Rivian Automotive (NASDAQ: RIVN) and Nio (NYSE: NIO) are among the most closely followed electric vehicle (EV) stocks. While Nio is a key player in the world’s largest EV market, China, Rivian stole the spotlight when it beat legacy automakers and became the first company to launch an all-electric pickup truck, the R1T. The markets, however, haven’t been kind to Rivian and Nio.
