VC, Understood. It's a crapshoot, as they say. Still, one never knows why another trades out. I've done that recently to buy more shares...sold a stock that I've held for awhile with positive expectations to allow me to buy more here. It could be the same for the large seller you propose, perhaps he see this as a tad longer than he'd like and is closing out to move to another, more recent play. Perhaps they've bought a the low pennies are and can move out with a 3 to 5x gain.
Still, there's a boatload of other shares out there, and there doesn't seem to have been a massive dumping as one would expect to see with negative expectations. DD, gut feel and a smidgen of Fred's cheerleading have left me with a very positive outlook here. Just waitng, as do we all.
