i wouldnt worry too much about it.insiders are selling all the time, it happens, new house?? new car?? what better way to finance those things by selling some shares at the peak...... 80k shares is nothing compared to what the cartens actually own, heck i have more than 80 k shares..
6 months from now we will probably be notified that insiders were buying up shares as we speak at the low before we make the next leg up.
glta.
go green!
