AMC, the world's largest theater circuit, was a notable exception to the rally. Its stock dropped 5% on ongoing investor concern about its liquidity and a potential bankruptcy filing. At $2.38, AMC shares are at their lowest point since early November, though they are still a notch above their 2020 bottom of $1.95, established in mid-March as Covid-19 shuttered theaters across the Western hemisphere. Regal Cinemas parent Cineworld mustered just a 1% gain on the London Stock Exchange.
