The jaw-dropping rally in GameStop on Monday has already caused losses of $1 billion for short sellers, according to data from S3 Partners.
"Expect short covering in this stock as it already had a 100/100 squeeze score prior to today's trading," said Ihor Dusaniwsky, S3 managing director of predictive analytics.
Currently, the short position in GameStop shares amounts to more than 24% of all its shares that are freely available to trade, also known as the float, according to FactSet.
Including Monday's losses, short sellers in GameStop have lost $1.43 billion in May alone, according to S3.
"Short sellers may be in for a bumpy and bloody ride in these stocks," Dusaniwsky said.
