Frontline plc (NYSE:FRO) shareholders might be concerned after seeing the share price drop 19% in the last month. But in three years the returns have been great. Indeed, the share price is up a very strong 126% in that time. After a run like that some may not be surprised to see prices moderate. Only time will tell if there is still too much optimism currently reflected in the share price.

Although Frontline has shed US$165m from its market cap this week, let's take a look at its longer term fundamental trends and see if they've driven returns.

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 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 three years of share price growth, Frontline achieved compound earnings per share growth of 119% per year. This EPS growth is higher than the 31% average annual increase in the share price. Therefore, it seems the market has moderated its expectations for growth, somewhat. This cautious sentiment is reflected in its (fairly low) P/E ratio of 7.30.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. It's always worth keeping an eye on CEO pay, but a more important question is whether the company will grow earnings throughout the years.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, Frontline's TSR for the last 3 years was 191%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

Investors in Frontline had a tough year, with a total loss of 6.5% (including dividends), against a market gain of about 32%. 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 26% 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. Consider for instance, the ever-present spectre of investment risk.
