(CNN) — GameStop traders sent the stock on a wild ride Thursday, and it looks set for another manic session Friday.
The stock lost more than 44% of its value on Thursday after surging nearly 40% at one point earlier in the day. Adding to the drama? The trading platform Robinhood restricted trading in the red hot stock as well as several others.
“We continuously monitor the markets and make changes where necessary. In light of recent volatility, we are restricting transactions for certain securities to position closing only,” Robinhood said in a statement, adding that it was also doing so for AMC, BlackBerry, Bed Bath & Beyond, Nokia and three other stocks.
“Amid significant market volatility, it’s important as ever that we help customers stay informed,” Robinhood added.
The backlash was swift, and hours after implementing the restrictions, Robinhood said it would resume limited buys on those securities starting Friday. GameStop shares surged in premarket trading Friday, gaining 100% as of 4 a.m. ET.
“This was a risk-management decision, and was not made on the direction of the market makers we route to,” Robinhood said in a blog post. “We’re beginning to open up trading for some of these securities in a responsible manner.”
Shares of GameStop fell more than 60% at one point and were halted several times Thursday, after having soared in recent weeks because of support from individual investors on Reddit. The stock was flat about ten minutes after the market opened.
Two exchange-traded funds with significant positions in GameStop plunged Thursday too. The Wedbush ETFMG Video Game Tech ETF and SPDR S&P Retail ETF both fell about 10%, but each of them are still up more than 25% so far this year.
Despite the losses Thursday, GameStop shares are still up nearly 950% in 2021 — surging from just under $20 at the end of 2020 to a current price of about $195. It’s largely because of an army of investors who are buying the stock to hurt hedge funds that have bet against GameStop.
The phenomenon is called a short squeeze. An investor who thinks a stock will fall borrows the shares and sells them, with the hopes of buying them back at a lower price and pocketing the difference before paying back the loan.
The problem is that a short seller can be hurt if the stock they borrowed keeps climbing. The losses, in theory, are infinite. So that creates another buying frenzy as short sellers rush to buy back the stock before it moves even higher.
A community on Reddit called Wall Street Bets has been leading the charge against the short sellers. Experts say that the rise of no-fee trading due to the popularity of online brokers such as Robinhood just makes it even easier for individual investors to keep plowing into GameStop stock.
The GameStop phenomenon has taken Wall Street — and all of America for that matter — by storm. The White House has said it is looking into the stock’s massive surge. Federal Reserve chair Jerome Powell was asked about it during a press conference Wednesday.
It’s unclear how much longer this short squeeze can last. Online brokerage TD Ameritrade, which is now owned by Charles Schwab, has started to limit trading in GameStop and other shares that have also gotten a pop from the Reddit crowd, such as movie theater chain AMC.
And Wells Fargo’s financial advisory unit has banned employees from making recommendations to clients about GameStop and AMC.
The big concern is that average investors may be ignoring longer-term risks about GameStop as they look for a quick short-term pop.
Although the retailer reported decent holiday results and now has the backing of Chewy co-founder Ryan Cohen, GameStop is still losing money as the sales of video games have increasingly shifted from buying a cartridge in a box at a physical store to a download model.
“GameStop shares are trading completely untethered from fundamentals and that is dangerous,” David Trainer, CEO of New Constructs, an investment research firm, said in an email to CNN Business.
