the most recent I see (6/7 I think ) was acquiring more shares. How recent are you talking about..like last 2-3 days?
But the old argument is that there are many reasons for insiders to sell but only one to buy.
But you know, I kinda disagree with the only reason to buy idea. I think sometimes insiders buy to protect their jobs by reducing the number of shares on the market that could fall into "unfriendly" hands. In essence the insider is protecting his or her job!
