What is a strangle on STN?
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 STN snapshot
As of May 15, 2026, spot at $77.02, ATM IV 34.90%, IV rank 4.68%, expected move 10.01%. The strangle on STN 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 STN specifically: STN IV at 34.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a STN strangle, with a market-implied 1-standard-deviation move of approximately 10.01% (roughly $7.71 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 STN expiries trade a higher absolute premium for lower per-day decay. Position sizing on STN should anchor to the underlying notional of $77.02 per share and to the trader's directional view on STN stock.
STN strangle setup
The STN 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 STN near $77.02, the first option leg uses a $80.87 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STN 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 STN shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $80.87 | N/A |
| Buy 1 | Put | $73.17 | N/A |
STN strangle risk and reward
- Net Premium / Debit
- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)
- Unbounded
- Breakeven(s)
- 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 STN
Strangles on STN 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 STN chain.
STN thesis for this strangle
The market-implied 1-standard-deviation range for STN extends from approximately $69.31 on the downside to $84.73 on the upside. A STN 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 STN IV rank near 4.68% 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 STN at 34.90%. As a Industrials name, STN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STN-specific events.
STN 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. STN positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STN alongside the broader basket even when STN-specific fundamentals are unchanged. Always rebuild the position from current STN chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on STN?
- A strangle on STN is the strangle strategy applied to STN (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 STN stock trading near $77.02, the strikes shown on this page are snapped to the nearest listed STN chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are STN 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 STN strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 34.90%), 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 STN strangle?
- The breakeven for the STN 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 STN market-implied 1-standard-deviation expected move is approximately 10.01%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on STN?
- Strangles on STN 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 STN chain.
- How does current STN implied volatility affect this strangle?
- STN ATM IV is at 34.90% with IV rank near 4.68%, 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.
