Since 2016, ConocoPhillips (COP) has been the best performing Major Oil stock as well as one of the best stocks in the entire energy sector on its proven capital allocation strategy and strong execution, JPMorgan analyst Arun Jayaram tells investors in a research note. He sees similar attributes at Marathon Oil (MRO). The company's organic break-even after dividend coverage of $45 per barrel "stacks up solidly" against ConocoPhillips given its low double digit oil growth profile, adds the analyst. He believes Marathon Oil have the potential to perform well on a relative basis as the market continues to value free cash flow generation and cash return over growth at conservative oil prices. Jayaram reiterates an Overweight rating on the name.
