Except shorts pay borrow fees but longs can hold indefinitely for free. Borrow fees on $GME often go as high as 80%
Shall be an interesting week.
Edit: looks like it's already falling apart, the price is down 30% on post-market trading! Expect things to get real once the market opens up.
Is that true? I tried and failed to verify.
Shorting a stock at $300, when it was trading at $16 last month is pretty much the definition of huge upside.
Note that if you short at 300 and it flash jumps to 1000 you are toast.
