It's not a stretch to say that OGE Energy Corp.'s (NYSE:OGE) price-to-earnings (or "P/E") ratio of 18.5x right now seems quite "middle-of-the-road" compared to the market in the United States, where the median P/E ratio is around 17x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Recent times haven't been advantageous for OGE Energy as its earnings have been falling quicker than most other companies. One possibility is that the P/E is moderate because investors think the company's earnings trend will eventually fall in line with most others in the market. You'd much rather the company wasn't bleeding earnings if you still believe in the business. Or at the very least, you'd be hoping it doesn't keep underperforming if your plan is to pick up some stock while it's not in favour.

What Are Growth Metrics Telling Us About The P/E?

In order to justify its P/E ratio, OGE Energy would need to produce growth that's similar to the market.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 6.5%. This has soured the latest three-year period, which nevertheless managed to deliver a decent 6.8% overall rise in EPS. So we can start by confirming that the company has generally done a good job of growing earnings over that time, even though it had some hiccups along the way.

Looking ahead now, EPS is anticipated to climb by 7.2% per annum during the coming three years according to the seven analysts following the company. With the market predicted to deliver 10% growth each year, the company is positioned for a weaker earnings result.

In light of this, it's curious that OGE Energy'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. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

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.

We've established that OGE Energy currently trades on a higher than expected P/E since its forecast growth is lower than the wider market. Right now we are uncomfortable with the P/E as the predicted future earnings aren't likely to support a more positive sentiment for long. Unless these conditions improve, it's challenging to accept these prices as being reasonable.

You need to take note of risks, for example - OGE Energy has 2 warning signs (and 1 which makes us a bit uncomfortable) we think you should know about.
