CSPC Pharmaceutical Group Limited (HKG:1093) shareholders should be happy to see the share price up 23% in the last month. But in truth the last year hasn't been good for the share price. In fact, the price has declined 28% in a year, falling short of the returns you could get by investing in an index fund.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During the unfortunate twelve months during which the CSPC Pharmaceutical Group share price fell, it actually saw its earnings per share (EPS) improve by 11%. It could be that the share price was previously over-hyped.

It's fair to say that the share price does not seem to be reflecting the EPS growth. But we might find some different metrics explain the share price movements better.

We don't see any weakness in the CSPC Pharmaceutical Group's dividend so the steady payout can't really explain the share price drop. The revenue trend doesn't seem to explain why the share price is down. Unless, of course, the market was expecting a revenue uptick.

We like that insiders have been buying shares in the last twelve months. Even so, future earnings will be far more important to whether current shareholders make money.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, CSPC Pharmaceutical Group's TSR for the last 1 year was -25%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

CSPC Pharmaceutical Group shareholders are down 25% for the year (even including dividends), but the market itself is up 5.6%. 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 1.6% 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. 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.
