Global Payments Inc.'s (NYSE:GPN) price-to-earnings (or "P/E") ratio of 20.9x might make it look like a 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 as high as it is.

Global Payments certainly has been doing a good job lately as it's been growing earnings more than most other companies. The P/E is probably high because investors think this strong earnings performance will continue. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Does Growth Match The High P/E?

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

Retrospectively, the last year delivered an exceptional 59% gain to the company's bottom line. The strong recent performance means it was also able to grow EPS by 69% in total over the last three years. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Turning to the outlook, the next three years should generate growth of 17% per annum as estimated by the analysts watching the company. Meanwhile, the rest of the market is forecast to only expand by 11% each year, which is noticeably less attractive.

In light of this, it's understandable that Global Payments' 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

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.

We've established that Global Payments 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.
