Fridays have been and always will be a typical profit taking day. When shares are up this long, you are bound to see this happen in a low volume stock. Resistance is a long ways away at 3.16 which is it's 50 DMA. I would not sell on fear.
Insiders don't buy to dump. You simply have traders taking profits after a five day run. Nothing has changed with the companies prospects. There's a reason insiders bought, and it's not because they think the stock is going down.g
