The five-year underlying earnings growth at Colbún (SNSE:COLBUN) is promising, but the shareholders are still in the red over that time

In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term Colbún S.A. (SNSE:COLBUN) shareholders for doubting their decision to hold, with the stock down 63% over a half decade.

After losing 6.1% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

While the share price declined over five years, Colbún actually managed to increase EPS by an average of 28% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Alternatively, growth expectations may have been unreasonable in the past.

Because of the sharp contrast between the EPS growth rate and the share price growth, we're inclined to look to other metrics to understand the changing market sentiment around the stock.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. It's not immediately clear to us why the stock price is down but further research might provide some answers.

It is of course excellent to see how Colbún has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at Colbún's financial health with this free report on its balance sheet.

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 incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Colbún, it has a TSR of -12% for the last 5 years. That exceeds its share price return that we previously mentioned. This is largely a result of its dividend payments!

A Different Perspective

We regret to report that Colbún shareholders are down 17% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 4.7%. 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 2% over the last half decade. 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.
