Cachet Pharmaceutical Co., Ltd. (SZSE:002462) shareholders should be happy to see the share price up 11% in the last month. But that doesn't change the fact that the returns over the last five years have been less than pleasing. You would have done a lot better buying an index fund, since the stock has dropped 29% 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.

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. 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.

While the share price declined over five years, Cachet Pharmaceutical actually managed to increase EPS by an average of 2.6% 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). Alternatively, growth expectations may have been unreasonable in the past.

By glancing at these numbers, we'd posit that the the market had expectations of much higher growth, five years ago. Having said that, we might get a better idea of what's going on with the stock by looking at other metrics.

Revenue is actually up 13% 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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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 Cachet Pharmaceutical the TSR over the last 5 years was -22%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's good to see that Cachet Pharmaceutical has rewarded shareholders with a total shareholder return of 24% in the last twelve months. And that does include the dividend. There's no doubt those recent returns are much better than the TSR loss of 4% per year over five years. This makes us a little wary, but the business might have turned around its fortunes. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
