Shareholders in Dongbu (KRX:005960) have lost 71%, as stock drops 10% this past week

It's not possible to invest over long periods without making some bad investments. But really big losses can really drag down an overall portfolio. So consider, for a moment, the misfortune of Dongbu Corporation (KRX:005960) investors who have held the stock for three years as it declined a whopping 76%. That'd be enough to cause even the strongest minds some disquiet. And more recent buyers are having a tough time too, with a drop of 43% in the last year. Furthermore, it's down 17% in about a quarter. That's not much fun for holders. We note that the company has reported results fairly recently; and the market is hardly delighted.

After losing 10% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

Because Dongbu made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Shareholders of unprofitable companies usually desire strong revenue growth. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

Over three years, Dongbu grew revenue at 20% per year. That is faster than most pre-profit companies. So on the face of it we're really surprised to see the share price down 21% a year in the same time period. The share price makes us wonder if there is an issue with profitability. Ultimately, revenue growth doesn't amount to much if the business can't scale well. If the company is low on cash, it may have to raise capital soon.

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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Dongbu the TSR over the last 3 years was -71%, 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 4.9% in the twelve months, Dongbu shareholders did even worse, losing 40% (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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 7% per year over five years. 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. It's always interesting to track share price performance over the longer term. But to understand Dongbu better, we need to consider many other factors. Take risks, for example - Dongbu has 3 warning signs (and 1 which doesn't sit too well with us) we think you should know about.
