ACM Research’s shares declined by 1.87% in the most recent trading session, underperforming the broader market’s flat performance. This pullback follows a 132% rally since January, when Kerrisdale Capital branded the stock a “10-Bagger.” Trading volume surged 45% above its 30-day average, suggesting profit-taking by short-term holders who captured gains after the stock’s rapid ascent earlier this year.

The company’s wholly consolidated Chinese arm, ACM Research (Shanghai) Inc., is valued at approximately $12.2 billion. With ACM Research owning 74.6% of that unit, the implied equity stake is worth roughly $9.1 billion—more than three times the U.S. listing’s $2.64 billion market capitalization. This discrepancy underscores a significant arbitrage opportunity, as investors in the Nasdaq-traded entity effectively gain exposure to a Chinese operation whose equity value is being largely unlocked but not fully reflected in the share price.

Analysts forecast 16% revenue growth for fiscal 2025 and 18.3% for fiscal 2026, driven by robust demand for wet cleaning and electroplating tools in advanced logic and foundry fabs. With the stock trading below 20 times forward earnings, ACM Research looks inexpensive relative to peers that command multiples above 25 on similar growth trajectories. Management’s strategy of leveraging the Shanghai arm’s market dominance while maintaining a U.S. parent listed in a less volatile jurisdiction provides investors with a diversified risk profile and upside potential as semiconductor capital expenditure recovers globally.
