Equifax Inc.'s (NYSE:EFX) price-to-earnings (or "P/E") ratio of 63.5x 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 18x 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.

Recent times have been pleasing for Equifax as its earnings have risen in spite of the market's earnings going into reverse. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. If not, then existing shareholders might be a little nervous about the viability of the share price.

Keen to find out how analysts think Equifax's future stacks up against the industry? In that case, our free report is a great place to start.

Does Growth Match The High P/E?

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

If we review the last year of earnings growth, the company posted a worthy increase of 10%. Still, lamentably EPS has fallen 20% in aggregate from three years ago, which is disappointing. Therefore, it's fair to say the earnings growth recently has been undesirable for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 35% per year over the next three years. That's shaping up to be materially higher than the 10% per annum growth forecast for the broader market.

With this information, we can see why Equifax 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.

What We Can Learn From Equifax's P/E?

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of Equifax's analyst forecasts revealed that its superior earnings outlook is contributing to its high P/E. Right now shareholders are comfortable with the P/E as they are quite confident future earnings aren't under threat. It's hard to see the share price falling strongly in the near future under these circumstances.
