What is a straddle on INSM?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the strike at expiration.
Current INSM snapshot
As of May 15, 2026, spot at $109.73, ATM IV 48.90%, IV rank 27.06%, expected move 14.02%. The straddle on INSM 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 straddle structure on INSM specifically: INSM IV at 48.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a INSM straddle, with a market-implied 1-standard-deviation move of approximately 14.02% (roughly $15.38 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 INSM expiries trade a higher absolute premium for lower per-day decay. Position sizing on INSM should anchor to the underlying notional of $109.73 per share and to the trader's directional view on INSM stock.
INSM straddle setup
The INSM straddle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With INSM near $109.73, the first option leg uses a $110.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed INSM 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 INSM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $110.00 | $6.65 |
| Buy 1 | Put | $110.00 | $6.50 |

When traders use straddle on INSM
Straddles on INSM are pure-volatility plays that profit from large moves in either direction; traders typically buy INSM straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
INSM thesis for this straddle
The market-implied 1-standard-deviation range for INSM extends from approximately $94.35 on the downside to $125.11 on the upside. A INSM 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 INSM IV rank near 27.06% 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 INSM at 48.90%. As a Healthcare name, INSM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to INSM-specific events.
INSM 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. INSM positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move INSM alongside the broader basket even when INSM-specific fundamentals are unchanged. Always rebuild the position from current INSM chain quotes before placing a trade.
