S-Oil (KRX:010950) shareholders are up 4.7% this past week, but still in the red over the last five years

Ideally, your overall portfolio should beat the market average. But the main game is to find enough winners to more than offset the losers So we wouldn't blame long term S-Oil Corporation (KRX:010950) shareholders for doubting their decision to hold, with the stock down 40% over a half decade.

While the last five years has been tough for S-Oil shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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.

S-Oil became profitable within the last five years. That would generally be considered a positive, so we are surprised to see the share price is down. Other metrics may better explain the share price move.

In contrast to the share price, revenue has actually increased by 15% a year in the five year period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

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 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. We note that for S-Oil the TSR over the last 5 years was -32%, which is better than the share price return mentioned above. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that S-Oil shareholders are down 13% 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. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 6% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Take risks, for example - S-Oil has 4 warning signs (and 2 which are a bit unpleasant) we think you should know about.
