Nio investors are worried that if XPeng is continuing to feel the pinch from strict COVID regulations in China, then Nio will, too. Both Nio and XPeng are based in China, and the Chinese government has a strict “zero-COVID” policy that requires companies, production facilities, and even cities to shut down when coronavirus cases are detected. The policy has wreaked havoc on many areas of the Chinese economy and caused massive vehicle production headaches for Nio, XPeng, Tesla, and other companies making vehicles in the country.
