Insiders were net buyers of Celldex Therapeutics, Inc.'s (NASDAQ:CLDX ) stock during the past year. That is, insiders bought more stock than they sold.

Although we don't think shareholders should simply follow insider transactions, logic dictates you should pay some attention to whether insiders are buying or selling shares.

Celldex Therapeutics Insider Transactions Over The Last Year

The Founder Anthony Marucci made the biggest insider purchase in the last 12 months. That single transaction was for US$308k worth of shares at a price of US$26.82 each. That means that an insider was happy to buy shares at above the current price of US$20.92. It's very possible they regret the purchase, but it's more likely they are bullish about the company. To us, it's very important to consider the price insiders pay for shares. As a general rule, we feel more positive about a stock when an insider has bought shares at above current prices, because that suggests they viewed the stock as good value, even at a higher price. Anthony Marucci was the only individual insider to buy during the last year.
