U.S. Gasoline Waiver Challenges $22 Billion Valuation Edge for Refiners
The premature conclusion of U.S. summer-gasoline regulations puts about $22 billion in valuation premium at risk for three leading refiners. Shares of Valero Energy Corp., Marathon Petroleum Corp. and Phillips 66 remain above consensus analyst price targets. The increased supply flexibility may relieve prices at the pump, but could also trim gasoline scarcity margins.

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%.
