Ideally, your overall portfolio should beat the market average. But even the best stock picker will only win with some selections. At this point some shareholders may be questioning their investment in Shanghai Construction Group Co., Ltd. (SHSE:600170), since the last five years saw the share price fall 35%.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

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).

Looking back five years, both Shanghai Construction Group's share price and EPS declined; the latter at a rate of 10% per year. This fall in the EPS is worse than the 8% compound annual share price fall. So investors might expect EPS to bounce back -- or they may have previously foreseen the EPS decline.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Shanghai Construction Group, it has a TSR of -21% for the last 5 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

Although it hurts that Shanghai Construction Group returned a loss of 12% in the last twelve months, the broader market was actually worse, returning a loss of 15%. Given the total loss of 4% per year over five years, it seems returns have deteriorated in the last twelve months. Whilst Baron Rothschild does tell the investor "buy when there's blood in the streets, even if the blood is your own", buyers would need to examine the data carefully to be comfortable that the business itself is sound. 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.
