When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, the Yangzhou Yangjie Electronic Technology Co., Ltd. (SZSE:300373) share price is up 92% in the last 5 years, clearly besting the market return of around 4.2% (ignoring dividends).

Since it's been a strong week for Yangzhou Yangjie Electronic Technology shareholders, let's have a look at trend of the longer term fundamentals.

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 flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, Yangzhou Yangjie Electronic Technology managed to grow its earnings per share at 17% a year. So the EPS growth rate is rather close to the annualized share price gain of 14% per year. That suggests that the market sentiment around the company hasn't changed much over that time. In fact, the share price seems to largely reflect the EPS growth.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Yangzhou Yangjie Electronic Technology the TSR over the last 5 years was 99%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market lost about 15% in the twelve months, Yangzhou Yangjie Electronic Technology shareholders did even worse, losing 26% (even including dividends). However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. Longer term investors wouldn't be so upset, since they would have made 15%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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 2 warning signs for Yangzhou Yangjie Electronic Technology you should know about.
