AmirAli Talasaz

AmirAli Talasaz is a declared insider of Guardant Health, Inc. (chief executive), with filings sourced from SEC (Form 4). Over a trading history stretching from 13 August 2021 to 1 October 2026, the count stands at 40 filings.

On the open market, the record shows 2 purchases worth €3.5M and 11 sales worth €6.3M. The totals do not cover 6 filings with an undisclosed amount. 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 4 share grants and 19 option exercises. Since January 2026: no purchases and 9 sales on the market.

Most recently, on 2 October 2026, the filings show an option exercise in Guardant Health, Inc. The last purchase on record was published on 15 March 2023, which is 1,313 days ago. The median gap between a trade and its publication by SEC (Form 4) is 2 days. 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.
