For many investors, the main point of stock picking is to generate higher returns than the overall market. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Luenmei Quantum Co.,Ltd (SHSE:600167) shareholders have had that experience, with the share price dropping 47% in three years, versus a market decline of about 19%.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

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 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).

During the three years that the share price fell, Luenmei QuantumLtd's earnings per share (EPS) dropped by 19% each year. The 19% average annual share price decline is remarkably close to the EPS decline. That suggests that the market sentiment around the company hasn't changed much over that time, despite the disappointment. It seems like the share price is reflecting the declining earnings per share.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Luenmei QuantumLtd, it has a TSR of -42% 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

While the broader market lost about 6.5% in the twelve months, Luenmei QuantumLtd shareholders did even worse, losing 8.2% (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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 1.4% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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 1 warning sign for Luenmei QuantumLtd you should know about.
