On August 4, Marathon Petroleum declined 3.71% overnight, trading at $295.63/share, with turnover of 201,400 USD.

The decline was driven by falling crude oil prices amid weakening global demand expectations, which intensified pressure on refining margins. The broader refining sector saw significant losses, with PBF Energy falling 6.83%, HF Sinclair down 4.11%, Delek US Holdings declining 3.6%, Valero dropping 2.98%, and Phillips 66 losing 2.93%. Market participants noted that near-term demand signals have deteriorated, weighing heavily on crack spread expectations and refiner profitability outlooks.

The sell-off comes ahead of Marathon Petroleum's quarterly earnings report scheduled for pre-market on August 4, with consensus EPS estimates at $14.52. Investors appear cautious about whether the recent price recovery trend can be sustained amid the softening demand environment.
