Executive-Departure & Insider-Filing Signal

CEO exits are announced in an 8-K, but the tell often comes earlier: a cluster of Form 4 insider sales, a board-committee change, a quietly removed executive bio page. Markets asking whether a named executive leaves by a date are priced on speculation. You monitor the filing stream and corporate web pages for those precursors and take positions before the announcement makes it unanimous.

What you need to run it
