Is Westinghouse Air Brake Technologies Corp. a good buy right now?

Whether Westinghouse Air Brake Technologies Corp. (WAB) looks like a good buy comes down to three things: how it is valued, how the market feels about it, and how strong the underlying business is. Each is measured against Westinghouse Air Brake Technologies Corp.'s own five-year history, so you see genuine dislocation rather than noise. Information, not advice.
