Form4 Cfo Only
In plain terms
When the CFO personally buys their own company's stock — at least $100k — the stock tends to outperform over the next 2-4 months.
How it works
CFOs have direct line-of-sight into revenue recognition, working-capital quality, off-balance-sheet exposures. Their Form-4 purchases are systematically more informative than CEO trades.

When several insiders buy their own stock within a short window (a 'cluster buy'), it's the most reliable insider signal. Sales are mostly noise.
Pre-scheduled (Rule 10b5-1) insider sales aren't bearish — but cancellations are bullish.
When a company files an 8-K under Item 5.02 (executive departures, but also appointments and pay changes), this strategy bets the stock underperforms over the next 20-90 days. Most 5.02 filings are routine, so the edge is a per-ticker hypothesis tested by our validation gates, not an established research result.
