Investing in Mercury NZ (NZSE:MCY) five years ago would have delivered you a 105% gain

Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And while active stock picking involves risks (and requires diversification) it can also provide excess returns. For example, the Mercury NZ Limited (NZSE:MCY) share price is up 70% in the last 5 years, clearly besting the market decline of around 4.5% (ignoring dividends). On the other hand, the more recent gains haven't been so impressive, with shareholders gaining just 9.2% , including dividends .

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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.

Mercury NZ's earnings per share are down 29% per year, despite strong share price performance over five years.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

On the other hand, Mercury NZ's revenue is growing nicely, at a compound rate of 9.9% over the last five years. In that case, the company may be sacrificing current earnings per share to drive growth.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Mercury NZ the TSR over the last 5 years was 105%, 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

It's good to see that Mercury NZ has rewarded shareholders with a total shareholder return of 9.2% in the last twelve months. Of course, that includes the dividend. However, that falls short of the 15% TSR per annum it has made for shareholders, each year, over five years. Potential buyers might understandably feel they've missed the opportunity, but it's always possible business is still firing on all cylinders. It's always interesting to track share price performance over the longer term. But to understand Mercury NZ better, we need to consider many other factors. Like risks, for instance.
