The building materials sector is currently experiencing volatility driven by trade policy uncertainties, global supply chain disruptions, and fluctuating investor sentiment, with many stocks underperforming but showing signs of recovery as interest rates decline.

This sector, which includes steel, copper, lumber, and construction chemicals, is at a critical juncture influenced by infrastructure needs, decarbonization efforts, and supply chain adjustments, offering both challenges and investment opportunities.

Proposed tariffs on materials from Mexico, China, and Canada could raise costs and complicate budgeting for construction projects, given that about one-third of construction goods rely on foreign supply chains.

Demand for materials linked to infrastructure investments, such as copper for grid modernization and electric vehicle infrastructure, is expected to increase as these projects gain momentum.
