Open-market activity, last 90 days

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.

Weekly signal history
ARE appeared in 1 archived weekly edition as a multi-insider cluster, a top net buyer, or both. These are frozen weekly snapshots, not a complete filing history.
An entry means this company met that edition’s displayed cluster or top-buyer threshold. Missing weeks do not mean no insider transaction occurred. All figures are derived from SEC Form 4 filings; open-market buys minus sales are shown as net only when every transaction value was disclosed.
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 ARE
Insiders reported 9 open-market purchases of ARE between May 4, 2026 and Oct 2, 2026, across 2 distinct buyers.
The most recent purchase was reported by Joel S. Marcus (Executive Chairman) on Sep 11, 2026.
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.
Listing the 25 most recent of 29 Form 4 filings held for ARE; the 4 older filings (filed May 4 – May 7, 2026) are counted above but not listed here — see ARE's full Form 4 filing history on SEC EDGAR.
