How are SUN straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the SUN straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 23.00%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$388.80 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a SUN straddle?

The breakeven for the SUN straddle priced on this page is roughly $66.00 and $74.00 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 SUN market-implied 1-standard-deviation expected move is approximately 6.59%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.

How does current SUN implied volatility affect this straddle?

SUN ATM IV is at 23.00% with IV rank near 3.17%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.

SUN Straddle Strategy

SUN (Sunoco LP), in the Energy sector, (Oil & Gas Refining & Marketing industry), listed on NYSE.

Sunoco LP, together with its subsidiaries, distributes and retails motor fuels in the United States. It operates in two segments, Fuel Distribution and Marketing, and All Other. The Fuel Distribution and Marketing segment purchases motor fuel from independent refiners and oil companies and supplies it to independently operated dealer stations, distributors and other consumer of motor fuel, and partnership operated stations, as well as to commission agent locations. The All Other segment operates retail stores that offer motor fuel, merchandise, foodservice, and other services that include credit card processing, car washes, lottery, automated teller machines, money orders, prepaid phone cards, and wireless services.

SUN (Sunoco LP) trades in the Energy sector, specifically Oil & Gas Refining & Marketing, with a market capitalization of approximately $9.56B, a trailing P/E of 11.47, a beta of 0.47 versus the broader market, a 52-week range of 47.98-70, average daily share volume of 526K, a public-listing history dating back to 2012, approximately 3K full-time employees. These structural characteristics shape how SUN stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

A beta of 0.47 indicates SUN has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. The trailing P/E of 11.47 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price. SUN pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

What is a straddle on SUN?

A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.

Current SUN snapshot

As of May 15, 2026, spot at $71.18, ATM IV 23.00%, IV rank 3.17%, expected move 6.59%. The straddle on SUN 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 34-day expiry.

Why this straddle structure on SUN specifically: SUN IV at 23.00% is on the cheap side of its 1-year range, which favors premium-buying structures like a SUN straddle, with a market-implied 1-standard-deviation move of approximately 6.59% (roughly $4.69 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SUN expiries trade a higher absolute premium for lower per-day decay. Position sizing on SUN should anchor to the underlying notional of $71.18 per share and to the trader's directional view on SUN stock.

SUN straddle setup

The SUN straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SUN near $71.18, the first option leg uses a $70.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SUN chain at a 34-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 SUN shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$70.00	$2.58
Buy 1	Put	$70.00	$1.43

When traders use straddle on SUN

Straddles on SUN are pure-volatility plays that profit from large moves in either direction; traders typically buy SUN straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

SUN thesis for this straddle

The market-implied 1-standard-deviation range for SUN extends from approximately $66.49 on the downside to $75.87 on the upside. A SUN long straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. Current SUN IV rank near 3.17% sits in the lower third of its 1-year distribution, where IV often re-expands toward the mean; this favors premium-buying structures and disadvantages premium-selling structures on SUN at 23.00%. As a Energy name, SUN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SUN-specific events.

SUN straddle positions are structurally neutral / high-volatility (long premium); 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. SUN positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SUN alongside the broader basket even when SUN-specific fundamentals are unchanged. Always rebuild the position from current SUN chain quotes before placing a trade.
