Check out our latest analysis for China Traditional Chinese Medicine Holdings

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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 half decade during which the share price slipped, China Traditional Chinese Medicine Holdings actually saw its earnings per share (EPS) improve by 14% 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 possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

Due to the lack of correlation between the EPS growth and the falling share price, it's worth taking a look at other metrics to try to understand the share price movement.

Revenue is actually up 31% over the time period. A more detailed examination of the revenue and earnings may or may not explain why the share price languishes; there could be an opportunity.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. In the case of China Traditional Chinese Medicine Holdings, it has a TSR of -46% 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

We regret to report that China Traditional Chinese Medicine Holdings shareholders are down 17% for the year (even including dividends) . Unfortunately, that's worse than the broader market decline of 3.8%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 12% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. It's always interesting to track share price performance over the longer term. But to understand China Traditional Chinese Medicine Holdings better, we need to consider many other factors.
