Hedge fund shorting
This is a niche within a niche within a niche. The sum total of Generation trading is a whopping $350,000 a day. And we are supposed to believe hedge funds who manage hundreds of millions are dipping in here to make what, an extra $5,000 a day. Hedge funds are oceans, this is a puddle off a side brook that flows in to a pond without a name. There is no logic in that assertion. The volume will always be too small to interest people managing serious amounts of money to manipulate.
