In order to justify the effort of selecting individual stocks, it's worth striving to beat the returns from a market index fund. But even the best stock picker will only win with some selections. 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 22%. Unfortunately the share price momentum is still quite negative, with prices down 8.3% in thirty days. However, we note the price may have been impacted by the broader market, which is down 3.5% in the same time period.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

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 7.5% 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 is unusual to see such modest share price growth in the face of sustained EPS improvements. We can look to other metrics to try to understand the situation better.

We note that the dividend has remained healthy, so that wouldn't really explain the share price drop. 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. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Portland General Electric, it has a TSR of -5.3% 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

Portland General Electric provided a TSR of 2.1% over the last twelve months. But that return falls short of the market. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 1.0% endured over half a decade. It could well be that the business is stabilizing. 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.
