When a single insider purchases stock, it is typically not a major deal. However, when multiple insiders purchase stock, like in Generation Bio Co.'s (NASDAQ:GBIO) instance, it's good news for shareholders.

While we would never suggest that investors should base their decisions solely on what the directors of a company have been doing, we do think it is perfectly logical to keep tabs on what insiders are doing.
