The U.S. Department of Defense has also awarded the company a $50 billion umbrella contract in a 20-year agreement to support the Patriot missile defense system, as well as a $5 billion contract for its Coyote missile system.

The Trump administration's import tariffs also pose a potential problem for industrial companies, though their status often changes. Still, considering how essential top industrial companies are to the economy, it makes sense to have some in an investment portfolio.
