David M. Mulder: trading record in brief
David M. Mulder (senior executive) discloses dealings in Cyanotech Corp to SEC (Form 4). We count 5 filings; the first trade dates from 18 October 2021 and the latest from 28 August 2025.
The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
The latest filing, published on 2 September 2025, reports 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. Source: insider filings from SEC (Form 4). Past trades are no guide to future returns.
