Shareholders in Calidus Resources (ASX:CAI) have lost 78%, as stock drops 16% this past week

Every investor on earth makes bad calls sometimes. But really big losses can really drag down an overall portfolio. So take a moment to sympathize with the long term shareholders of Calidus Resources Limited (ASX:CAI), who have seen the share price tank a massive 78% over a three year period. That might cause some serious doubts about the merits of the initial decision to buy the stock, to put it mildly. And more recent buyers are having a tough time too, with a drop of 77% in the last year. The falls have accelerated recently, with the share price down 35% 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.

Calidus Resources wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last three years, Calidus Resources saw its revenue grow by 159% per year, compound. That is faster than most pre-profit companies. So why has the share priced crashed 21% per year, in the same time? 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.

A Different Perspective

While the broader market gained around 7.3% in the last year, Calidus Resources shareholders lost 77%. 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. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 9% per year over five years. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. 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.
