Fiserv, Inc.'s (NYSE:FI) price-to-earnings (or "P/E") ratio of 26.7x 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. 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 Fiserv as its earnings have risen in spite of the market's earnings going into reverse. 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. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

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

Taking a look back first, we see that the company grew earnings per share by an impressive 50% last year. Pleasingly, EPS has also lifted 270% in aggregate from three years ago, thanks to the last 12 months of growth. Therefore, it's fair to say the earnings growth recently has been superb for the company.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 19% each year over the next three years. With the market only predicted to deliver 13% per year, the company is positioned for a stronger earnings result.

In light of this, it's understandable that Fiserv's 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.
