Right, I see your point... I'm new and make incorrect assumptions. Shorters borrow money on anticipation that a stock will decrease in value so any increase would be bad. For example, if a shorter "buys" a short position of 100 shares at $10 per shares and is lucky enough to sell the shorted stock at $8 per share then he just made $200.
However, the scary thing for a shorter is if the stock sky rockets to $100 per share then he has to come up with $10,000???
What happens when they all just run out of money and declare bankruptcy? Do we still get our money!?!?
