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 before you buy or sell BioMarin Pharmaceutical Inc. (NASDAQ:BMRN), you may well want to know whether insiders have been buying or selling.

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, rules govern insider transactions, and certain disclosures are required.

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. As Peter Lynch said, 'insiders might sell their shares for any number of reasons, but they buy them for only one: they think the price will rise.'

BioMarin Pharmaceutical Insider Transactions Over The Last Year

Over the last year, we can see that the biggest insider sale was by the President of Worldwide Research & Development, Henry Fuchs, for US$2.5m worth of shares, at about US$100.00 per share. While we don't usually like to see insider selling, it's more concerning if the sales take price at a lower price. It's of some comfort that this sale was conducted at a price well above the current share price, which is US$82.72. So it may not shed much light on insider confidence at current levels.

In the last twelve months insiders netted US$4.4m for 44416 shares sold. Insiders in BioMarin Pharmaceutical didn't buy any shares in the last year.
