Over on CAPS, some 98% of the 434 members who have rated Wabtec believe the stock will outperform the S&P 500 going forward. These bulls include naroowal99 and DepthMigration.

Three weeks ago, naroowal99 updated our community on a few positive developments:

One of the big things for Wabtec is that they are the leaders in the PTC (positive train control) technology. Congress has mandated that this technology be in the system by 2015 installed. Wabtec leads in the brake supplies and hence in the information for the brake distance. This will be $60 soon.

In a pitch from last month, DepthMigration hops aboard that bullish train of thought:

Absolutely one of my top picks. [Wabtec] is situated to take advantage of both the existing market for the rail industry by providing superior replacement/repair product, and of the future markets for more efficient rail and subway components. This is a financially conservative company, fair amount of cash on hand, and a much higher than average ROE.
