Mercury NZ (NZSE:MCY) shareholders have earned a 8.5% CAGR over the last five years

When we invest, we're generally looking for stocks that outperform the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. To wit, the Mercury NZ share price has climbed 23% in five years, easily topping the market decline of 6.4% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 7.0%, including dividends.

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.

While Mercury NZ made a small profit, in the last year, we think that the market is probably more focussed on the top line growth at the moment. Generally speaking, we'd consider a stock like this alongside loss-making companies, simply because the quantum of the profit is so low. For shareholders to have confidence a company will grow profits significantly, it must grow revenue.

For the last half decade, Mercury NZ can boast revenue growth at a rate of 16% per year. Even measured against other revenue-focussed companies, that's a good result. While the compound gain of 4% per year is good, it's not unreasonable given the strong revenue growth. If the strong revenue growth continues, we'd hope to see the share price to follow, in time. Of course, you'll have to research the business more fully to figure out if this is an attractive opportunity.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

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 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. In the case of Mercury NZ, it has a TSR of 50% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

Mercury NZ shareholders gained a total return of 7.0% during the year. But that was short of the market average. On the bright side, the longer term returns (running at about 8% a year, over half a decade) look better. It's quite possible the business continues to execute with prowess, even as the share price gains are slowing. 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.
