Odaily Planet Daily News: GameStop, an American game retailer, saw its share price surge 74% on Monday, causing heavy losses to short sellers who shorted the stock. According to data from the analysis firm S3 Partners, hedge funds that shorted GameStop lost $838 million on the day at market value. Ihor Dusaniwsky, head of predictive analysis at S3 Partners, said that before the opening of trading on Monday, GameStop's "short squeeze" score had reached a full score of 100, and a large number of short coverings were expected. The sudden surge in GameStop's share price seems to have been triggered by the internet celebrity Roaring Kitty, who encouraged retail investors to buy GameStop in large quantities in 2021, making Wall Street history. Roaring Kitty posted on the X platform for the first time since 2021, posting a photo of a gamer concentrating on the game, suggesting that the "game" has begun. In the "meme stock" craze of 2021, retail investors concentrated on long stocks that were bearish on hedge funds, forcing short sellers to cover their positions and pushing up the stock prices of these companies. According to FactSet data, more than 24% of GameStop's free float is currently shorted. According to S3 statistics, short sellers who shorted GameStop have lost $1.24 billion since May alone. Dusaniwsky pointed out that short squeeze-related buying will push up GameStop's stock price, but new short sellers are expected to enter the short market at around $30. He warned that short sellers may experience a "bumpy and bloody" market in these stocks. In addition to GameStop, other meme stocks such as AMC and Reddit also surged on Monday, with AMC up 15% and Reddit up 9%. (CNBC)
