Long term investing can be life changing when you buy and hold the truly great businesses. While the best companies are hard to find, but they can generate massive returns over long periods. For example, the Cosmo Energy Holdings Co., Ltd. (TSE:5021) share price is up a whopping 322% in the last half decade, a handsome return for long term holders. And this is just one example of the epic gains achieved by some long term investors. It's also good to see the share price up 20% over the last quarter.

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.

In his essay The Superinvestors of Graham-and-Doddsville Warren Buffett described how share prices do not always rationally reflect the value of a business. 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, Cosmo Energy Holdings 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?

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. As it happens, Cosmo Energy Holdings' TSR for the last 5 years was 425%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Cosmo Energy Holdings provided a TSR of 26% over the year (including dividends). That's fairly close to the broader market return. It has to be noted that the recent return falls short of the 39% shareholders have gained each year, over half a decade. More recently, the share price growth has slowed. But it has to be said the overall picture is one of good long term and short term performance. Arguably that makes Cosmo Energy Holdings a stock worth watching. It's always interesting to track share price performance over the longer term. But to understand Cosmo Energy Holdings better, we need to consider many other factors.
