Is Wabtec (WAB) Still Undervalued After Its Recent Share Price Strength?

Westinghouse Air Brake Technologies (WAB) has quietly turned into a long term compounder, and the recent move in the stock is a good excuse to revisit how its fundamentals stack up.

See our latest analysis for Westinghouse Air Brake Technologies.

The latest move to a share price of $208.38 caps a steady run, with a roughly mid single digit 90 day share price return and a triple digit three year total shareholder return. This signals that the long term momentum story is still very much intact.

If WabTech’s trajectory has you thinking about where else durable growth might be hiding, this could be a good moment to explore aerospace and defense stocks as potential next candidates.

With double digit earnings growth and the share price brushing up against analyst targets, the key question now is whether WabTech still trades below its true worth or if the market has already priced in years of expansion.
