It might be of some concern to shareholders to see the Changshu Tianyin Electromechanical Co.,Ltd (SZSE:300342) share price down 14% in the last month. On the bright side the returns have been quite good over the last half decade. After all, the share price is up a market-beating 22% in that time.

Although Changshu Tianyin ElectromechanicalLtd has shed CN¥459m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During five years of share price growth, Changshu Tianyin ElectromechanicalLtd actually saw its EPS drop 21% per year.

Since the EPS are down strongly, it seems highly unlikely market participants are looking at EPS to value the company. The falling EPS doesn't correlate with the climbing share price, so it's worth taking a look at other metrics.

We doubt the modest 0.8% dividend yield is attracting many buyers to the stock. The revenue growth of 2.9% per year hardly seems impressive. So why is the share price up? It's not immediately obvious to us, but a closer look at the company's progress over time might yield answers.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Changshu Tianyin ElectromechanicalLtd, it has a TSR of 27% 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 Changshu Tianyin ElectromechanicalLtd shareholders have received a total shareholder return of 19% over the last year. That's including the dividend. That's better than the annualised return of 5% over half a decade, implying that the company is doing better recently. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
