SEC Moves for Final Judgment Against Western Asset's Former Co-CIO#
The U.S. Securities and Exchange Commission (SEC) has formally moved for entry of a final judgment by consent against Stephen Kenneth Leech II (Source: SEC Press Release 2026-103, 2026). Leech served as the former co-chief investment officer of Western Asset Management Company LLC, a registered investment adviser. The SEC's action centers on alleged cherry-picking — a practice in which favorable trades are selectively allocated to preferred accounts at the expense of other clients.
Cherry-picking is defined as the fraudulent practice whereby a portfolio manager or trader allocates winning trades to favored accounts after observing intraday price movements, while assigning losing or underperforming trades to disfavored accounts. This conduct violates fiduciary duties owed to all clients under federal securities law.
Key Parties and Regulatory Context#
Western Asset Management Company LLC is identified in the SEC's action as a registered investment adviser (Source: SEC Press Release 2026-103, 2026). Stephen Kenneth Leech II held the title of co-chief investment officer at the firm at the time of the alleged conduct. The SEC's motion for a final judgment by consent indicates that the resolution is proceeding on an agreed basis between the regulator and the defendant, a procedural mechanism commonly used to conclude enforcement actions without a contested trial.
