Korea Gas' (KRX:036460) investors will be pleased with their decent 76% return over the last five years

Stock pickers are generally looking for stocks that will outperform the broader market. And in our experience, buying the right stocks can give your wealth a significant boost. To wit, the Korea Gas share price has climbed 57% in five years, easily topping the market return of 40% (ignoring dividends).

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

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 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).

During the last half decade, Korea Gas became profitable. That would generally be considered a positive, so we'd hope to see the share price to rise.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Korea Gas' TSR for the last 5 years was 76%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Korea Gas shareholders are down 13% for the year (even including dividends), but the market itself is up 27%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. On the bright side, long term shareholders have made money, with a gain of 12% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Like risks, for instance. Every company has them, and we've spotted 2 warning signs for Korea Gas (of which 1 makes us a bit uncomfortable!) you should know about.
