Michael Holder: trading record in brief
Michael Holder (finance chief) discloses dealings in 2 companies, chiefly Cytek Biosciences, Inc. and AVITA Medical, Inc. Over a trading history stretching from 6 July 2021 to 18 August 2026, the count stands at 11 filings.
Not one of the filings records a straightforward purchase or sale on the 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 20 August 2026, reports an option exercise in Cytek Biosciences, Inc. Typically, a trade is published a median of 2 days after it takes place. For comparison, the SEC allows two business days to file a Form 4. This summary is built from SEC (Form 4) disclosures alone and does not predict where the share price will go.
