What is a straddle on SENS?
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 SENS snapshot
As of May 15, 2026, spot at $5.75, ATM IV 84.50%, IV rank 19.46%, expected move 24.23%. The straddle on SENS 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 SENS specifically: SENS IV at 84.50% is on the cheap side of its 1-year range, which favors premium-buying structures like a SENS straddle, with a market-implied 1-standard-deviation move of approximately 24.23% (roughly $1.39 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 SENS expiries trade a higher absolute premium for lower per-day decay. Position sizing on SENS should anchor to the underlying notional of $5.75 per share and to the trader's directional view on SENS stock.
SENS straddle setup
The SENS 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 SENS near $5.75, the first option leg uses a $5.75 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SENS 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 SENS shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |

When traders use straddle on SENS
Straddles on SENS are pure-volatility plays that profit from large moves in either direction; traders typically buy SENS straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
SENS thesis for this straddle
The market-implied 1-standard-deviation range for SENS extends from approximately $4.36 on the downside to $7.14 on the upside. A SENS 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 SENS IV rank near 19.46% 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 SENS at 84.50%. As a Healthcare name, SENS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SENS-specific events.
SENS 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. SENS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SENS alongside the broader basket even when SENS-specific fundamentals are unchanged. Always rebuild the position from current SENS chain quotes before placing a trade.
Frequently asked questions
- What is a straddle on SENS?
- A straddle on SENS is the straddle strategy applied to SENS (stock). The strategy is structurally neutral / high-volatility (long premium): 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. With SENS stock trading near $5.75, the strikes shown on this page are snapped to the nearest listed SENS chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are SENS 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 SENS straddle priced from the end-of-day chain at a 30-day expiry (ATM IV 84.50%), 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 SENS straddle?
- The breakeven for the SENS straddle 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 SENS market-implied 1-standard-deviation expected move is approximately 24.23%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a straddle on SENS?
- Straddles on SENS are pure-volatility plays that profit from large moves in either direction; traders typically buy SENS straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
- How does current SENS implied volatility affect this straddle?
- SENS ATM IV is at 84.50% with IV rank near 19.46%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
