Biopharmaceutical company Liquidia Technologies (LQDA) has seen two corporate insiders pull the trigger on shares in the past week. Insiders such as corporate officers and board members know the companies they manage inside and out. However, these people in the know are required by law to disclose their trades in order to level the playing field. So, following insider activity can be a helpful strategy for investors. On April 13, Liquidia Directors Paul Manning and Roger Jeffs purchased shares of the company. While Manning acquired 198,413 shares worth about $500,000, Jeffs acquired 99,206 shares worth about $250,000.
