Auren Energia (BVMF:AURE3) investors are sitting on a loss of 9.9% if they invested a year ago

Investors can approximate the average market return by buying an index fund. When you buy individual stocks, you can make higher profits, but you also face the risk of under-performance. Unfortunately the Auren Energia S.A. (BVMF:AURE3) share price slid 22% over twelve months. That's well below the market return of 14%. Auren Energia may have better days ahead, of course; we've only looked at a one year period.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with 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. 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 the last year Auren Energia saw its earnings per share drop below zero. Buyers no doubt think it's a temporary situation, but those with a nose for quality have low tolerance for losses. Of course, if the company can turn the situation around, investors will likely profit.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. As it happens, Auren Energia's TSR for the last 1 year was -9.9%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While Auren Energia shareholders are down 9.9% for the year (even including dividends), the market itself is up 14%. While the aim is to do better than that, it's worth recalling that even great long-term investments sometimes underperform for a year or more. With the stock down 9.2% over the last three months, the market doesn't seem to believe that the company has solved all its problems. Basically, most investors should be wary of buying into a poor-performing stock, unless the business itself has clearly improved. 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.
