Extension of Cohen-Malloy-Pomorski (2012) "Decoding Inside Information" cluster pattern to Form 144 planned-sale filings.

In plain terms

When 2+ insiders file paperwork to sell within 14 days of each other, the coordinated planned-exit signal tends to mark short-term tops.

How it works

Concurrent Form 144 filings by >=2 distinct insiders within 14d are a stronger negative-drift signal than a single filer; multi-insider coordination strips idiosyncratic-liquidity noise and corroborates the planned-exit signal.
