As an investor its worth striving to ensure your overall portfolio beats the market average. But in any portfolio, there are likely to be some stocks that fall short of that benchmark. We regret to report that long term Global Water Resources, Inc. (NASDAQ:GWRS) shareholders have had that experience, with the share price dropping 25% in three years, versus a market return of about 38%. Shareholders have had an even rougher run lately, with the share price down 12% in the last 90 days.

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.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' 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 the unfortunate three years of share price decline, Global Water Resources actually saw its earnings per share (EPS) improve by 26% 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.

Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

Revenue is actually up 9.2% over the three years, so the share price drop doesn't seem to hinge on revenue, either. This analysis is just perfunctory, but it might be worth researching Global Water Resources more closely, as sometimes stocks fall unfairly. This could present an opportunity.

It's probably worth noting that the CEO is paid less than the median at similar sized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years. So it makes a lot of sense to check out what analysts think Global Water Resources will earn in the future (free profit forecasts).

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Global Water Resources, it has a TSR of -19% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Global Water Resources shareholders are down 9.3% for the year (even including dividends), but the market itself is up 22%. 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 1.9% 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.
