"Disclosed insider exposure" sums this person's most-recently-reported share counts across each company they're an insider in, multiplied by the current underlying price. It is not net worth — it misses retail holdings, private investments, real estate, index funds, and any company where the person isn't an SEC-reporting insider. For informational purposes only.

Insider activity across all companies, newest first. Form 4 rows are post-trade confirmations (buys, sells, grants, exercises). Notice (144) rows are pre-trade notices of intent to sell restricted or control stock under Rule 144, so not all of them end in a sale. Under each notice: the role the filer ticked on it, and whether a sale followed (a Form 4 sale within 30 days, or a sale listed on a later notice).

Form 4 codes: P = open-market purchase · S = open-market sale · A = grant/award · M = option exercise · F = tax withholding at vest · G = bona-fide gift · D = disposition to issuer · J = other (see filing footnote). Only P / S codes carry directional signal.
Notice (144 / 144/A): Form 144 is a notice of intent to sell restricted/control stock under Rule 144, filed before the sale; 144/A is an amendment, and an amended or cancelled notice is not listed. Many notices are pre-scheduled under Rule 10b5-1 plans. A Form 4 with code S typically follows within a few days when the planned sale executes. Someone who is no longer an officer or director (or never was) files no Form 4, so for them a sale shows up only on a later notice, which lists the seller's sales from the 3 months before it. "No sale on file" means neither record shows one; a dash in Net $ means the value filed on the notice doesn't fit the stock's price (likely a typo).
