Stock pickers are generally looking for stocks that will outperform the broader market. Buying under-rated businesses is one path to excess returns. For example, long term Doctorglasses Chain Co.,Ltd. (SZSE:300622) shareholders have enjoyed a 38% share price rise over the last half decade, well in excess of the market return of around 0.5% (not including dividends).

Since the stock has added CN¥383m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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).

Over half a decade, Doctorglasses ChainLtd managed to grow its earnings per share at 13% a year. The EPS growth is more impressive than the yearly share price gain of 7% over the same period. So one could conclude that the broader market has become more cautious towards the stock.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. In the case of Doctorglasses ChainLtd, it has a TSR of 55% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

While the broader market lost about 19% in the twelve months, Doctorglasses ChainLtd shareholders did even worse, losing 28% (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. On the bright side, long term shareholders have made money, with a gain of 9% per year over half a decade. 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.
