In 2021, the bulls became pigs when they ignored the looming threat of inflation and rising interest rates. Two such stocks are the online lender Upstart (NASDAQ: UPST) and the plant-based meat producer Beyond Meat (NASDAQ: BYND), which still had 31% and 35% of their outstanding shares, respectively, being shorted as of Jan. 12. Upstart's artificial-intelligence (AI) powered lending platform helps banks, credit unions, and auto dealerships approve loans with nontraditional data points like a person's education, grade-point average, standardized test scores, and work history.
