Exxon, Chevron set for $26B quarter; refiners hold up in Iran war trade
Marathon Petroleum and Valero Energy jumped about 3.8% each in late-morning trading on Monday. Exxon Mobil added 3.4%. Chevron was up 2.2%. Brent crude was up more than 4%, above $79 a barrel, after President Donald Trump said the U.S. is bringing back its naval blockade of Iran. The split in refiners and oil majors points to stronger fuel margins, not just the crude rally, as the key driver for earnings.
