FirstEnergy Corp.'s (NYSE:FE) price-to-earnings (or "P/E") ratio of 23.5x might make it look like a sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 17x and even P/E's below 10x are quite common. However, the P/E might be high for a reason and it requires further investigation to determine if it's justified.

FirstEnergy hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

The only time you'd be truly comfortable seeing a P/E as high as FirstEnergy's is when the company's growth is on track to outshine the market.

Retrospectively, the last year delivered a frustrating 13% decrease to the company's bottom line. The last three years don't look nice either as the company has shrunk EPS by 25% in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Shifting to the future, estimates from the ten analysts covering the company suggest earnings should grow by 21% per year over the next three years. That's shaping up to be materially higher than the 11% each year growth forecast for the broader market.

In light of this, it's understandable that FirstEnergy's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

What We Can Learn From FirstEnergy's P/E?

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

As we suspected, our examination of FirstEnergy's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio.
