The main aim of stock picking is to find the market-beating stocks. But in any portfolio, there will be mixed results between individual stocks. So we wouldn't blame long term Tasly Pharmaceutical Group Co., Ltd (SHSE:600535) shareholders for doubting their decision to hold, with the stock down 27% over a half decade. Furthermore, it's down 24% in about a quarter. That's not much fun for holders.

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.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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 five years over which the share price declined, Tasly Pharmaceutical Group's earnings per share (EPS) dropped by 7.2% each year. This change in EPS is reasonably close to the 6% average annual decrease in the share price. This suggests that market participants have not changed their view of the company all that much. Rather, the share price has approximately tracked EPS growth.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. We note that for Tasly Pharmaceutical Group the TSR over the last 5 years was -17%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While it's certainly disappointing to see that Tasly Pharmaceutical Group shares lost 7.1% throughout the year, that wasn't as bad as the market loss of 17%. Given the total loss of 3% per year over five years, it seems returns have deteriorated in the last twelve months. 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. It's always interesting to track share price performance over the longer term. But to understand Tasly Pharmaceutical Group better, we need to consider many other factors.
