We wouldn't blame Insmed Incorporated (NASDAQ:INSM) shareholders if they were a little worried about the fact that William Lewis, the President recently netted about US$1.4m selling shares at an average price of US$66.73. However, that sale only accounted for 4.6% of their holding, so arguably it doesn't say much about their conviction.

Insmed Insider Transactions Over The Last Year

In fact, the recent sale by President William Lewis was not their only sale of Insmed shares this year. They previously made an even bigger sale of -US$6.4m worth of shares at a price of US$80.90 per share. While insider selling is a negative, to us, it is more negative if the shares are sold at a lower price. The good news is that this large sale was at well above current price of US$68.12. So it may not shed much light on insider confidence at current levels.

In the last year Insmed insiders didn't buy any company stock. You can see the insider transactions (by companies and individuals) over the last year depicted in the chart below. If you want to know exactly who sold, for how much, and when, simply click on the graph below!

Insider Ownership

I like to look at how many shares insiders own in a company, to help inform my view of how aligned they are with insiders. I reckon it's a good sign if insiders own a significant number of shares in the company. It's great to see that Insmed insiders own 0.9% of the company, worth about US$113m. This kind of significant ownership by insiders does generally increase the chance that the company is run in the interest of all shareholders.
