Marathon Petroleum (MPC) and Valero Energy (VLO) Have Exploded in 2026. But Barron’s Sees More Upside

Marathon Petroleum (MPC) and Valero Energy (VLO) have more than doubled in value in 2026 due to strong refining margins. Both companies reported combined profits of $8.8 billion in Q2 2026, exceeding expectations. Barron's suggests further upside potential, citing persistent global refining capacity constraints and strong shareholder returns. However, risks include potential normalization of margins and significant stock rallies (111% for VLO, 118% for MPC).
