Sciammas Maurice, EVP of Worldwide Sales & Marketing, has demonstrated a consistent pattern of selling shares in Monolithic Power Systems, Inc. (MPWR), as evidenced by SEC Form 4 filings. Over the course of 38 reported transactions, Maurice has exclusively sold shares, with no recorded purchases. The total value of these sales amounts to $121,406,949.23, reflecting a significant divestment in the company. Notably, 24 of these transactions occurred recently, spanning from November 2025 to March 2026, indicating an ongoing trend of reducing his holdings.
The most substantial single sale took place on February 6, 2026, when Maurice sold shares valued at $26,790,369.64. This was followed by a series of smaller transactions on November 19, 2025, where multiple sales ranged from $191,719 to $5,754,235.50. These transactions collectively underscore a deliberate effort to liquidate a substantial portion of his equity in MPWR. The absence of any buying activity during this period further highlights Maurice’s focus on divestment rather than accumulation.
Maurice’s trading activity is concentrated solely in MPWR, with no diversification into other companies. The consistent selling pattern, particularly the high-volume transactions in late 2025 and early 2026, suggests a strategic reduction in his stake in the company. While the filings provide no insight into the rationale behind these sales, the data clearly illustrates a one-sided trading bias toward selling, marking a significant shift in his investment position within Monolithic Power Systems.
