L3Harris Technologies, Inc.'s (NYSE:LHX) price-to-earnings (or "P/E") ratio of 26.8x might make it look like a strong sell right now compared to the market in the United States, where around half of the companies have P/E ratios below 16x and even P/E's below 9x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

L3Harris Technologies certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. It seems that many are expecting the company to continue defying the broader market adversity, which has increased investors' willingness to pay up for the stock. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like L3Harris Technologies' to be considered reasonable.

Retrospectively, the last year delivered an exceptional 33% gain to the company's bottom line. The latest three year period has also seen a 29% overall rise in EPS, aided extensively by its short-term performance. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Turning to the outlook, the next three years should generate growth of 17% per year as estimated by the analysts watching the company. That's shaping up to be materially higher than the 12% per year growth forecast for the broader market.

In light of this, it's understandable that L3Harris Technologies' 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.

The Key Takeaway

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 L3Harris Technologies' analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E.
