RTX Corporation's (NYSE:RTX) price-to-earnings (or "P/E") ratio of 43.3x 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 17x and even P/E's below 10x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

With earnings that are retreating more than the market's of late, RTX has been very sluggish. 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.

Is There Enough Growth For RTX?

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

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 34%. At least EPS has managed not to go completely backwards from three years ago in aggregate, thanks to the earlier period of growth. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Looking ahead now, EPS is anticipated to climb by 32% per annum during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to only expand by 10% each year, which is noticeably less attractive.

In light of this, it's understandable that RTX's P/E sits above the majority of other companies. Apparently shareholders aren't keen to offload something that is potentially eyeing a more prosperous future.

The Key Takeaway

Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that RTX 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. Unless these conditions change, they will continue to provide strong support to the share price.
