     PART A

PROSPECTUS

The prospectus dated July 14, 1997 for Smith Barney Large Capitalization 
Growth Fund filed with Post-Effective Amendment No. 13 to the Fund's 
Registration Statement on Form N-1A, is incorporated herein by reference.
    

THE FUND'S EXPENSES.  The following expense table lists the costs and expenses 
an investor
will incur either directly or indirectly as a shareholder of the Fund, based 
on the maximum sales
charge or maximum CDSC that may be incurred at the time of purchase or 
redemption and
the Fund's operating expenses for the fiscal year ended November 30, 1997.

<TABLE>
<CAPTION>
<S>	Class A	Class B	Class C	Class Y
							<C>	    <C>	       <C>  
	<C>
Shareholder Transaction Expenses
Maximum sales charge imposed on
purchases (as a percentage of offering price)	5.00%	None	None	None
Maximum Redemption Fee or CDSC (as a
percentage of original cost or redemption 
proceeds, whichever is lower)	None*	5.00%	1.00%	None

Annual Fund Operating Expenses
(as a percentage of average net assets)
Management fees	0.75%	0.75%	0.75%	0.75%
12b-1 Fees**	0.25	1.00	1.00	None
Other Expenses***	0.15	0.15	0.15	0.07

Total Fund Operating Expenses	1.15%	1.90%	1.90%	0.82%

</TABLE>

*Purchases of Class A shares of $500,000 or more will be made at net asset 
value with no
sales charge, but will be subject to a CDSC of 1.00% on redemptions made 
within 12 months
of purchase.
**Upon conversion of Class B shares to Class A shares, such shares will no 
longer be
subject to a distribution fee. Class C shares do not have a conversion feature 
and, therefore,
are subject to an ongoing distribution fee.  As a result, long-term 
shareholders of Class C 
shares may pay more than the economic equivalent of the maximum front-end 
sales charge
permitted by the National Association of Securities Dealers, Inc.
***"Other Expenses" have been estimated based on expenses the Fund expects to 
incur during its fiscal year ended November 30, 1997.

Example
	The following example is intended to assist an investor in understanding 
the various costs that an investor in the Fund will bear directly or 
indirectly.  The example assumes payment by the Fund of operating expenses at 
the levels set forth in the table above.  See "Purchase of Shares," " 
Redemption of Shares" and "Management of the Trust and Fund."


		1 Year	3 Years	
An investor would pay the following expenses on
a $1,000 investment, assuming (1) 5.00% annual
return and (2) redemption at the end of each
period:
	Class A	.......		$61		$85	
	Class B	.......		  69		  90	
	Class C	.......		  29		  60	
	Class Y 	............................................................
