In just two days, Chinese electric vehicle manufacturer Nio (NYSE: NIO) is scheduled to report its first-quarter earnings– at least, according to Nasdaq.com, it is. The company hasn’t officially announced its release date yet, and other financial data providers point out that, seeing as Nio reported its Q1 earnings on May 28 in two of the past three years, it’s more likely to report closer to that date this year as well. Is there a good reason to buy Nio stock ahead of earnings?
