Recent volatility in a handful of so-called meme stocks is putting the spotlight back on the tussle between individual investors and short sellers, months after a wild ride in GameStop captivated Wall Street’s attention. Stocks that have notched big swings this month include laser-manufacturer MicroVision Inc, a favorite on Reddit’s popular WallStreetBets forum, whose shares have risen as much as 170% since April 20 before tumbling in recent days. Biopharmaceutical company Ocugen Inc is up about 110% since April 20 while online video game platform Skillz, which has been added to the portfolio of Cathie Wood’s ARK funds, is up about 45%. Those moves do not approach the stunning, nearly 1,700% gain in video game retailer GameStop Corp in January, which was fueled in part by a flurry of buying that forced hedge funds like Melvin Capital to unwind their bets against the stock, sending it higher. Shares of the video game retailer and many other meme stocks that rallied in its wake are well off their highs, and retail trading has dropped from levels seen earlier in the year. “We’re seeing some return of interest to those Reddit-type stocks but not with the same pace and fervor we saw before,” said Robert Phipps, a director at Per Stirling Capital Management. Still, some market-watchers believe a smaller-scale face-off between retail investors and short sellers may have sparked part of the volatility in MicroVision and other recent movers. Average short interest in a basket of 50 stocks with market capitalization of under $100 billion monitored by Vanda Research has climbed to levels last seen in January, the firm said in a report earlier this week. At the same time, cash equity purchases and the premium spent on call options for MicroVision and some of the other gainers soared in recent weeks, an indicator of retail buying, according to analysts at Vanda, which tracks retail activity.
