Pinnacle West Capital Corporation's (NYSE:PNW) Shares May Have Run Too Fast Too Soon

With earnings growth that's superior to most other companies of late, Pinnacle West Capital has been doing relatively well. One possibility is that the P/E is moderate because investors think this strong earnings performance might be about to tail off.

How Is Pinnacle West Capital's Growth Trending?

There's an inherent assumption that a company should be matching the market for P/E ratios like Pinnacle West Capital's to be considered reasonable.

If we review the last year of earnings growth, the company posted a terrific increase of 21%. Still, incredibly EPS has fallen 6.8% in total from three years ago, which is quite disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Looking ahead now, EPS is anticipated to climb by 2.0% each year during the coming three years according to the eleven analysts following the company. With the market predicted to deliver 11% growth each year, the company is positioned for a weaker earnings result.

In light of this, it's curious that Pinnacle West Capital's P/E sits in line with the majority of other companies. Apparently many investors in the company are less bearish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for future disappointment if the P/E falls to levels more in line with the growth outlook.

The Final Word

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

Our examination of Pinnacle West Capital's analyst forecasts revealed that its inferior earnings outlook isn't impacting its P/E as much as we would have predicted. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.
