When close to half the companies in the United States have price-to-earnings ratios (or "P/E's") below 18x, you may consider Westinghouse Air Brake Technologies Corporation (NYSE:WAB) as a stock to avoid entirely with its 31x P/E ratio. 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, Westinghouse Air Brake Technologies has been doing relatively well. It seems that many are expecting the strong earnings performance to persist, which has raised the P/E. If not, then existing shareholders might be a little nervous about the viability of the share price.
