It's both, question is which came first, his knowledge of the market or his status?Posted by seeker1972 (here)
So, a big fish sells a pile of stock. Some people say, "He didn't get rich by being dumb." So they sell all of theirs too. The stock tanks. Did the big fish see it coming? Or is the big fish the one that started the chain of trades that made it come true? Think the big fish was already in position to capitalize on this effect before he ever made the move?
I will bet it was his knowledge of the market.
