Steven Lo

Steven Lo is a declared insider at 3 companies (chief executive); the most frequent names are Vaxart, Inc., Puma Biotechnology, Inc. and Zosano Pharma Corp. Over a trading history stretching from 14 October 2016 to 24 March 2026, the count stands at 22 filings.

On the open market, the record shows 1 purchase worth €44k and 9 sales worth €533k. Netting one side against the other leaves €489k of net selling. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. The rest of the record consists of 12 share grants.

Most recently, on 26 March 2026, the filings show a share grant worth €75k in Vaxart, Inc. The clock since the last published purchase (19 May 2025) now reads 523 days. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
