GameStop popped again on Tuesday after a wild session, pushing the stock back above $140, but short sellers betting against the brick-and-mortar video game retailer are nowhere near letting up.
Shares of GameStop jumped 92.7% to $147.98 on Tuesday, after trading as high as $150 during the session. The stock turned sharply higher after Social Capital's Chamath Palihapitiya said in a tweet that he bought GameStop call options betting the stock will go higher. Trading was halted multiple times due to volatility.
The stock kept ripping higher in extended trading on Tuesday, surging more than 60%. The after-hours jump came after Elon Musk commented on the mania on Twitter and linked to the infamous "wallstreetbets" Reddit chat room with over 2 million subscribers. The Tesla CEO tweeted to his 42 million followers "Gamestonk!!"
GameStop has rallied more than 680% in January alone as an army of retail investors marshaled against short sellers in online chat rooms, encouraging each other to pile on and keep pushing the stock higher. Short sellers have amassed a mark-to-market loss of more than $5 billion year to date in the stock, including a loss of $917 million on Monday and $1.6 billion on Friday, according to data from S3 Partners.
Despite the massive squeezes, short sellers are doubling down on their bearish bets. Over the last 30 days, GameStop shares that have been borrowed and sold short increased by 1.5 million shares, worth $117 million, as its stock price more than doubled, according to S3 Partners.
Short sellers also reloaded bets over the last seven days, where shorted shares jumped by more than 900,000, worth $69 million, the data showed. GameStop's short interest stands steadily at 139%, unchanged from a week ago.
"Much like the Revolutionary War, the first line of troops goes down in a rain of musket fire, but is replaced by the troops next in line," Ihor Dusaniwsky, S3's managing director of predictive analytics, said in an email. "We are seeing a short-squeeze on older shorts who have incurred massive mark-to-market losses on their positions but are seeing new shorts coming in."
"This is keeping overall shares shorted in GME relatively flat even though there is a significant short squeeze occurring in a sizable amount of existing short sellers," Dusaniwsky added.
The explosive rally in GameStop was largely driven by the buying frenzy among individual investors active in online forums. One Reddit trending post on Tuesday features a screenshot of the user's portfolio showing an over 1,000% return on GameStop's stock.
GameStop came off a roller coaster session Monday that saw the stock more than double and turn negative within hours. The stock closed Monday up 18% at $76.79.
"The retail order flow in the options are supercharging the short squeeze," CC Lagator of Options AI said. "The call buyers essentially use the market makers' hedges as leverage. As the stocks go higher, more stock is bought to cover for increasing short deltas. It's a market inefficiency and it eventually ends when those that have sold the calls are over-hedged for a stock no longer rising, and then need to actually sell stock to stay delta neutral."
Hedge fund Melvin Capital Management, which has a short position on GameStop, has fallen 30% this year through Friday, according to The Wall Street Journal.
