Shenzhen Aisidi's (SZSE:002416) investors will be pleased with their impressive 159% return over the last five years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on a lighter note, a good company can see its share price rise well over 100%. For instance, the price of Shenzhen Aisidi Co., Ltd. (SZSE:002416) stock is up an impressive 104% over the last five years. On top of that, the share price is up 64% in about a quarter. But this could be related to the strong market, which is up 28% in the last three months.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, Shenzhen Aisidi managed to grow its earnings per share at 84% a year. The EPS growth is more impressive than the yearly share price gain of 15% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Shenzhen Aisidi, it has a TSR of 159% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that Shenzhen Aisidi shareholders have received a total shareholder return of 78% over the last year. Of course, that includes the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 21% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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. Consider risks, for instance. Every company has them, and we've spotted 3 warning signs for Shenzhen Aisidi you should know about.
