AMC and GameStop were at the heart of a meme-stock frenzy in 2021 driven by small investors coordinating on social media.
Among other highly shorted meme stocks, Koss Corp (KOSS.O) climbed 9.5%, Bed Bath & Beyond (BBBY.O) reversed course to slip 1.3%, while the Roundhill MEME ETF (MEME.P) rose 4.2%.
"Luckily, this go around is not due to meme investors, but an actual tangible fundamental event," said David Wagner, portfolio manager at Aptus Capital Advisors.
SOURING SHORT BETSWhen there is a rush of demand from short sellers looking to exit their bearish bets amid a rise in a stock's price, it pushes prices even higher, resulting in a short squeeze.
Another favorite among retail investors - Carvana Co (CVNA.N) - jumped 22% after the used-car retailer said it expects a smaller core loss in the current quarter.
