RE:RE:The hedge fund managersWhen a hedge fund covers a short they could be purchasing 10's of thousands of shares at a time off the open market at a time (100's of thousands or more is also possible). Depending on how high the SP has to go in order to complete the cover order it could result in a margin call for the piggy-backers. At short-stop over the short position is partial protection from this however holding Long Position shares to counter act the the rise in SP is the only insurance I would think is safe, options are a second option however a failure to deliever on an option holder leaves them up a creek without a paddle..
