I watch insider sales too. IMHO, I think most of the recent DKS sales are not a negative sign. Most appear to be the exercising of very low cost options. Also, most were before congress extended the 15% tax rate for capital gains.
As a side note, I see that our Mr. Bling couldn't resist the opportunity to diss you and brag on himself. Gotta love shorts like him - but he gives most shorts a bad name!
