Not panicking, been here a while now and seen similar things before, holding a substantial amount of shares and not letting any go. With so much good news on the horizon just seems weird, but get your point about the large order getting possibly filled.
Looks like there was 1,500,000 shares went through yesterday, but only showing up today around 12 o'clock. listed as a sell but looking at the price looks like it was actually a buy, why do they have to keep doing that ?
