Why it moves the price
Insiders sell for many reasons but buy for one. Clustered open-market purchases are a credible signal that the people with the best information think the stock is cheap.
What separates a good call from a naive one
Distinguish real open-market purchases from option exercises and scheduled 10b5-1 plans. Meaningful buys are large relative to the insider's own compensation, and made by operators (CEO/CFO) rather than a single director.
Measured impact
