When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 16x, you may consider Keysight Technologies, Inc. (NYSE:KEYS) as a stock to avoid entirely with its 26.3x 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.

Keysight Technologies has been struggling lately as its earnings have declined faster than most other companies. It might be that many expect the dismal earnings performance to recover substantially, which has kept the P/E from collapsing. If not, then existing shareholders may be very nervous about the viability of the share price.

How Is Keysight Technologies' Growth Trending?

Keysight 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.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 4.9%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 80% in total over the last three years. Accordingly, while they would have preferred to keep the run going, shareholders would probably welcome the medium-term rates of earnings growth.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 15% each year over the next three years. That's shaping up to be materially higher than the 13% per year growth forecast for the broader market.

With this information, we can see why Keysight Technologies is trading at such a high P/E compared to the market. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Key Takeaway

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Keysight Technologies maintains its high P/E on the strength of its forecast growth being higher than the wider market, as expected. At this stage investors feel the potential for a deterioration in earnings isn't great enough to justify a lower P/E ratio. It's hard to see the share price falling strongly in the near future under these circumstances.
