Shanghai Haixin Group Co., Ltd. (SHSE:600851) shareholders should be happy to see the share price up 16% in the last quarter. But that doesn't help the fact that the three year return is less impressive. In fact, the share price is down 33% in the last three years, falling well short of the market return.

Since Shanghai Haixin Group has shed CN¥374m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

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. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During the unfortunate three years of share price decline, Shanghai Haixin Group actually saw its earnings per share (EPS) improve by 6.5% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or else the company was over-hyped in the past, and so its growth has disappointed.

It's worth taking a look at other metrics, because the EPS growth doesn't seem to match with the falling share price.

With a rather small yield of just 1.1% we doubt that the stock's share price is based on its dividend. Arguably the revenue decline of 14% per year has people thinking Shanghai Haixin Group is shrinking. After all, if revenue keeps shrinking, it may be difficult to find earnings growth in the future.

A Different Perspective

Shanghai Haixin Group shareholders are down 13% for the year (even including dividends), but the market itself is up 11%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. 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.
