What is the breakeven for a MPC long put?

The breakeven for the MPC long put priced on this page is roughly $249.50 at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current MPC market-implied 1-standard-deviation expected move is approximately 10.49%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current MPC implied volatility affect this long put?

MPC Long Put Strategy

MPC (Marathon Petroleum Corporation), in the Energy sector, (Oil & Gas Refining & Marketing industry), listed on NYSE.

Marathon Petroleum Corporation (MPC) functions as a prominent integrated energy enterprise, primarily concentrating its downstream operations across the United States. Its business is bifurcated into two main divisions: Refining & Marketing, and Midstream. The Refining & Marketing segment is responsible for processing crude oil and various other raw materials at its refineries, strategically located in the U.S. Gulf Coast, Mid-Continent, and West Coast regions. This division also acquires refined petroleum products and ethanol for subsequent distribution. Key outputs from this segment encompass a diverse array of transportation fuels, including different gasoline blends, heavy fuel oil, and asphalt.

MPC (Marathon Petroleum Corporation) trades in the Energy sector, specifically Oil & Gas Refining & Marketing, with a market capitalization of approximately $74.17B, a trailing P/E of 16.18, a beta of 0.52 versus the broader market, a 52-week range of 158-272.46, average daily share volume of 2.4M, a public-listing history dating back to 2011, approximately 18K full-time employees. These structural characteristics shape how MPC stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.52 indicates MPC has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. MPC pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a long put on MPC?

A long put buys downside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes below the strike minus premium at expiration.

Current MPC snapshot

As of June 30, 2026, spot at $255.28, ATM IV 36.60%, IV rank 46.84%, expected move 10.49%. The long put on MPC below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.

Why this long put structure on MPC specifically: MPC IV at 36.60% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 10.49% (roughly $26.79 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated MPC expiries trade a higher absolute premium for lower per-day decay. Position sizing on MPC should anchor to the underlying notional of $255.28 per share and to the trader's directional view on MPC stock.

MPC long put setup

The MPC long put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With MPC near $255.28, the first option leg uses a $260.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed MPC chain at a 17-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 MPC shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)

When traders use long put on MPC

Long puts on MPC hedge an existing long MPC stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying MPC exposure being hedged.

MPC thesis for this long put

The market-implied 1-standard-deviation range for MPC extends from approximately $228.49 on the downside to $282.07 on the upside. A MPC long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long MPC position with one put per 100 shares held. Current MPC IV rank near 46.84% is mid-range against its 1-year distribution, so the IV signal is neutral; the long put thesis on MPC should anchor more to the directional view and the expected-move geometry. As a Energy name, MPC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to MPC-specific events.

MPC long put positions are structurally bearish; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. MPC positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move MPC alongside the broader basket even when MPC-specific fundamentals are unchanged. Long-premium structures like a long put on MPC are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current MPC chain quotes before placing a trade.
