Check out our latest analysis for Hankuk Carbon

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 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.

Hankuk Carbon's earnings per share are down 20% per year, despite strong share price performance over five years.

This means it's unlikely the market is judging the company based on earnings growth. Because earnings per share don't seem to match up with the share price, we'll take a look at other metrics instead.

We doubt the modest 1.1% dividend yield is attracting many buyers to the stock. In contrast revenue growth of 17% per year is probably viewed as evidence that Hankuk Carbon is growing, a real positive. In that case, the company may be sacrificing current earnings per share to drive 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Hankuk Carbon's TSR for the last 5 years was 43%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that Hankuk Carbon shareholders are down 8.5% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 3.5%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 7% 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important. Consider risks, for instance.
