Earnings Not Telling The Story For Armstrong World Industries, Inc. (NYSE:AWI)

With a price-to-earnings (or "P/E") ratio of 21.1x Armstrong World Industries, Inc. (NYSE:AWI) may be sending bearish signals at the moment, given that almost half of all companies in the United States have P/E ratios under 17x and even P/E's lower than 9x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the elevated P/E.

With its earnings growth in positive territory compared to the declining earnings of most other companies, Armstrong World Industries has been doing quite well of late. The P/E is probably high because investors think the company will continue to navigate the broader market headwinds better than most. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.
