How are STRL 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 STRL strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 74.70%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$11,025.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a STRL strangle?

What is a strangle on STRL?

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 STRL snapshot

As of May 15, 2026, spot at $853.71, ATM IV 74.70%, IV rank 64.12%, expected move 21.42%. The strangle on STRL 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 STRL specifically: STRL IV at 74.70% 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 21.42% (roughly $182.83 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 STRL expiries trade a higher absolute premium for lower per-day decay. Position sizing on STRL should anchor to the underlying notional of $853.71 per share and to the trader's directional view on STRL stock.

STRL strangle setup

The STRL 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 STRL near $853.71, the first option leg uses a $900.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STRL 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 STRL shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$900.00	$56.55
Buy 1	Put	$810.00	$53.70

When traders use strangle on STRL

Strangles on STRL 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 STRL chain.

STRL thesis for this strangle

The market-implied 1-standard-deviation range for STRL extends from approximately $670.88 on the downside to $1,036.54 on the upside. A STRL 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 STRL IV rank near 64.12% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on STRL should anchor more to the directional view and the expected-move geometry. As a Industrials name, STRL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STRL-specific events.

STRL 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. STRL positions also carry Industrials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STRL alongside the broader basket even when STRL-specific fundamentals are unchanged. Always rebuild the position from current STRL chain quotes before placing a trade.
