York Space Systems, Inc. (YSS)

Every row is classified by what it MEANT, not by its SEC code. A code is not a meaning: code P (“purchase”) also covers dividend reinvestment and employee stock purchase plans, and code S (“sale”) also covers 10b5-1 plan sales scheduled months earlier and option exercises sold the same day.

Across 30 days of all filings, $5.08bn of insider selling contained $3.50bn of plan sales and $0.46bn of exercise-and-sell. Only 29% was discretionary. Reading an unclassified feed badly overstates how much insiders decided.

Buys and sales are counted separately and never netted. They are different decisions by different people; a company where one officer bought while another sold is not “neutral”.

The holding line carries each insider's last reported position forward, so it shows the total held rather than a sawtooth of whoever traded that day. It covers only insiders who filed in the window.

“Filed late” counts calendar days past the two-business-day deadline with five days' grace, so a Thursday or Friday trade crossing a weekend is never flagged. It describes the company's filing discipline, not the trade.

Insider activity is descriptive. Nothing here is investment advice.
