President Trump stick to his presidential campaign promise and signed an executive order on Wednesday, January 25, 2017 to build massive wall along the Mexican border. The border wall announcement was seemed offensive to the NAFTA partner south of the border and resulted in an immediate cancellation of the meeting of Mexican president Enrique Peña Nieto with president Trump. However there are companies that could stand to benefit from this massive undertaking.

As mentioned in The Street's recent article, two companies getting immediate revenue boost could be current fencing contractors Granite Construction(GVA) and Tetra Tech(TTEK). Also benefiting from the Mexican Border Wall are contractors maintaining the wall including Fluor (FLR) and KBR (KBR).

If the wall is to be constructed with hardened concrete, rebar and steel and promised by Trump, materials and steels companies including Martin Marietta Materials(MLM), Eagle Marterials(EXP), U.S. Steel (X) , Nucor (NUE) and Steel Dynamics (STLD) would receive the benefit as well as construction equipment companies Deere & Co. (DE) and Caterpillar (CAT).

In addition to the materials of the wall itself, Elbit Systems (ESLT) who implemented the surveillance system along the border in Arizona would be a company not to miss.

Below are the list of stocks to watch for the Mexico Border Wall.
