Shares of the Chinese electric vehicle (EV) maker Nio (NYSE: NIO) were falling this morning on seemingly no company-specific news. Instead, the EV stock is likely falling as the broader market responds to soaring inflation and the Federal Reserve's aggressive interest rate hikes. Investors are getting increasingly concerned about the potential for a global recession, and that sentiment is likely contributing to Nio's share price decline today. The stock fell by as much as 4.9% today and was down by 2.5% as of 11:09 a.m. ET.
