Gail Boxer Marcus: trading record in brief
Gail Boxer Marcus, listed as senior executive, has filed trades across 2 companies (mainly through SEC (Form 4)), most often in Natera, Inc. and Triple-S Management Corp. Between 16 May 2019 and 26 June 2026, the trades on record add up to 78 filings.
No open-market purchase appears, only 36 sales worth €6.9M. Other entries cover 16 share grants and 25 option exercises.
The record was last updated on 30 June 2026 with a share grant in Natera, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
