With a price-to-earnings (or "P/E") ratio of 44.7x Quanta Services, Inc. (NYSE:PWR) 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 16x and even P/E's lower than 9x are not unusual. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Recent times have been advantageous for Quanta Services as its earnings have been rising faster than most other companies. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

Is There Enough Growth For Quanta Services?

Quanta Services' 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 59%. The latest three year period has also seen an excellent 74% overall rise in EPS, aided by its short-term performance. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

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 Quanta Services' 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.
