David L. Vied: trading record in brief
David L. Vied is a declared insider of Cyanotech Corp (board member), with filings sourced from SEC (Form 4). In total, 6 filings cover trades dated from 18 October 2021 to 28 August 2025.
No open-market purchase or sale appears among the filings, only grants, plan transactions and other operations. 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.
On 2 September 2025 came the latest disclosure, a share grant in Cyanotech Corp. Typically, a trade is published a median of 2 days after it takes place. US insiders must file a Form 4 within two business days of a trade. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
