Don’t expect a replay of the 2021 meme-stock short squeeze. Some investors are, given that short-sellers have boosted their bets against GameStop GME, -4.08% and AMC Entertainment Holdings AMC, +13.31%.
The reason I doubt another huge short squeeze is imminent traces to academic research into stocks that are most likely forming bubbles which look about to burst. During last year’s short squeeze, GME and AMC soared into bubble territory, and even though both stocks have fallen significantly since then, the deflation of their respective bubbles is most likely not yet complete.
Specifically, the professors focused on a group of stocks whose trailing 12-month returns are higher than all other publicly traded stocks, and for which relatively few shares are available in the share-lending market. That makes it harder for traders to find shares to borrow and then sell short, with the result that the normal gravitational pull exercised by short-sellers will be largely or even mostly absent.
