Executive Summary

Three major passive institutional investors — Morgan Stanley, Wells Fargo, and Schwab — fully exited their positions in Marathon Oil Corp (MRO) during Q4 2024, collectively selling $422.7 million worth of shares. This complete divestment by mega-passive funds suggests a coordinated reduction in exposure, likely due to sector rebalancing or risk-off positioning rather than active bearish sentiment.
