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 the bright side, you can make far more than 100% on a really good stock. One great example is Aflac Incorporated (NYSE:AFL) which saw its share price drive 151% higher over five years.

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.

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 imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Over half a decade, Aflac managed to grow its earnings per share at 4.5% a year. This EPS growth is lower than the 20% average annual increase in the share price. So it’s fair to assume the market has a higher opinion of the business than it did five years ago. And that’s hardly shocking given the track record of growth.

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 Aflac, it has a TSR of 182% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

Aflac provided a TSR of 9.5% over the last twelve months. But that return falls short of the market. It’s probably a good sign that the company has an even better long term track record, having provided shareholders with an annual TSR of 23% over five years. Maybe the share price is just taking a breather while the business executes on its growth strategy. Most investors take the time to check the data on insider transactions.
