The big day is approaching quickly. Chinese electric vehicle manufacturer Nio (NIO) plans to release its unaudited first-quarter 2021 financial results on April 29, after the markets close. Without a doubt, the conference call will be of great interest to the trading community. After all, NIO stock is among the most heavily traded electric vehicle (EV) stocks – not quite rivaling Tesla (TSLA), but popular nonetheless. The company has come a long way, to say the least. Just a year ago, there was talk on social media that Nio’s very existence was imperiled. Today, there’s no shortage of data to prove the skeptics wrong.
