In our ongoing effort to supply you with investing insight, the following insider trades occurred this last week. Please note the disproportionate amount of selling. Now as we noted before, obviously selling is not as strong a movement indicator as buying. After all, even stakeholders can have a multitude of cash requirement reasons to sell some of their stock. Important however is to look at the volume and amount in the selling column as an indicator of what's to come.
