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 June 29, 2026, spot at $68.93, ATM IV 173.70%, IV rank 34.24%, expected move 49.80%. 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 18-day expiry.
Why this strangle structure on STN specifically: STN IV at 173.70% 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 49.80% (roughly $34.33 on the underlying). The 18-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 $68.93 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 $68.93, the first option leg uses a $72.38 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 18-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 | $72.38 | N/A |
| Buy 1 | Put | $65.48 | N/A |

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

- None on modeled curve
- Risk / Reward Ratio

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 $34.60 on the downside to $103.26 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 34.24% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on STN should anchor more to the directional view and the expected-move geometry. 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 $68.93, 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 173.70%), 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 49.80%; 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 173.70% with IV rank near 34.24%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.
