This robust rally comes as refining margins show significant improvement compared to peers; for instance, previous data from Phillips 66 indicated stable cash flow growth, enhancing the sector's appeal to dividend-seeking investors. Per market data, the continued commitment of these firms to share buybacks and consistent dividend payments has helped the sector outperform broader energy indices in recent months.

Traders are currently monitoring any potential updates from international energy meetings or US inventory reports as upcoming catalysts, particularly following the conclusion of a series of influential macroeconomic data points in early July.
