Investing in Iberdrola (BME:IBE) five years ago would have delivered you a 72% gain

When we invest, we're generally looking for stocks that outperform the market average. Buying under-rated businesses is one path to excess returns. For example, long term Iberdrola, S.A. (BME:IBE) shareholders have enjoyed a 45% share price rise over the last half decade, well in excess of the market return of around 8.5% (not including dividends). However, more recent returns haven't been as impressive as that, with the stock returning just 2.5% in the last year , including dividends .

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.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

During five years of share price growth, Iberdrola achieved compound earnings per share (EPS) growth of 14% per year. The EPS growth is more impressive than the yearly share price gain of 8% over the same period. Therefore, it seems the market has become relatively pessimistic about the company.

It's probably worth noting that the CEO is paid less than the median at similar sized 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. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Iberdrola, it has a TSR of 72% for the last 5 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Iberdrola shareholders are up 2.5% for the year (even including dividends). But that was short of the market average. On the bright side, the longer term returns (running at about 11% a year, over half a decade) look better. It may well be that this is a business worth popping on the watching, given the continuing positive reception, over time, from the market. 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.
