Hedge Funds Preying On Weak Peers

"Traders play to win, and hedge funds are unconstrained by big-firm considerations, like turning your clients into your next meal is probably not a good strategy for long-term survival. But even then, brokers are widely believed to play dirty. Hedge funds avoid revealing their positions to their prime brokers (funds of any size have two or three so no one has a very good view of their activities) precisely because they assume their PB will trade against them."
