David H. Li

David H. Li is a declared insider at 3 companies (chief executive); the most frequent names are CMC Materials, Inc., Ingevity Corp and Hexcel Corp /DE/. Between 31 December 2015 and 3 October 2026, the trades on record add up to 25 filings.

Every open-market trade on record is a sale: 5 sales worth €1.3M. The rest of the record consists of 12 share grants and 6 option exercises. In 2026 alone, the filings show no purchases and 5 sales.

Most recently, on 5 October 2026, the filings show an option exercise in Hexcel Corp /DE/. Filings reach the SEC (Form 4) feed a median of 2 days after the trade. For comparison, the SEC allows two business days to file a Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
