YTD as of 2026-09-04 · source: Yahoo Finance
Martin Marietta Materials, Inc. operates across U.S. aggregates-led materials. After +21.3% in 2025, it corrected -17% in 2026. The supply side (avg +32.8%) has moved harder than the stock (-17%). That is the classic bottleneck pattern: supplier volume leverage is being priced before this layer's own margin. Among connected nodes the furthest ahead is Caterpillar (+42.9%) and the furthest behind is Union Pacific Corporation (+27.1%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. It spends on quarry equipment and rail logistics and expands its supply base through aggregates and specialty-materials acquisitions.
