With a price-to-earnings (or "P/E") ratio of 20.5x IDACORP, Inc. (NYSE:IDA) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 17x and even P/E's lower than 10x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's as high as it is.

IDACORP has been struggling lately as its earnings have declined faster than most other companies. One possibility is that the P/E is high because investors think the company will turn things around completely and accelerate past most others in the market. If not, then existing shareholders may be very nervous about the viability of the share price.

How Is IDACORP's Growth Trending?

The only time you'd be truly comfortable seeing a P/E as high as IDACORP's is when the company's growth is on track to outshine 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 5.9%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. Therefore, it's fair to say that earnings growth has been inconsistent recently for the company.

Turning to the outlook, the next three years should generate growth of 7.2% each year as estimated by the five analysts watching the company. That's shaping up to be materially lower than the 10% per year growth forecast for the broader market.

In light of this, it's alarming that IDACORP's P/E sits above the majority of other companies. Apparently many investors in the company are way more bullish than analysts indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as this level of earnings growth is likely to weigh heavily on the share price eventually.

The Key Takeaway

While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.

Our examination of IDACORP's analyst forecasts revealed that its inferior earnings outlook isn't impacting its high P/E anywhere near as much as we would have predicted. Right now we are increasingly uncomfortable with the high P/E as the predicted future earnings aren't likely to support such positive sentiment for long. Unless these conditions improve markedly, it's very challenging to accept these prices as being reasonable.

Don't forget that there may be other risks. For instance, we've identified 2 warning signs for IDACORP (1 makes us a bit uncomfortable) you should be aware of.

Of course, you might find a fantastic investment by looking at a few good candidates. So take a peek at this free list of companies with a strong growth track record, trading on a low P/E.
