Investing can be hard but the potential fo an individual stock to pay off big time inspires us. But when you hold the right stock for the right time period, the rewards can be truly huge. For example, the Huaming Power Equipment Co.,Ltd (SZSE:002270) share price is up a whopping 364% in the last three years, a handsome return for long term holders. It's also good to see the share price up 24% over the last quarter.

Since the stock has added CN¥878m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Huaming Power EquipmentLtd was able to grow its EPS at 44% per year over three years, sending the share price higher. In comparison, the 67% per year gain in the share price outpaces the EPS growth. This indicates that the market is feeling more optimistic on the stock, after the last few years of progress. That's not necessarily surprising considering the three-year track record of earnings growth.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Huaming Power EquipmentLtd, it has a TSR of 439% for the last 3 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 Huaming Power EquipmentLtd shareholders have received a total shareholder return of 109% over the last year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 35% per year), it would seem that the stock's performance has improved in recent times. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
