Did you know that hedge funds can short an UNLIMITED number of shares? They are not required to borrow the shares to short, they can short shares that do not exist. This enables them to create an artificial drop in share price without reason, on huge volume, and sucker the average investor into selling at artificially repressed prices.
This rips off the individual investor, and it is all legal.
The hedge funds SO need to be regulated, as they repeatedly get away with criminal behavior every day - stealing from people like you and me.
