Canacol Energy (TSE:CNE shareholders incur further losses as stock declines 12% this week, taking five-year losses to 85%

We're definitely into long term investing, but some companies are simply bad investments over any time frame. We don't wish catastrophic capital loss on anyone. For example, we sympathize with anyone who was caught holding Canacol Energy Ltd (TSE:CNE) during the five years that saw its share price drop a whopping 89%. And we doubt long term believers are the only worried holders, since the stock price has declined 54% over the last twelve months. Shareholders have had an even rougher run lately, with the share price down 32% in the last 90 days. We really feel for shareholders in this scenario. It's a good reminder of the importance of diversification, and it's worth keeping in mind there's more to life than money, anyway.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

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 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.

Over five years Canacol Energy's earnings per share dropped significantly, falling to a loss, with the share price also lower. The recent extraordinary items contributed to this situation. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But we would generally expect a lower price, given the situation.

What About The Total Shareholder Return (TSR)?

We've already covered Canacol Energy's share price action, but we should also mention its total shareholder return (TSR). The TSR attempts to capture the value of dividends (as if they were reinvested) as well as any spin-offs or discounted capital raisings offered to shareholders. Canacol Energy's TSR of was a loss of 85% for the 5 years. That wasn't as bad as its share price return, because it has paid dividends.

A Different Perspective

While the broader market gained around 19% in the last year, Canacol Energy shareholders lost 54%. 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 13% 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.
