How are ISRG straddle max profit and max loss calculated?

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the ISRG straddle 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 -$2,669.37 per contract. Live intraday quotes will differ as the chain moves through the trading session.

ISRG snapshot

As of August 14, 2026, spot at $396.28, ATM IV 30.63%, IV rank 26.09%, expected move 8.78%. The straddle 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 straddle 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 straddle, 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 straddle setup

The ISRG straddle 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 $395.00 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	$395.00	$15.40
Buy 1	Put	$395.00	$12.00

When traders use straddle on ISRG

Straddles on ISRG are pure-volatility plays that profit from large moves in either direction; traders typically buy ISRG straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.

ISRG thesis for this straddle

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 straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. 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 straddle positions are structurally neutral / high-volatility (long premium); 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.
