So shareholders might well want to know whether insiders have been buying or selling shares in Sientra, Inc. (NASDAQ:SIEN).

Most investors know that it is quite permissible for company leaders, such as directors of the board, to buy and sell stock in the company. However, such insiders must disclose their trading activities, and not trade on inside information.

Insider transactions are not the most important thing when it comes to long-term investing. But logic dictates you should pay some attention to whether insiders are buying or selling shares.
