Refiners Rally as Strong Margins Drive Downstream Outperformance in Oil Sector

Beneath the surface of the oil and gas sector’s solid one-year aggregate return, a sharp divergence is taking shape. While upstream producers contend with lower crude prices that pressure earnings, downstream refiners are capitalizing on strong refining margins. The result is a trio of stocks delivering exceptional quarterly earnings growth, rare technical strength, and forward valuations that remain well within reason.

Marathon Petroleum

Marathon Petroleum (NYSE:MPC) illustrates the downstream advantage most vividly. Its latest quarterly EPS surged almost eightfold compared to the same period last year, and the stock carries the highest relative strength reading in the group outside of Valero. The technical picture is equally noteworthy, with a perfect 10 out of 10 rating, yet the forward earnings multiple is far from stretched.

  • EPS growth (last quarter vs. prior year): +787.5%
  • Relative strength percentile: 94.7
  • Forward P/E: 13.0
  • Operating margin growth (TTM vs. prior year): +56.7%
  • Technical rating: 10 / 10

The numbers suggest that the market is rewarding Marathon for a cycle where crack spreads are providing a strong tailwind. The combination of a mid-teens forward earnings multiple and top-decile momentum implies that valuation has not yet caught up with the earnings trajectory. For investors looking for a refiner with both momentum and a reasonable entry point, Marathon presents a rare blend.

Valero Energy

Valero Energy (NYSE:VLO) also reflects the strength in downstream margins. Its quarterly EPS jumped 374% year-over-year, and the stock’s relative strength of 96.3 is the highest among the three refiners. Operating margin growth surged even more dramatically, showing how quickly profitability has improved in the current environment.

  • EPS growth (last quarter vs. prior year): +374%
  • Relative strength percentile: 96.3
  • Forward P/E: 14.4
  • Operating margin growth (TTM vs. prior year): +159%
  • Technical rating: 10 / 10

Valero’s numbers point to a business that not only benefits from wide refining margins but also operates efficiently enough to convert them into outsized earnings. The forward P/E of roughly 14.4 is reasonable for a company with this rate of improvement, and the technical score confirms that the market’s favor is backed by sustained price momentum. Investors are effectively paying a moderate multiple for a business in the midst of a profitability boom.

Phillips 66

Phillips 66 (NYSE:PSX) rounds out the downstream trio with the lowest forward earnings multiple of the group. Its EPS growth of 154% is still impressive by absolute standards, and the stock’s relative strength of 92.7 places it among the strongest performers in the market. The operating margin improvement was the most dramatic of the three, expanding by more than 300% on a trailing basis.

  • EPS growth (last quarter vs. prior year): +154%
  • Relative strength percentile: 92.7
  • Forward P/E: 11.7
  • Operating margin growth (TTM vs. prior year): +326%
  • Technical rating: 10 / 10

Phillips 66 offers a slightly different risk profile. The forward P/E of 11.7 is the most attractive entry point of the group, but the free cash flow conversion has been weak in the latest period, which is a point of caution. The operating margin expansion, however, signals that the underlying business is generating significantly more profit per dollar of revenue. The low forward multiple may reflect some skepticism about sustainability, but the momentum and margin data argue that the current cycle is delivering real earnings strength.

These three refiners form a coherent subset within the broader Oil and Gas Stocks universe. While the sector as a whole has posted strong one-year performance, the downstream players are distinctly pulling ahead on earnings momentum and technical strength, all while trading at forward multiples that leave room for further upside if margins persist.
