With a price-to-earnings (or "P/E") ratio of 33.6x ExlService Holdings, Inc. (NASDAQ:EXLS) may be sending very bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 18x and even P/E's lower than 11x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

What Are Growth Metrics Telling Us About The High P/E?

ExlService Holdings' P/E ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the market.

If we review the last year of earnings growth, the company posted a terrific increase of 21%. Pleasingly, EPS has also lifted 87% 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 ten analysts covering the company suggest earnings should grow by 11% per annum over the next three years. Meanwhile, the rest of the market is forecast to expand by 10% each year, which is not materially different.

In light of this, it's curious that ExlService Holdings' P/E sits above the majority of other companies. Apparently many investors in the company are more bullish than analysts indicate and aren't willing to let go of their stock right now. These shareholders may be setting themselves up for disappointment if the P/E falls to levels more in line with the growth outlook.
