R. Jay Gerken

R. JAY GERKEN, CFA

Chairman, President and Chief Executive Officer

Dear Shareholder,
For the six months ended April 30, 2004, the key factors driving the stock
market were the strength of the global economy and fears that steps would be
taken by the U.S. and Chinese governments to slow the growth of their
economies. The closing months of 2003 saw a powerful cyclical stock market
rally. However, since the beginning of 2004, many investors saw a far bumpier
market, as signs of increasing inflation appeared in the U.S.

U.S. economic data during April showed a strong economy, with the greatest
strength in the industrial segments. While oil prices hit new highs, other
commodity prices fell sharply due, in our opinion, to comments from the Chinese
government indicating it was taking steps to slow the very rapid growth of the
economy. A significant portion of the companies included in the S&P 500 Index
beat their consensus earnings expectations.

Performance Review
Within this environment, the fund performed as follows: For the six months
ended April 30, 2004, Smith Barney Class A shares of the SB Growth and Income
Fund, excluding sales charges, returned 4.63%. In comparison, the fund's
unmanaged benchmark, the S&P 500 Index,/i/ returned 6.27%. The fund
outperformed it's Lipper large-cap core funds category average, which returned
4.52%./1/


                             PERFORMANCE SNAPSHOT
                             AS OF APRIL 30, 2004
                           (excluding sales charges)



                                             6 Months

   charges.

             1 SB Growth and Income Fund | 2004 Semi-Annual Report





Explanation of Performance
The fund's underperformance relative to the S&P 500 Index can be attributed to
poor stock selection in the information technology and consumer discretionary
sectors. Performance was hampered by holdings in global telecommunications
equipment maker Nortel Networks Corp., semiconductor manufacturer Infineon
Technologies AG, and consumer electronics retailer Best Buy Co. Inc. However,
the fund's performance was helped by select positions in the telecommunication
services, health care and industrial sectors. In particular, performance
benefited from holdings in mobile service provider AT&T Wireless Services Inc.,
biotechnology company Elan Corp. PLC and manufacturing conglomerate Tyco
International Ltd.

Special Shareholder Notice
Effective April 29, 2004, Smith Barney Class L shares were renamed Smith Barney
Class C shares. On April 29, 2004 Salomon Brothers Class 2 shares were renamed
Salomon Brothers Class C shares. On February 2, 2004, initial sales charges on
Smith Barney Class C shares and Salomon Brothers Class C shares were
eliminated. On April 29, 2004, initial sales charges on Smith Barney Class O
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

            10 SB Growth and Income Fund | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

1. Significant Accounting Policies

The SB Growth and Income Fund ("Fund") is a separate investment fund of the
Smith Barney Investment Series ("Trust"). The 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 International Fund, Smith Barney Large Cap Core 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. 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, if there were no sales during the day, at fair value
determined by or under the direction of the Board of Trustees; 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 at the mean between the bid and asked prices; U.S.
government and agency obligations are valued at the average between bid and
asked prices in the 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 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 an 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 quarterly 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 U.S. generally accepted accounting
principles; (m) 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 (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 economic environment, financial markets and any
other parameters used in determining these estimates could cause actual results
to differ.

            11 SB Growth and Income Fund | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)


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.

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, which is calculated daily and paid monthly, at
an annual rate of the Fund's average daily net assets as follows:

- -------------------------------------------------------------------------------
First $1 billion                                                       0.65%

- ------------------------------------------------------------------------------

During the six months ended April 30, 2004, SBFM voluntarily reimbursed
expenses amounting to $9,300 related to certain class specific expenses for
Salomon Brothers Class A, Salomon Brothers Class B and Salomon Brothers Class C
shares. This voluntary reimbursement can be terminated at any time by SBFM.

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 six months ended April 30, 2004, the Fund paid transfer
agent fees of $1,250,739 to CTB.

Citigroup Global Markets Inc. ("CGM") and PFS Distributors, Inc. ("PFS"), both
of which are subsidiaries of Citigroup, act as the Fund's distributors.

On April 29, 2004, Smith Barney Class L and Salomon Brothers Class 2 shares
were renamed as Smith Barney Class C and Salomon Brothers Class C shares,
respectively. On February 2, 2004, initial sales charges on Smith Barney Class
C and Salomon Brothers Class C shares were eliminated. On April 29, 2004,
initial sales charges on Smith Barney Class O shares were eliminated.

There are maximum initial sales charges of 8.50%, 5.00% and 5.75% for Smith
Barney Class 1, Smith Barney Class A and Salomon Brothers Class A shares,
respectively. There is a contingent deferred sales charge ("CDSC") of 5.00% on
Smith Barney Class B, Smith Barney Class P and Salomon Brothers 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. Smith Barney
Class C, Smith Barney Class O and Salomon Brothers Class C shares also have a
1.00% CDSC, which applies if redemption occurs within one year from purchase
payment. In certain cases, Smith Barney Class A and Salomon Brothers 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 Smith
Barney Class A and Salomon Brothers Class A shares which, when combined with
current holdings of Smith Barney Class A and Salomon Brothers Class A shares,
respectively, 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 $482,000, $542,000, $5,000 and $26 on sales on the

                                         Smith Barney Smith Barney
                                           Class B      Class P
- ------------------------------------------------------------------
CDSCs                                      $126,000      $7,000
- -----------------------------------------------------------------

For the six months ended April 30, 2004, CGM and its affiliates did not receive
any brokerage commissions for the Fund's portfolio agency transactions.

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. In addition, two other Trustees elected to
receive a lump sum payment from this plan during the period. The amount of
benefits to be paid under the Plan cannot currently be determined for current
Trustees.

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 six months ended April 30, 2004 were $16,125. The amount of
benefits to be paid under the prior plan cannot currently be determined for
these Trustees.

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                                 $287,959,260

- ------------------------------------------------------
Net unrealized appreciation              $167,371,478
- ------------------------------------------------------

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. 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 losses in
the investment of amounts received as collateral.

At April 30, 2004, the Fund loaned securities having a market value of
$82,031,690. The Fund received cash collateral amounting to $86,019,691 which
was invested in the State Street Navigator Securities Lending Trust Prime
Portfolio.

Income earned by the Fund from securities lending for the six months ended
April 30, 2004 was $49,302.

7. Class Specific Expenses

Pursuant to Rule 12b-1 Service Plans, the Fund pays a distribution/service fee
with respect to its Smith Barney Class A, Smith Barney Class B, Smith Barney
Class C, Smith Barney Class O, Smith Barney Class P, Salomon Brothers Class A,
Salomon Brothers Class B and Salomon Brothers Class C shares calculated at an
annual rate not to exceed 0.25%, 1.00%, 1.00%, 0.70%, 0.75%, 0.25%, 1.00% and
1.00% of the average daily net assets of each class, respectively. For the six
months ended April 30, 2004, total Rule 12b-1 Service Plan fees, which are
accrued daily and paid monthly, were as follows:

10.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

            16 SB Growth and Income Fund | 2004 Semi-Annual Report




 NOTES TO FINANCIAL STATEMENTS (UNAUDITED) (CONTINUED)

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.

11.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.
