The main aim of stock picking is to find the market-beating stocks. But the main game is to find enough winners to more than offset the losers At this point some shareholders may be questioning their investment in Portland General Electric Company (NYSE:POR), since the last five years saw the share price fall 16%.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

While the share price declined over five years, Portland General Electric actually managed to increase EPS by an average of 5.1% per year. Given the share price reaction, one might suspect that EPS is not a good guide to the business performance during the period (perhaps due to a one-off loss or gain). Or possibly, the market was previously very optimistic, so the stock has disappointed, despite improving EPS.

It's strange to see such muted share price performance despite sustained growth. Perhaps a clue lies in other metrics.

The steady dividend doesn't really explain why the share price is down. While it's not completely obvious why the share price is down, a closer look at the company's history might help explain it.

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. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. We note that for Portland General Electric the TSR over the last 5 years was 2.0%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Portland General Electric shareholders are up 13% for the year (even including dividends). But that return falls short of the market. On the bright side, that's still a gain, and it's actually better than the average return of 0.4% over half a decade This could indicate that the company is winning over new investors, as it pursues its strategy. 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.
