The main point of investing for the long term is to make money. Furthermore, you'd generally like to see the share price rise faster than the market. Unfortunately for shareholders, while the Duxton Water Limited (ASX:D2O) share price is up 16% in the last five years, that's less than the market return. Looking at the last year alone, the stock is up 8.5%.

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

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. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During five years of share price growth, Duxton Water actually saw its EPS drop 1.2% per year.

Since EPS is down a bit, and the share price is up, it's probably that the market previously had some concerns about the company, but the reality has been better than feared. In the long term, though, it will be hard for the share price rises to continue without improving EPS.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Duxton Water the TSR over the last 5 years was 47%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Duxton Water has rewarded shareholders with a total shareholder return of 14% in the last twelve months. Of course, that includes the dividend. That's better than the annualised return of 8% over half a decade, implying that the company is doing better recently. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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.
