Marathon Petroleum Slumps 2.8%—Is the Downgrade the Tip of the Iceberg?

• Wolfe Research downgrades MPC to 'Peer Perform,' sparking a $5.11 selloff to $174.75
• Valero (VLO) mirrors decline, down 2.97% amid sector-wide refining margin concerns
• Institutional selling and mixed analyst targets create tension at $165 support battleground

Marathon Petroleum’s Monday selloff carved a sharp $5.11 drop from its open, slicing 2.84% from its price to $174.75—the lowest since late June. The 52W range ($115.10–$183.31) frames this move as a pullback from recent highs, with traders eyeing $165 support as the next critical test. Volume at 933,698 shares lagged its 2.7M average, suggesting cautious participation ahead of key sector dynamics.

Downgrade Sparks Profit-Taking Amid Mixed Analyst Optimism
The 2.84% plunge directly traces to Wolfe Research’s downgrade from 'Outperform' to 'Peer Perform,' stripping MPC of one of its final bullish ratings. Despite this, 13 analysts retain buy/hold ratings with a $184.38 average target, suggesting the sell-off may overreact to near-term volatility. First-quarter results added ambiguity: MPC beat EPS estimates by $0.16 but reported a net loss of $0.24 and year-over-year revenue contraction. Institutional selling—such as New York State Retirement’s 7.9% stake reduction—fueled short-term pressure, while the downgrade amplified profit-taking ahead of Q2 earnings.

Refining Sector Stumbles as Valero Mirrors MPC’s Decline
MPC’s 2.84% drop aligns with sector-wide refining margin concerns, as Valero (VLO) tumbled 2.97% to $55.78—a key support level for the sector. Both stocks face challenges in refining margins and global crude flows, though MPC’s stronger 200-day moving average (151.69 vs. VLO’s 129.30) suggests deeper technical support. Venezuelan tariff dynamics and diesel demand growth—highlighted in recent sector reports—remain unresolved, creating crosscurrents for mid-cap refiners like MPC. The sector’s reliance on these macro factors keeps volatility elevated.

Target MPC20250718P170 Put and MPC20250718C175 Call for Near-Term Volatility
Technical Indicators:
• 200-day SMA: $151.69 (support anchor)
• RSI: 69.64 (neutral-bullish)
• Bollinger Bands: Lower at $159.43

Bulls should focus on $172.72 (30DMA) as a near-term hurdle, while bears target $165.00—the 2024 low. Short-side traders can exploit the MPC20250718P170 Put (strike $170), which offers 207% leverage and high turnover (2,926 contracts). Its delta of -0.20 and gamma of 0.037 amplify downside gains, with theta decay (-0.033) favoring time-sensitive bets. For bullish reversals, the MPC20250718C175 Call (strike $175) delivers 66.7% leverage and a delta of 0.58, ideal for rallies above $177.50.

Payoff Example: A 5% downside to $165.71 yields $4.29 intrinsic value for the $170 put, while the $175 call retains $0.25 if MPC rebounds to $177.50.

Action: Short the MPC20250718P170 into $165.00 support tests—target $160 by week’s end. Bulls: Accumulate MPC20250718C175 if $172.72 holds.

Backtest Marathon Petroleum Stock Performance
The backtest of Morgan Stanley Capital International (MPC) after an intraday percentage change of less than -3% shows favorable performance metrics. The 3-Day win rate is 52.81%, the 10-Day win rate is 53.51%, and the 30-Day win rate is 54.04%. Although the maximum return during the backtest period is only 0.34% on day 29, the overall trend suggests that MPC tends to recover modestly following a significant intraday plunge.

Hold the Line at $165 or Face a Sector Sell-Off?
Marathon Petroleum’s fate hinges on whether $165 support holds amid refining margin uncertainties. The $170 put’s liquidity and leverage make it optimal for short-side plays, while $175 calls offer asymmetric rewards for rebounds. Watch Valero’s $55.78 level—a sector breakdown could drag MPC deeper. Traders should focus on July 18 expiration and $165 support; failure risks a slide toward $150. Stay nimble: This is a trap for bulls and a buying opportunity at $160.
