Seems unlikely to me. Something is getting ready to happen. Beside there has been no insider selling since April after months and months of steady selling. I think I will stay long.
This kind of volume usually indicates somebody knows something and the word is getting around to family and friends.
of course, stay long, but I'm not sure the "no insider selling" is a valid point. They didn't buy either, and previously they only sold what they just received at a discounted price. No buy - No sell!
