Steven S. Williamson: trading record in brief
Filings by Steven S. Williamson span 2 companies, the busiest being Outset Medical, Inc. and Pulmonx Corp. Between 16 November 2021 and 2 September 2025, the trades on record add up to 19 filings.
Market trades split into 1 purchase (€88k) and 13 sales (€742k). Sales outweigh purchases by €654k. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 5 share grants. In 2025 alone, the filings show no purchases and 3 sales.
The record was last updated on 3 September 2025 with an open-market sale (€7,037) in Pulmonx Corp. The clock since the last published purchase (22 August 2024) now reads 787 days. 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
