Materials sector takeaways for investors
The materials market sector presents some unique challenges for investors. Some of the top companies are based outside the U.S. and may be unfamiliar to the typical investor. Investing in international companies can be challenging since it requires learning not only about the company but also about the business climate in that particular part of the world.
In addition, the Trump administration's import tariffs are having a significant impact on the materials sector. Tariffs on building materials and precious metals lead to higher costs for many of these companies. The companies are passing the higher costs on to consumers.
However, the status of these tariffs is in doubt now that a federal appeals court has ruled most of them illegal. They're still in place for the time being, pending an appeal before the U.S. Supreme Court.
Still, whether you venture into international stocks or stick to U.S. companies, the materials sector presents plenty of quality investment opportunities. The best materials companies have excellent financials with consistent profits and reasonable debt levels. They perform best in a growing economy, but even during downturns, well-positioned materials companies can continue to make money.
