When you buy a stock there is always a possibility that it could drop 100%. But on a lighter note, a good company can see its share price rise well over 100%. For example, the Japan Petroleum Exploration Co., Ltd. (TSE:1662) share price has soared 243% in the last half decade. Most would be very happy with that. It's also good to see the share price up 25% over the last quarter. But this could be related to the strong market, which is up 12% in the last three months.

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.

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.

During the five years of share price growth, Japan Petroleum Exploration moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. In the case of Japan Petroleum Exploration, it has a TSR of 334% 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

Japan Petroleum Exploration shareholders have received returns of 22% over twelve months (even including dividends), which isn't far from the general market return. It has to be noted that the recent return falls short of the 34% shareholders have gained each year, over half a decade. Although the share price growth has slowed, the longer term story points to a business well worth watching. It's always interesting to track share price performance over the longer term.
