Item 1. Business

General

   Prudential Securities Aggressive Growth Fund L.P. (the 'Registrant'), a
Delaware limited partnership, was formed on February 17, 1993 and will terminate
on December 31, 2013 unless terminated sooner under the provisions of the
Amended and Restated Agreement of Limited Partnership (the 'Partnership
Agreement'). The Registrant was formed to engage in the speculative trading of a
portfolio consisting primarily of commodity futures, forward and options
contracts. On August 2, 1993, the Registrant completed its initial offering with
sales of 102,383 units of limited partnership interest and 1,500 units of
general partnership interest (collectively, 'Units') which resulted in net
proceeds to the Registrant of $10,180,534. The Registrant continued to offer
Units on a monthly basis until the continuous offering was terminated on January
31, 1995. Additional contributions raised through the continuous offering
resulted in additional net proceeds to the Registrant of $9,988,243. The
Registrant's fiscal year for book and tax purposes ends on December 31.

   Since October 1, 1997, trading decisions for the Registrant are made by Eagle
Trading Systems, Inc. ('Eagle') and Welton Investment Systems Corporation,
independent commodity trading managers. Eagle replaced Sjo, Inc. ('Sjo') as a
trading manager effective October 1, 1997. Eagle receives management fees at the
same rate ad did Sjo (a monthly fee on traded assets equal to a 2% annual rate).
In addition, Eagle earns a quarterly incentive fee equal to 23% of New High Net
Trading Profits (as defined in the Advisory Agreement among the Registrant, the
General Partner and Eagle) as compared to a monthly incentive fee of 15% paid to
Sjo. Except for the October 1, 1997 replacement of Sjo, there were no changes in
trading managers during the three years ended December 31, 1997. The General
Partner retains the authority to override trading instructions that violate the
Registrant's trading policies.

   The Registrant is engaged solely in the business of commodity futures,
forward and options trading; therefore, presentation of industry segment
information is not applicable.

General Partner

   The general partner of the Registrant is Prudential Securities Futures
Management Inc. (the 'General Partner'). The General Partner is a wholly owned
subsidiary of Prudential Securities Incorporated ('PSI'), which in turn is a
wholly owned subsidiary of Prudential Securities Group Inc. ('PSGI'). PSI was
the principal underwriter of the limited partnership units and is the commodity
broker of the Registrant. The General Partner is required to maintain at least a
1% interest in the Registrant as long as it is acting as the Registrant's
general partner.

Competition

   The General Partner and its affiliates have formed and may continue to form
various entities to engage in the speculative trading of futures, forward and
options contracts which, in part, have certain of the same investment policies
as the Registrant.

   The Registrant is a closed-ended fund which solicited the sale of additional
Units on a monthly basis until the continuous offering was terminated and does
not intend to solicit the sale of additional Units in the future. As such, the
Registrant does not compete with other entities to attract new fund
participants. However, to the extent that the trading managers recommend similar
or identical trades to the Registrant and other accounts which they manage, the
Registrant may compete with those accounts for the execution of the same or
similar trades.

Employees

   The Registrant has no employees. Management and administrative services for
the Registrant are performed by the General Partner and its affiliates pursuant
to the Partnership Agreement. See Notes A, C and D to the Registrant's annual
report to limited partners for the year ended December 31, 1997 ('Registrant's
1997 Annual Report') which is filed as an exhibit hereto.

Item 2. Properties

   The Registrant does not own or lease any property.

                                       3
<PAGE>
Item 3. Legal Proceedings

   There are no material legal proceedings pending by or against the Registrant
or the General Partner.

Item 4. Submission of Matters to a Vote of Limited Partners

   None

                                    PART II

Item 5. Market for the Registrant's Units and Related Limited Partner Matters

   As of March 5, 1998, there were 544 holders of record owning 66,363.974 Units
which include 664 units of general partnership interest. A significant secondary
market for the Units has not developed, and it is not expected that one will
develop in the future. There are also certain restrictions set forth in the
Partnership Agreement limiting the ability of a partner to transfer Units. The
Partnership Agreement provides that a limited partner may redeem its units as of
the last business day of any full calendar quarter at the then current net asset
value per Unit reduced by each Unit's pro rata portion of unamortized
organizational costs. Consequently, holders of Units may not be able to
liquidate their investment in the event of an emergency or for any other reason.

   There are no material restrictions upon the Registrant's present or future
ability to make distributions in accordance with the provisions of the
Partnership Agreement. No distributions have been made since inception and no
distributions are anticipated in the future.

Item 6. Selected Financial Data

   The following table presents selected financial data of the Registrant. This
data should be read in conjunction with the financial statements of the
Registrant and the notes thereto on pages 2 through 10 of the Registrant's 1997
Annual Report which is filed as an exhibit hereto. The data presented for the
period ended December 31, 1993 does not represent a full year's operations.
