Further weakness as S-Oil (KRX:010950) drops 4.6% this week, taking three-year losses to 47%

As an investor its worth striving to ensure your overall portfolio beats the market average. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. We regret to report that long term S-Oil Corporation (KRX:010950) shareholders have had that experience, with the share price dropping 52% in three years, versus a market decline of about 7.3%. And over the last year the share price fell 34%, so we doubt many shareholders are delighted. The falls have accelerated recently, with the share price down 18% in the last three months. We note that the company has reported results fairly recently; and the market is hardly delighted. You can check out the latest numbers in our company report.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...'

S-Oil saw its share price decline over the three years in which its EPS also dropped, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

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. We note that for S-Oil the TSR over the last 3 years was -47%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market lost about 10% in the twelve months, S-Oil shareholders did even worse, losing 34% (even including dividends). Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% 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. 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.
