I wanted to understand whether the market is actually buying our integration narrative—or whether repeating it is meaningfully changing how investors who trade PSX perceive the company.
To test this, I analyzed daily share price correlations between PSX and a set of peers—MPC, VLO, DINO, and PBF, with XOM and CVX included as examples of truly integrated energy companies—across 5-, 3-, 2-, and 1-year periods.
The results are clear and consistent: PSX trades most like Valero, and that relationship is stable across every time horizon. Only in the most recent one-year period does PSX trade marginally more like MPC, but even then, its correlation with refining peers increased, not decreased. In contrast, correlations with XOM and CVX remain materially lower and largely unchanged over time.
The market is telling us something straightforward: PSX is viewed as a refiner, and that perception is not evolving.
Rather than fighting that reality, we should consider embracing it—making the hard choices required to present PSX as a pure-play refining and marketing company, one that investors can clearly benchmark against peers and value accordingly.
