Gregory C. Critchfield: trading record in brief
Gregory C. Critchfield, listed as chief executive, appears in our data through filings on Sera Prognostics, Inc. shares, published by SEC (Form 4). We count 7 filings; the first trade dates from 19 July 2021 and the latest from 10 July 2026.
Not one of the filings records a straightforward purchase or sale on the market. Grants and option exercises follow pay plans set in advance, so they reveal less about an insider's own view than a purchase made with personal money.
The newest entry dates from 14 July 2026: a share grant, in Sera Prognostics, Inc. 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
