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.
