Corporate insiders such as executives, directors and major shareholders may buy or sell shares of companies with which they are affiliated. These transactions can give investors another way to monitor changes in insider ownership, but a purchase or sale does not by itself explain why the insider traded or predict where the stock is headed.
MarketBeat's Insider Trading Activity tracker brings together recently reported insider purchases and sales and shows details such as the insider's role, transaction size, transaction date and shares held after the transaction. Investors can use the data to look for patterns such as repeated purchases, multiple insiders trading around the same period or unusually large changes in ownership.
For U.S. companies, many transactions by officers, directors and shareholders who own more than 10% of a class of registered equity securities are reported through SEC Forms 3, 4 and 5. Most reportable transactions appear on Form 4 within two business days after the transaction.
