Vulcan Materials Company (VMC) stock: Winston Score, insiders and Congress trades

Vulcan Materials is the largest producer of construction aggregates in the United States. Aggregates are crushed stone, sand, and gravel — the basic building blocks used in roads, bridges, airports, and buildings. Its customers include construction companies, government agencies, and contractors working on both public infrastructure and private development projects. Vulcan makes money by mining and selling these materials by the ton, primarily across the eastern, southern, and western United States. Because quarries are expensive to open and heavily regulated, it is very difficult for competitors to build new ones near existing customers — this gives Vulcan a durable local pricing advantage in most of its markets. The key growth driver is increased federal infrastructure spending through programs like the Infrastructure Investment and Jobs Act, which is expected to boost demand for aggregates over the next several years; the main risk is that a slowdown in construction activity, particularly in housing and commercial real estate, could reduce volumes and pressure margins.
