Commenting on reports that the White House will issue an executive order shifting the point of obligation, the burden of compliance with the EPA Renewable Fuel Standard ethanol blending requirement, away from the refiners and onto the marketers/retailers, Evercore ISI analyst Thomas Cape continues to like the refiners with the larger RIN exposures, such as Valero (VLO), Hollyfrontier (HFC) and PBF Energy (PBF). The analyst's least favorites are the retail/convenience store names who would bear the responsibility of compliance with the RFS post the flip, including Murphy USA (MUSA) and Casey Retail (CASY).
