Chen Fuping sells 120,000 shares (100% of holdings) at $33.18 average, raising $3,981,156.00
Chen Fuping executed 3 separate sales on 2025-12-02 and 2025-12-03, liquidating his entire 120,000-share position in ACM Research for a blended average price of $33.18. This represents complete divestiture: the post-transaction holding is 0 shares, down from 120.0K shares pre-transaction. At the SAME-TICKER HISTORY level, his one prior sell at ACMR (2023-08-23) returned +16.7% over 90 days, indicating the stock rose after that prior exit—a poorly-timed outcome relative to what followed. The stock currently trades at $34.62, 3.9% above the blended sale price, though it has fallen 11.0% over 30 days and sits 20.9% below its 52-week high of $43.78. ACM Research shows strong fundamentals: $269.2M in latest quarterly revenue, net income of $35.9M, and 40.2% annual revenue growth, with a P/E of 4.19 and market cap of $490.8M. The complete elimination of the insider's stake merits scrutiny given the company's growth profile and profitable operations, particularly in light of recent price weakness following a 26.3% 90-day gain.
