Optimism for Viohalco (EBR:VIO) has grown this past week, despite three-year decline in earnings

It might seem bad, but the worst that can happen when you buy a stock (without leverage) is that its share price goes to zero. But if you buy shares in a really great company, you can more than double your money. For example, the Viohalco S.A. (EBR:VIO) share price has soared 145% in the last three years. Most would be happy with that. It's also good to see the share price up 40% over the last quarter.

Since the stock has added €153m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

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. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

During the three years of share price growth, Viohalco actually saw its earnings per share (EPS) drop 9.8% per year.

So we doubt that the market is looking to EPS for its main judge of the company's value. Since the change in EPS doesn't seem to correlate with the change in share price, it's worth taking a look at other metrics.

The modest 1.7% dividend yield is unlikely to be propping up the share price. It may well be that Viohalco revenue growth rate of 3.7% over three years has convinced shareholders to believe in a brighter future. If the company is being managed for the long term good, today's shareholders might be right to hold on.

We're pleased to report that the CEO is remunerated more modestly than most CEOs at similarly capitalized companies. But while CEO remuneration is always worth checking, the really important question is whether the company can grow earnings going forward.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). 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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Viohalco's TSR for the last 3 years was 157%, which exceeds the share price return mentioned earlier. This is largely a result of its dividend payments!

A Different Perspective

It's good to see that Viohalco has rewarded shareholders with a total shareholder return of 87% in the last twelve months. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 21%. 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. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
