How are ISRG 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 ISRG strangle priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 30.63%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$1,105.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a ISRG strangle?

The breakeven for the ISRG strangle priced on this page is roughly $363.95 and $426.05 at expiration, derived from the August 14, 2026 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.

ISRG snapshot

As of August 14, 2026, spot at $396.28, ATM IV 30.63%, IV rank 26.09%, expected move 8.78%. The strangle on ISRG below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 28-day expiry.

Why this strangle structure on ISRG specifically: ISRG IV at 30.63% is on the cheap side of its 1-year range, which favors premium-buying structures like a ISRG strangle, with a market-implied 1-standard-deviation move of approximately 8.78% (roughly $34.80 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ISRG expiries trade a higher absolute premium for lower per-day decay. Position sizing on ISRG should anchor to the underlying notional of $396.28 per share and to the trader's directional view on ISRG stock.

ISRG strangle setup

The ISRG strangle below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ISRG at $396.28 on that close, the first option leg uses a $415.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ISRG chain at a 28-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 ISRG shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$415.00	$6.40
Buy 1	Put	$375.00	$4.65

When traders use strangle on ISRG

Strangles on ISRG 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 ISRG chain.

ISRG thesis for this strangle

The market-implied 1-standard-deviation range for ISRG extends from approximately $361.48 on the downside to $431.08 on the upside. A ISRG 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 ISRG IV rank near 26.09% 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 ISRG at 30.63%. As a Healthcare name, ISRG options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ISRG-specific events.

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