I don't know a lot about stocks, but I do have a question:If I had been short ACHN, and it just went up about 50% in the past few days, would I have lost money?
cmon seriously. Are you new to the stock market. If it did go up 50% you would lose any money. Short it tommorrow!!
Yes... if you are not sure what you are doing then don't short. Shorting a potential take out target can burn you if you can't cover prior to buyout. Check out the pain on the inhx board.
When your Broker called you to Replace your Borrowed Shares for the Short Squeeze then yes you can loose ALOT of Money, You can lose 2 x 3x 10 x your Money if the PPS continues to go up and you have not Covered
...yea, Me Too!!
