Port of Tauranga (NZSE:POT) jumps 4.2% this week, though earnings growth is still tracking behind five-year shareholder returns

When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. To wit, the Port of Tauranga share price has climbed 53% in five years, easily topping the market return of 26% (ignoring dividends).

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

Check out our latest analysis for Port of Tauranga

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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.

Over half a decade, Port of Tauranga managed to grow its earnings per share at 6.1% a year. This EPS growth is lower than the 9% average annual increase in the share price. This suggests that market participants hold the company in higher regard, these days. And that's hardly shocking given the track record of growth.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Port of Tauranga, it has a TSR of 80% 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

We regret to report that Port of Tauranga shareholders are down 12% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 5.8%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 12% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. Investors who like to make money usually check up on insider purchases, such as the price paid, and total amount bought.
