Counts cover the 40 most recent Form 4 filings Tradune holds for ZD (filed May 9 – Aug 20, 2026); the score below covers only the trailing 90 days (0 buys, 3 sells). No completed check of ZD's Form 4 list on SEC EDGAR is on record yet; the latest ZD filing Tradune holds was filed Aug 20, 2026. This is not guaranteed to be the complete record — see ZD's full Form 4 filing history on SEC EDGAR.
Open-market activity, last 90 days
Purchases (Form 4 code P) and sales (code S) on the 3 filings Tradune holds for ZD filed Aug 11 – Aug 20, 2026. Grants, exercises, tax withholding and the other Form 4 transaction codes are left out.
filed before Apr 1, 2023, or no checkbox value in the filing data
Counts are Form 4 lines as filed. The checkbox is one per filing, so every sale on a filing with the box checked is counted there even if only some of its transactions were under a plan; it records what the filer disclosed, and the three categories are not a judgement about why a sale was made.

Summarises ~90 days of public SEC Form 4 activity — more distinct buyers, officer involvement and net buying score higher. A description of filing activity, not a rating or buy signal. How this score is computed →
How to read this: an open-market purchase (Form 4 code P) is a buy at the market price with the insider’s own money, as opposed to a grant, award or option exercise; an open-market sale is code S. When two or more distinct insiders report open-market purchases in the same 90-day window, this site labels that a cluster — a definition, not a forecast; see insider cluster buying.
“Held after” is Form 4 Table I column 5; “Change” = shares ÷ holdings before the trade (held after − shares for an acquisition, held after + shares for a disposition).
Insider Buying at ZD
Insiders reported 1 open-market purchase of ZD between May 9, 2025 and Aug 20, 2026, across 1 distinct buyer.
The most recent purchase was reported by Sarah Ann Fay (Director) on Sep 15, 2025.
Grants, option exercises, and tax-withholding transactions are excluded from these counts.
† change in this filer’s own reported holding line (Form 4 Table I, col. 5), not of total company ownership; small prior holdings produce large percentages, so under 100 shares the prior holding is shown instead.
“10b5-1 box checked” = the filer checked the Form 4 box stating that a transaction on the filing was made under a plan intended to satisfy Rule 10b5-1(c); “10b5-1 box not checked” = the box was left blank, which does not prove that no plan exists. The box applies to Form 4s filed from April 1, 2023; older filings, and boxes we could not read, carry no tag. What the 10b5-1 box means.
