How Should You Interpret this?

While executives and insiders are always happy to tell you all the reasons why their stock is a buy, their actions can tell a different story about the company’s future prospects. A trend of buying activity may indicate that insiders think the stock is going up over the upcoming time period, and are trying to buy before the price rises.

Keep in mind that insider activity is only one aspect of stock research and that there are other important items to consider. I recommend you continue to research Tesaro to get a more comprehensive view of the company's fundamentals by looking at:
