Meme stocks are flying again in premarket trading.BlackBerry,AMC Entertainment,Sundial Growers and GameStop climbed between 2% and 28%.

BlackBerry Limited continues to see increased interest from retail investors and has now overtaken AMC Entertainment Holdings Inc. to emerge as the most-mentioned stock on Reddit’s r/WallStreetBets forum.

The moonshot surge in the shares of AMC Entertainment Holdings Inc. has vaulted it into the ranks of some of the world’s most valuable companies.

The company has gone from a small cap to a large cap in the space of a few months. A 95% gain amid a retail-trading frenzy on Wednesday left the movie-theater chain with a market capitalization of $31.3 billion. That makes it more valuable than half of the companies in the S&P 500 Index.

Paper losses from the bearish wagers on 10 of the most-shorted U.S. shares amounted to $4.5 billion Wednesday, according to Peter Hillerberg, co-founder of analytics provider Ortex. That includes $2.75 billion in unrealized losses for AMC Entertainment Holdings Inc. following the stock’s 95% surge, rising to nearly $4 billion after adding in GameStop Corp. and Bed Bath & Beyond Inc.
