How to read insider trades
Officers, directors and owners of more than 10% of a company must report trades in its stock on SEC Form 4, usually within two business days. Purchases with their own money are the stronger signal: insiders sell for many reasons (taxes, diversification, a house), but buy for one. See every AMTB insider trade, the latest insider trades across the market, or cluster buys, when several insiders buy the same stock within days.
