Investing in Port of Tauranga (NZSE:POT) five years ago would have delivered you a 66% gain

Generally speaking the aim of active stock picking is to find companies that provide returns that are superior to the market average. And the truth is, you can make significant gains if you buy good quality businesses at the right price. For example, long term Port of Tauranga Limited (NZSE:POT) shareholders have enjoyed a 41% share price rise over the last half decade, well in excess of the market return of around 10% (not 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.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During five years of share price growth, Port of Tauranga achieved compound earnings per share (EPS) growth of 6.1% per year. This EPS growth is reasonably close to the 7% average annual increase in the share price. This indicates that investor sentiment towards the company has not changed a great deal. Rather, the share price has approximately tracked EPS growth.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Port of Tauranga's TSR for the last 5 years was 66%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

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 9.9%. 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. Longer term investors wouldn't be so upset, since they would have made 11%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering.
