Tracy Liu: trading record in brief
Tracy Liu is a declared insider of ACM Research, Inc. (senior executive), with filings sourced from SEC (Form 4). We count 6 filings; the first trade dates from 20 November 2023 and the latest from 10 March 2026.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The latest filing, published on 12 March 2026, reports an option exercise of €39k in ACM Research, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.
