Michael Manning Collier

Michael Manning Collier, listed as chief executive, appears in our data through filings on Healthstream Inc shares, published by SEC (Form 4). We count 20 filings; the first trade dates from 16 August 2021 and the latest from 29 September 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 record was last updated on 29 September 2026 with an option exercise in Healthstream Inc. The median gap between a trade and its publication by SEC (Form 4) is 1 day. US insiders must file a Form 4 within two business days of a trade. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
