"Once the short seller borrows the shares from the lender and then sells them back into the market, the new owner of the shares is free to lend them out, just as the previous owner did, and have no idea they are on the other side of a short sale.
Settlement time is two days after the transaction. In that time, the same shares can be lent out again, and again. This makes it possible, on paper, for more than 100% of the float of a stock to be shorted.
According to financial analytics firm S3, GameStop's peak short interest was 141.8% of its float on Jan. 4."
Pokręcone, ale w USA rzeczywistości (było(?)) możliwe.
