What is a straddle on STE?
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.
STE snapshot
As of August 14, 2026, spot at $233.12, ATM IV 22.70%, IV rank 4.35%, expected move 6.51%. The straddle on STE 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 35-day expiry.
Why this straddle structure on STE specifically: STE IV at 22.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a STE straddle, with a market-implied 1-standard-deviation move of approximately 6.51% (roughly $15.17 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated STE expiries trade a higher absolute premium for lower per-day decay. Position sizing on STE should anchor to the underlying notional of $233.12 per share and to the trader's directional view on STE stock.
STE straddle setup
The STE 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 STE at $233.12 on that close, the first option leg uses a $230.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STE chain at a 35-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 STE shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $230.00 | $8.40 |
| Buy 1 | Put | $230.00 | $4.60 |

When traders use straddle on STE
Straddles on STE are pure-volatility plays that profit from large moves in either direction; traders typically buy STE straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
STE thesis for this straddle
The market-implied 1-standard-deviation range for STE extends from approximately $217.95 on the downside to $248.29 on the upside. A STE 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 STE IV rank near 4.35% 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 STE at 22.70%. As a Healthcare name, STE options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STE-specific events.
STE 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. STE positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STE alongside the broader basket even when STE-specific fundamentals are unchanged. Always rebuild the position from current STE chain quotes before placing a trade.
