Counts cover the 10 most recent Form 4 filings Tradune holds for LGND (filed Jul 6 – Oct 6, 2026); the score below covers only the trailing 90 days (0 buys, 24 sells). No completed check of LGND's Form 4 list on SEC EDGAR is on record yet; the latest LGND filing Tradune holds was filed Oct 6, 2026. This is not guaranteed to be the complete record — see LGND'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 7 filings Tradune holds for LGND filed Aug 4 – Oct 6, 2026. Grants, exercises, tax withholding and the other Form 4 transaction codes are left out.

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 LGND

No open-market insider purchases (Form 4 code P) were reported for LGND between Jul 6, 2026 and Oct 6, 2026. The filings below may include other transaction types — sales, grants, option exercises, and tax withholding — shown for completeness; they are not open-market purchases.

† 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.
