. Two former Trustees are currently
receiving payments under the Plan. Two additional Trustees have announced their
intention to retire, effective December 31, 2003. The amount of benefits to be
paid under the Plan cannot currently be determined for current Trustees.

            13 Smith Barney International Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


Messrs. Carlton, Cocanougher, Gross, Merten and Pettit also are covered by a
prior retirement plan. Under the prior plan, retirement benefits are payable
for a ten-year period following retirement, with the annual payment to be based
upon the Trustee's compensation from the Trust during calendar year 2000.
Trustees with more than five but less than ten years of service at retirement
will receive a prorated benefit. In order to receive benefits under the current
Plan, a Trustee must waive all rights under the prior plan prior to receiving
payment under either plan. Total aggregate retirement benefits accrued under
the prior plan for the year ended October 31, 2003 were $3,865. The amount of
benefits to be paid under the prior plan cannot currently be determined for
these.

3. Investments
During the year ended October 31, 2003, 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                                     $139,861,196
- ---------------------------------------------------------
Sales                                          134,054,009
- ---------------------------------------------------------

At October 31, 2003, the aggregate gross unrealized appreciation and
depreciation of investments for Federal income tax purposes were as follows:

- --------------------------------------------------------
Gross unrealized appreciation               $11,947,453
Gross unrealized depreciation                (2,041,665)
- --------------------------------------------------------
Net unrealized appreciation                 $ 9,905,788
- --------------------------------------------------------

4. Repurchase Agreements
The Fund purchases (and the custodian takes possession of ) U.S. government
securities from securities dealers subject to agreements to resell the
securities to the sellers at a future date (generally, the next business day),
at an agreed-upon higher repurchase price. The Fund requires continual
maintenance of the market value (plus accrued interest) of the collateral in
amounts at least equal to the repurchase price.

5. Foreign Securities
Investing in securities of foreign companies and foreign governments involves
special risks and considerations not typically associated with investing in
U.S. companies and the U.S. government. These risks include revaluation of
currencies and future adverse political and economic developments. Moreover,
securities of many foreign companies and foreign governments and their markets
may be less liquid and their prices more volatile than those of securities of
comparable U.S. companies and the U.S. government.

6. Lending of Portfolio Securities

The Fund has an agreement with its custodian whereby the custodian may lend
securities owned by the Fund to brokers, dealers and other financial
organizations. Fees earned by the Fund on securities lending are recorded in
interest income. Loans of securities by the Fund are collateralized by cash,
U.S. government securities or high quality money market instruments that are
maintained at all times in an amount at least equal to the current market value
of the loaned securities, plus a margin which may vary depending on the type of
securities loaned. The Fund maintains exposure for the risk of any loss in the
investment of amounts received as collateral.

            14 Smith Barney International Fund | 2003 Annual Report




 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


At October 31, 2003, the Fund loaned securities having a market value of
$11,413,545. The Fund received cash collateral amounting to $11,788,380 which
was invested in the State Street Navigator Securities Lending Trust Prime
Portfolio.

Income earned by the Fund from securities lending for the year ended October
31, 2003 was $70,156.

with respect to its Class A, B and L shares calculated at an annual rate not to

 NOTES TO FINANCIAL STATEMENTS (CONTINUED)


9. Capital Loss Carryforward

At October 31, 2003, the Fund had, for Federal income tax purposes,
approximately $111,563,000 of unused capital loss carryforwards available to
offset future capital gains. To the extent that these carryforward losses are
used to offset capital gains, it is probable that the gains so offset will not
be distributed.

The amount and year of expiration for each carryforward loss is indicated
below. Expiration occurs on October 31 of the year indicated:



                                      2004      2005      2006      2008       2009        2010        2011
- ---------------------------------------------------------------------------------------------------------------
                                                                               
Carryforward Amounts                $515,000 $3,257,000 $570,000 $4,017,000 $29,633,000 $43,173,000 $30,398,000
- --------------------------------------------------------------------------------------------------------------


10.Income Tax Information and Distributions to Shareholders

At October 31, 2003, the tax basis components of distributable earnings were:


                                 
- -------------------------------------------------
Accumulated capital losses          $(111,562,977)
- -------------------------------------------------
Unrealized appreciation                 9,914,780
- -------------------------------------------------


The difference between book basis and tax basis unrealized appreciation and
depreciation is attributable primarily to wash sale loss deferrals.

For the year ended October 31, 2003, the Fund did not make any distributions.

11.Subsequent Event

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
$16 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.

 INDEPENDENT AUDITORS' REPORT


To the Shareholders and Board of Trustees
of Smith Barney Investment Series:


We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the Smith Barney International Fund (formerly
known as Smith Barney International Aggressive Growth Fund), of Smith Barney
Investment Series ("Fund") as of October 31, 2003, 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 four-year period then ended. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits. The
financial highlights for the year ended October 31, 1999 were audited by other
auditors whose report thereon, dated December 15, 1999, expressed an
unqualified opinion on the financial highlights.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. 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 October 31, 2003 by
correspondence with the custodian. As to securities purchased or sold but not
yet received or delivered, 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 October 31, 2003, 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 financial highlights for each of the years in the
four-year period then ended in conformity with accounting principles generally
accepted in the United States of America.
