12 Best Mid-Cap Materials Stocks to Buy Now

In this article, we will take a look at the 12 Best Mid-Cap Materials Stocks to Buy Now.

In 2025, the U.S. construction and materials sector entered an uncertain era. The industry is currently focused on two areas: changes in domestic immigration policy and new developments in international trade that could affect the cost of building materials. As such, it should come as no surprise to anyone that 2025 is shaping up to be a crucial year for the sector, given that the current cycle’s building activity is slowing down.

However, there are still advancements that encourage market growth and competition. Cognitive Market Research projects that the global materials market, which encompasses metals, polymers, ceramics, and composites, will increase at a compound annual growth rate (CAGR) of 5.2% to reach $1.9 trillion by 2026.

To that end, technological advancements appear as a major driver of the industry . In recent times, engineers and builders employ 4D and 5D simulations to solve workflow problems brought on by worker shortages and scheduling conflicts. The transition of the materials sector to sector 4.0 and the establishment of a “smart factory” also seems to be well advanced.

That being said, let us now take a look at the list of the 12 best mid-cap materials stocks to buy now.
