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.

Looking back five years, both Bestsun Energy's share price and EPS declined; the latter at a rate of 6.2% per year. Readers should note that the share price has fallen faster than the EPS, at a rate of 17% per year, over the period. So it seems the market was too confident about the business, in the past.

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 Bestsun Energy, it has a TSR of -48% for the last 5 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

It's nice to see that Bestsun Energy shareholders have received a total shareholder return of 1.6% over the last year. That's including the dividend. That certainly beats the loss of about 8% per year over the last half decade. The long term loss makes us cautious, but the short term TSR gain certainly hints at a brighter future. 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.
