Electric Power Development (TSE:9513) shareholders have earned a 22% CAGR over the last 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 Electric Power Development Co., Ltd. (TSE:9513) share price has soared 121% in the last half decade. Most would be very happy with that. It's also good to see the share price up 11% over the last quarter. But this move may well have been assisted by the reasonably buoyant market (up 6.6% in 90 days).

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, Electric Power Development managed to grow its earnings per share at 18% a year. This EPS growth is reasonably close to the 17% average annual increase in the share price. This indicates that investor sentiment towards the company has not changed a great deal. In fact, the share price seems to largely reflect the 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. 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Electric Power Development, it has a TSR of 171% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Electric Power Development's TSR for the year was broadly in line with the market average, at 27%. That gain looks pretty satisfying, and it is even better than the five-year TSR of 22% per year. It is possible that management foresight will bring growth well into the future, even if the share price slows down. It's always interesting to track share price performance over the longer term.
