Even after rising 15% this past week, Xinyi Electric Storage Holdings (HKG:8328) shareholders are still down 86% over the past three years

Xinyi Electric Storage Holdings Limited (HKG:8328) shareholders should be happy to see the share price up 22% in the last month. But that doesn't change the fact that the returns over the last three years have been stomach churning. To wit, the share price sky-dived 86% in that time. So it sure is nice to see a bit of an improvement. The thing to think about is whether the business has really turned around. While a drop like that is definitely a body blow, money isn't as important as health and happiness.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

However, the loss over the last year isn't as bad as the 12% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. It's always interesting to track share price performance over the longer term.
