What is a strangle on SOBO?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current SOBO snapshot
As of May 15, 2026, spot at $37.22, ATM IV 30.20%, IV rank 20.88%, expected move 8.66%. The strangle on SOBO 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 strangle structure on SOBO specifically: SOBO IV at 30.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a SOBO strangle, with a market-implied 1-standard-deviation move of approximately 8.66% (roughly $3.22 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 SOBO expiries trade a higher absolute premium for lower per-day decay. Position sizing on SOBO should anchor to the underlying notional of $37.22 per share and to the trader's directional view on SOBO stock.
SOBO strangle setup
The SOBO strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SOBO near $37.22, the first option leg uses a $39.08 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SOBO 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 SOBO shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $39.08 | N/A |
| Buy 1 | Put | $35.36 | N/A |
SOBO strangle risk and reward
- Net Premium / Debit
- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- Unbounded

- None on modeled curve
- Risk / Reward Ratio
- N/A
Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit.

When traders use strangle on SOBO
Strangles on SOBO are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the SOBO chain.
SOBO thesis for this strangle
The market-implied 1-standard-deviation range for SOBO extends from approximately $34.00 on the downside to $40.44 on the upside. A SOBO long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current SOBO IV rank near 20.88% 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 SOBO at 30.20%. As a Energy name, SOBO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SOBO-specific events.
SOBO strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. SOBO positions also carry Energy sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SOBO alongside the broader basket even when SOBO-specific fundamentals are unchanged. Always rebuild the position from current SOBO chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on SOBO?
- A strangle on SOBO is the strangle strategy applied to SOBO (stock). The strategy is structurally neutral / high-volatility (long premium, OTM): A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money. With SOBO stock trading near $37.22, the strikes shown on this page are snapped to the nearest listed SOBO chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are SOBO strangle max profit and max loss calculated?
- Upside max profit is unbounded; downside max profit is bounded at the put strike minus the combined debit (reached at zero). Max loss equals the combined debit times 100 (reached anywhere between the two OTM strikes). Two breakevens at call-strike plus debit and put-strike minus debit. For the SOBO strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 30.20%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a SOBO strangle?
- The breakeven for the SOBO strangle priced on this page is no defined breakeven on the modeled curve 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 SOBO market-implied 1-standard-deviation expected move is approximately 8.66%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on SOBO?
- Strangles on SOBO are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the SOBO chain.
- How does current SOBO implied volatility affect this strangle?
- SOBO ATM IV is at 30.20% with IV rank near 20.88%, 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.
