In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But if you try your hand at stock picking, you risk returning less than the market. Unfortunately, that's been the case for longer term Luyang Energy-Saving Materials Co., Ltd. (SZSE:002088) shareholders, since the share price is down 53% in the last three years, falling well short of the market decline of around 24%. And the ride hasn't got any smoother in recent times over the last year, with the price 31% lower in that time. But it's up 8.4% in the last week. The buoyant market could have helped drive the share price pop, since stocks are up 9.6% in the same period.

While the stock has risen 8.4% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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.

During the three years that the share price fell, Luyang Energy-Saving Materials' earnings per share (EPS) dropped by 3.2% each year. The share price decline of 22% is actually steeper than the EPS slippage. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy. This increased caution is also evident in the rather low P/E ratio, which is sitting at 11.78.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Luyang Energy-Saving Materials' TSR for the last 3 years was -46%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

While the broader market lost about 10% in the twelve months, Luyang Energy-Saving Materials shareholders did even worse, losing 27% (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 11%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
