Valero, Marathon Petroleum, HF Sinclair and Phillips 66 have gained for six consecutive weeks as diesel crack spreads hit an all-time record.
A $1,000 investment in Marathon Petroleum (MPC) made in September 2016 would be worth $9,673.54 as of September 18, 2026, representing an 867.35% gain. This significantly outperformed the S&P 500's 257.04% return over the same period. Analysts maintain an Outperform rating, citing the company's scale, integrated refining system, midstream operations through MPLX, and favorable refining margins.
Valero Energy has risen more than 200% in two years, outpacing every Magnificent Seven stock, including Nvidia. Almost the entire move came in 2026, driven by a collapse in global refining capacity rather than by the oil price. The average analyst price target now sits 31% below the stock.
