The last twelve months weren't great for ChargePoint Holdings shares, which cost holders 37%, while the market was up about 20%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. The three-year loss of 3% per year isn't as bad as the last twelve months, suggesting that the company has not been able to convince the market it has solved its problems. We would be wary of buying into a company with unsolved problems, although some investors will buy into struggling stocks if they believe the price is sufficiently attractive. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Case in point: We've spotted 3 warning signs for ChargePoint Holdings you should be aware of, and 1 of them is concerning.
