Secondly, shorting a stock that is at the bottom of its range is a way more risky proposition than shorting a stock that is at the top. GameStop closed at $3.96 on 17 July last year. Imagine you have a billion dollars in cash margin and you put on a $5,000,000 short on GameStop at different prices.
