It is not uncommon to see companies perform well in the years after insiders buy shares. The flip side of that is that there are more than a few examples of insiders dumping stock prior to a period of weak performance. So shareholders might well want to know whether insiders have been buying or selling shares in Sientra, Inc. (NASDAQ:SIEN).

What Is Insider Buying?

Most investors know that it is quite permissible for company leaders, such as directors of the board, to buy and sell stock on the market. However, most countries require that the company discloses such transactions to the market.

We would never suggest that investors should base their decisions solely on what the directors of a company have been doing. But equally, we would consider it foolish to ignore insider transactions altogether. For example, a Harvard University study found that ‘insider purchases earn abnormal returns of more than 6% per year.’
