_________________________________________________________________
Supplement dated March 28, 2000 to the Prospectus and Application
dated February 29, 2000 of Alliance Select Investor Series,
Technology Portfolio.
This Supplement supersedes certain information under the heading
"Purchase and Sale of Shares -- Initial Offering". Inasmuch as
the initial offering of shares of the Fund raised substantial
assets, the continuous offering of shares originally scheduled to
begin on March 28, 2000 will be delayed to facilitate investment
of the proceeds from the initial offering; except that employees
of Alliance Capital Management L.P., Alliance Fund Distributors,
Inc. or Alliance Fund Services, Inc., and past and present
directors or trustees of other Alliance Mutual Funds, and members
of their immediate family, who were largely unable to purchase
shares in the initial offering, will be permitted to purchase
shares during a limited offering period from March 31, 2000
through April 14, 2000.

You should retain this Supplement with your Prospectus for future
