Hedge funds favor GATX Corporation (NYSE:GATX) because of its exceptionally stable operations. As of early 2026, GATX reported a 99% utilization rate for its North American rail fleet. Institutional analysts note that strong supply dynamics in the railcar market have allowed GATX to renew leases at significantly higher rates, driving organic revenue growth. A primary driver for hedge fund interest in the stock is the successful integration of the Wells Fargo railcar fleet acquisition. The addition of these assets has contributed to GATX’s 2026 guidance, which projects a 10% increase in EPS, estimated at $9.50–$10.10. By increasing its fleet size, GATX has lowered its per-unit maintenance costs as well.
