We often see insiders buying up shares in companies that perform well over the long term. 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 PTC Therapeutics, Inc. (NASDAQ:PTCT).

Do Insider Transactions Matter?

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, such insiders must disclose their trading activities, and not trade on inside information.

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 Columbia University study found that ‘insiders are more likely to engage in open market purchases of their own company’s stock when the firm is about to reveal new agreements with customers and suppliers’.

The Last 12 Months Of Insider Transactions At Therapeutics

In the last twelve months, the biggest single sale by an insider was when Chief Operating Officer Marcio Souza sold US$179k worth of shares at a price of US$34.65 per share. So we know that an insider sold shares at around the present share price of US$30.41. They could have a variety of motivations for selling, but it’s still not particularly encouraging to see. We usually pause to reflect on the potential that a stock has a high valuation, if insiders have been selling at around the current price.

In the last twelve months insiders netted US$302k for 8.71k shares sold. Over the last year we saw more insider selling of Therapeutics shares, than buying. The average sell price was around US$34.69. It’s not ideal to see that insiders have sold at around the current price. But we don’t put too much weight on the insider selling, since sellers could have personal reasons.
