[Wall Street Urges SEC to Lift Ban on Private Asset Trading] Lobbyists from several major Wall Street alternative asset management firms are requesting regulators to ease restrictions and allow asset transactions between funds managed by the same company. They argue that this move would promote the use of private assets in retirement accounts. The Alternative Investment Management Association, representing firms such as Blackstone Group and Apollo Global Management, is urging the U.S. Securities and Exchange Commission to lift the current ban on so-called private asset cross-trading. This initiative comes as alternative asset management firms prepare to enter 401(k) retirement savings plans and other similar retirement savings programs.
