Bullish Case: MPC’s $373.31 price sits near the Helium/market future-density peak around $370–$380, while call volume exceeds put volume by 17%, bullish risk is 45% greater, and earnings-beat odds are 76%. The historical-return surface favors modest positive outcomes. A 2.71% Helium price bias and recent 5.2% weekly gain support continued strength, though the zero historical forecast correlation materially limits confidence.

Bearish Case: The rally is already extended: MPC is up 40.1% in 90 days, leaving valuation and mean-reversion risk despite a 1.8 price-to-book ratio. El Paso emissions investigations create company-specific regulatory and outage risk, while political pressure to reduce gasoline prices could compress refining economics. The SPY surface shows pronounced downside-skewed volatility, so a broader risk-off move could amplify MPC’s downside even though central volatility is stable.

Potential Outcomes:

1. +3–8%: 42%—earnings beat and firm refining margins; falsified by weak guidance or sustained margin deterioration.
2. −3% to +3%: 28%—density remains near $370–$380 and IV stays near 44–45%.
3. −8–15%: 18%—El Paso enforcement, outage, oil shock, or SPY selloff.
4. +8–15%: 12%—strong results plus upward guidance.
