Did Seattle Genetics, Inc. (NASDAQ:SGEN) Insiders Sell Shares?

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 Seattle Genetics, Inc. (NASDAQ:SGEN).

What Is Insider Selling?

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, most countries require that the company discloses such transactions to the market.

We don't think shareholders should simply follow insider transactions. But logic dictates you should pay some attention to whether insiders are buying or selling shares. For example, a Harvard University study found that 'insider purchases earn abnormal returns of more than 6% per year'.
