Investors in Public Power (ATH:PPC) have seen strong returns of 190% over the past three years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But in contrast you can make much more than 100% if the company does well. For instance the Public Power Corporation S.A. (ATH:PPC) share price is 176% higher than it was three years ago. How nice for those who held the stock! It's also good to see the share price up 26% over the last quarter.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

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. 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.

During three years of share price growth, Public Power moved from a loss to profitability. Given the importance of this milestone, it's not overly surprising that the share price has increased strongly.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Public Power the TSR over the last 3 years was 190%, 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

It's good to see that Public Power has rewarded shareholders with a total shareholder return of 56% in the last twelve months. And that does include the dividend. That gain is better than the annual TSR over five years, which is 20%. Therefore it seems like sentiment around the company has been positive lately. Someone with an optimistic perspective could view the recent improvement in TSR as indicating that the business itself is getting better with time. 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.
