Shanghai Aj Group Co.,Ltd (SHSE:600643) shareholders should be happy to see the share price up 18% in the last month. But if you look at the last five years the returns have not been good. You would have done a lot better buying an index fund, since the stock has dropped 48% in that half decade.

Although the past week has been more reassuring for shareholders, they're still in the red over the last five years, so let's see if the underlying business has been responsible for the decline.

There is no denying that markets are sometimes efficient, but prices do not always reflect 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).

In the last half decade Shanghai Aj GroupLtd saw its share price fall as its EPS declined below zero. The recent extraordinary items contributed to this situation. At present it's hard to make valid comparisons between EPS and the share price. But we would generally expect a lower price, given the situation.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. As it happens, Shanghai Aj GroupLtd's TSR for the last 5 years was -41%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While it's certainly disappointing to see that Shanghai Aj GroupLtd shares lost 15% throughout the year, that wasn't as bad as the market loss of 19%. Unfortunately, last year's performance may indicate unresolved challenges, given that it's worse than the annualised loss of 7% over the last half decade. 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. 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.
