## 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](https://www.sec.gov/newsroom/press-releases/2026-103-sec-seeks-final-judgment-against-former-western-asset-co-cio-ken-leech-cherry-picking-case), 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](https://www.sec.gov/newsroom/press-releases/2026-103-sec-seeks-final-judgment-against-former-western-asset-co-cio-ken-leech-cherry-picking-case), 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.

No license record was present in this snapshot. This data has **not** been checked against current official regulator registers and must **not** be treated as proof of authorization, current license status, or an official warning.

## Enforcement Action Details and Implications

The SEC's press release, catalogued as release number **2026-103** (Source: SEC, 2026), confirms the agency's pursuit of a final judgment in this cherry-picking matter. The consent-based judgment mechanism reflects a negotiated resolution pathway. No additional monetary figures, penalty amounts, disgorgement sums, or specific dates of alleged misconduct are provided in the available source material; figures not present in the source have not been introduced here.
