What is a strangle on SWX?
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.
SWX snapshot
As of August 14, 2026, spot at $92.47, ATM IV 384.50%, IV rank 76.71%, expected move 110.23%. The strangle on SWX below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this strangle structure on SWX specifically: SWX IV at 384.50% is rich versus its 1-year range, which makes a premium-buying SWX strangle relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 110.23% (roughly $101.93 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SWX expiries trade a higher absolute premium for lower per-day decay. Position sizing on SWX should anchor to the underlying notional of $92.47 per share and to the trader's directional view on SWX stock.
SWX strangle setup
The SWX 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 SWX at $92.47 on that close, the first option leg uses a $97.09 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SWX chain at a 35-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 SWX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $97.09 | N/A |
| Buy 1 | Put | $87.85 | N/A |
SWX strangle risk and reward
- Net Premium / Debit

- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)

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 SWX
Strangles on SWX 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 SWX chain.
SWX thesis for this strangle
The market-implied 1-standard-deviation range for SWX extends from approximately $-9.46 on the downside to $194.40 on the upside. A SWX 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 SWX IV rank near 76.71% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on SWX at 384.50%. As a Utilities name, SWX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SWX-specific events.
SWX 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. SWX positions also carry Utilities sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SWX alongside the broader basket even when SWX-specific fundamentals are unchanged. Always rebuild the position from current SWX chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on SWX?
- A strangle on SWX is the strangle strategy applied to SWX (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 SWX stock at $92.47 on the most recent close, the strikes shown on this page are snapped to the nearest listed SWX chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are SWX 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 SWX strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 384.50%), 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 SWX strangle?
- The breakeven for the SWX strangle priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The SWX market-implied 1-standard-deviation expected move in the same options snapshot is approximately 110.23%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on SWX?
- Strangles on SWX 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 SWX chain.
- How does current SWX implied volatility affect this strangle?
- SWX ATM IV is at 384.50% with IV rank near 76.71%, which is elevated relative to its 1-year range. Premium-selling structures (covered call, cash-secured put, iron condor) generally look more attractive when IV rank is high; premium-buying structures (long call, long put, debit spreads) are more expensive in that regime.
