We doubt EVgo shareholders are happy with the loss of 45% over twelve months. That falls short of the market, which lost 11%. There's no doubt that's a disappointment, but the stock may well have fared better in a stronger market. It's great to see a nice little 57% rebound in the last three months. Let's just hope this isn't the widely-feared 'dead cat bounce' (which would indicate further declines to come). It's always interesting to track share price performance over the longer term. But to understand EVgo better, we need to consider many other factors. To that end, you should be aware of the 1 warning sign we've spotted with EVgo.
