Investors in Aflac (NYSE:AFL) have seen splendid returns of 143% over the past five years

When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Aflac Incorporated (NYSE:AFL) share price has soared 115% in the last half decade. Most would be very happy with that. Also pleasing for shareholders was the 23% gain in the last three months.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. 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).

Over half a decade, Aflac managed to grow its earnings per share at 19% a year. So the EPS growth rate is rather close to the annualized share price gain of 17% per year. Therefore one could conclude that sentiment towards the shares hasn't morphed very much. Indeed, it would appear the share price is reacting to the EPS.

We consider it positive that insiders have made significant purchases in the last year. Even so, future earnings will be far more important to whether current shareholders make money.

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 Aflac, it has a TSR of 143% 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're pleased to report that Aflac shareholders have received a total shareholder return of 45% over one year. That's including the dividend. Since the one-year TSR is better than the five-year TSR (the latter coming in at 19% per year), it would seem that the stock's performance has improved in recent times. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity. 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.
