Regulators clearly prevent stockbrokers' proprietary trading, asset management, and other investment managers from engaging in insider trading.

Reporters have learned that recently the Securities Association has sought opinions from the industry on the "Guidelines for the Management of Investment Behavior of Directors, Supervisors, Senior Management Personnel and Securities Practitioners of Securities Companies", aiming to prevent illegal and irregular investment behavior such as insider trading by practitioners. The new regulations mention that for securities trading, asset management, securities market making, fund custody, fund valuation services and other businesses, securities firms will conduct checks on trading positions in proprietary trading, asset management, securities market making targets, custody or services of fund products, etc., in order to prevent investment managers and other related personnel, as well as their spouses and related parties, from using undisclosed information for securities trading to seek improper gains or provide improper benefits, among other illegal and irregular behaviors.
