With a price-to-earnings (or "P/E") ratio of 36.2x Targa Resources Corp. (NYSE:TRGP) 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. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

With earnings growth that's superior to most other companies of late, Targa Resources has been doing relatively well. The P/E is probably high because investors think this strong earnings performance will continue. If not, then existing shareholders might be a little nervous about the viability of the share price.

Does Growth Match The High P/E?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Targa Resources' to be considered reasonable.

Retrospectively, the last year delivered an exceptional 44% gain to the company's bottom line. Pleasingly, EPS has also lifted 306% 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.

Looking ahead now, EPS is anticipated to climb by 23% each year during the coming three years according to the nine analysts following the company. That's shaping up to be materially higher than the 11% per annum growth forecast for the broader market.

In light of this, it's understandable that Targa Resources' 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.

What We Can Learn From Targa Resources' P/E?

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.
