Celldex Therapeutics Insider Transactions Over The Last Year

In the last twelve months, the biggest single sale by an insider was when the Senior VP & Chief Medical Officer, Diane Young, sold US$1.6m worth of shares at a price of US$35.26 per share. We generally don't like to see insider selling, but the lower the sale price, the more it concerns us. It's of some comfort that this sale was conducted at a price well above the current share price, which is US$24.98. So it may not tell us anything about how insiders feel about the current share price.

Insider Ownership

Another way to test the alignment between the leaders of a company and other shareholders is to look at how many shares they own. A high insider ownership often makes company leadership more mindful of shareholder interests. Based on our data, Celldex Therapeutics insiders have about 0.3% of the stock, worth approximately US$4.9m. I generally like to see higher levels of ownership.

So What Does This Data Suggest About Celldex Therapeutics Insiders?

It is good to see the recent insider purchase. But we can't say the same for the transactions over the last 12 months. The transactions over the last year don't give us confidence, and nor does the fairly low insider ownership, but at least the recent buying is a positive. While it's good to be aware of what's going on with the insider's ownership and transactions, we make sure to also consider what risks are facing a stock before making any investment decision.
