In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term China Sunsine Chemical Holdings Ltd. (SGX:QES) shareholders for doubting their decision to hold, with the stock down 31% over a half decade.

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.

Check out our latest analysis for China Sunsine Chemical Holdings

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 five years over which the share price declined, China Sunsine Chemical Holdings' earnings per share (EPS) dropped by 9.8% each year. This fall in the EPS is worse than the 7% compound annual share price fall. So the market may previously have expected a drop, or else it expects the situation will improve.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, China Sunsine Chemical Holdings' TSR for the last 5 years was -15%, 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

China Sunsine Chemical Holdings shareholders are down 11% for the year (even including dividends), but the market itself is up 0.1%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 3% over the last half decade. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
