Mark S. Parker: trading record in brief
Mark S. Parker, listed as senior executive, appears in our data through filings on Hydrofarm Holdings Group, Inc. shares, published by SEC (Form 4). We count 52 filings; the first trade dates from 25 February 2022 and the latest from 8 August 2026.
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.
On 11 August 2026 came the latest disclosure, a share grant for €1,027 in Hydrofarm Holdings Group, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
