Stock pickers are generally looking for stocks that will outperform the broader market. Buying under-rated businesses is one path to excess returns. To wit, the Tianjin Pengling GroupLtd share price has climbed 63% in five years, easily topping the market return of 25% (ignoring dividends).

Since the stock has added CN¥453m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 last half decade, Tianjin Pengling GroupLtd became profitable. That's generally thought to be a genuine positive, so investors may expect to see an increasing share price.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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. In the case of Tianjin Pengling GroupLtd, it has a TSR of 68% 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

Investors in Tianjin Pengling GroupLtd had a tough year, with a total loss of 4.8% (including dividends), against a market gain of about 11%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 11%, 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 for instance, the ever-present spectre of investment risk.
