When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 19x, you may consider Agilent Technologies, Inc. (NYSE:A) as a stock to avoid entirely with its 31.2x P/E ratio. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

With earnings growth that's superior to most other companies of late, Agilent Technologies has been doing relatively well. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

Agilent Technologies' P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

Taking a look back first, we see that the company managed to grow earnings per share by a handy 5.4% last year. EPS has also lifted 14% in aggregate from three years ago, partly thanks to the last 12 months of growth. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 12% per year during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to expand by 11% each year, which is not materially different.

In light of this, it's curious that Agilent Technologies' P/E sits above the majority of other companies. It seems most investors are ignoring the fairly average growth expectations and are willing to pay up for exposure to the stock. Although, additional gains will be difficult to achieve as this level of earnings growth is likely to weigh down the share price eventually.

The Final Word

Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

Our examination of Agilent Technologies' analyst forecasts revealed that its market-matching earnings outlook isn't impacting its high P/E as much as we would have predicted. Right now we are uncomfortable with the relatively high share price as the predicted future earnings aren't likely to support such positive sentiment for long. This places shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.

Many other vital risk factors can be found on the company's balance sheet. Our free balance sheet analysis for Agilent Technologies with six simple checks will allow you to discover any risks that could be an issue.
