Refiners are different from oil drillers — they profit from the spread between cheap crude and expensive finished fuel, and right now that spread is historically wide because global refining capacity has shrunk while demand hasn't. The article notes this

Verdict: Wait for the washout

The refining-spread thesis is real: MPC generated $4.8B in free cash flow last fiscal year (96th percentile among Energy peers), its ROE of 23.4% ranks 83rd percentile, and per the Bloomberg piece, US refiners are seeing billions in profits from a global fuel crunch driven by years of international refinery closures plus war-driven supply disruptions. But the trade architecture isn't ready — all three names trade above their Bollinger midlines with RSI in the low-to-mid 60s, and the strategy demands an oversold washout with RSI below 45 before arming a crossover entry. The backtest evidence is also thin: the 19.0% return comes from a single MPC trade over 60 months, PSX and VLO produced zero triggers in the evaluated window, and no robust parameter setup was established after the sensitivity analysis exceeded its time budget. Most concerning, VLO's gross margin of just 4.4% (8th percentile) and MPC's debt-to-equity doubling to 1.76 from 0.83 at year-end 2019 mean a crack-spread compression could quickly pressure the basket. **Conviction breakdown:** Thesis support is moderate — the structural narrative and MPC's cash generation are genuine, but all three names posted negative revenue growth. Trade readiness is low — RSI is 16 to 21 points above the entry threshold for each ticker. Risk quality is mixed — the 2.4% stop is tight for stocks with 27–32% annualized volatility and negative skew. Backtest evidence is weak — one trade across one ticker is not a sample. Fundamentals trend is neutral — ROE is strong but margins are thin and leverage is rising at MPC.

Trade now: Refiners are running hot — entry needs a pullback

All three refiners are trading near the top of their recent ranges, and the strategy is **not in its entry zone today**. MPC closed at $314.82, PSX at $210.82, and VLO at $311.15 — each above its 20-day Bollinger Band midline. The entry architecture demands a specific sequence: price must first touch or dip below the lower Bollinger Band (signaling an oversold washout), RSI (14) must fall below 45, and then price must cross back above the Bollinger midline with ADX above 20 to confirm trend strength. Right now the opposite is happening — these stocks are strong, not washed out. On the distance-to-trigger read: MPC's RSI is 61.3 and needs to drop below 45 (16.3 points away); PSX is at 65.1 (20.1 points away); VLO is at 66.1 (21.1 points away). The ADX trend filter is comfortably met across all three — MPC at 35.0, PSX at 67.5, VLO at 59.8 — so once momentum cools, the trend-strength prerequisite won't be a bottleneck. The lower Bollinger Band sits at $312.29 for MPC, meaning a drop of just $2.53 would start building the oversold condition, but RSI is the true gating factor at current readings. **What 'wait' means concretely:** Do nothing today. Set price alerts on each ticker at the lower Bollinger Band level (MPC ~$312, PSX ~$208, VLO ~$305) as an early warning, but recognize the real signal requires RSI to compress from the low-60s into the low-40s — a meaningful momentum cooling. Once triggered, the strategy's hard stop is at 2.4% downside from entry and the fixed take-profit targets 4.8% upside, producing an effective reward-to-risk ratio of roughly 2:1. The 60-month backtest on MPC produced a 19.0% return with a 5.1% maximum drawdown on a single completed trade, though with only one trigger across the evaluation window, the sample is thin. No robust parameter setup was established, as the sensitivity analysis exceeded its time budget without returning a recommendation. On the exit side, if a position is taken, the 21-day EMA serves as a trailing signal exit after a 90-bar holding period — currently $305.70 for MPC, $204.58 for PSX, and $299.21 for VLO. The shorter-term guardrails (2.4% stop, 4.8% target) would likely fire well before the EMA exit becomes relevant.

The crack-spread tailwind has real cash-flow backing

The idea argues that the refiner bull case rests on durable structural factors — years of international refinery closures and war-driven supply disruptions — rather than a fleeting quarter of wide crack spreads. The Bloomberg piece from July 30, 2026 corroborates this narrative, reporting that US refiners are seeing “billions in profits from global fuel crunch.” MPC's fundamentals offer hard evidence that the thesis is translating into actual cash: the company generated $4.77 billion in free cash flow in its latest fiscal year, placing it in the…
