What is a strangle on SEM?

A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.

Current SEM snapshot

As of June 30, 2026, spot at $16.52, ATM IV 288.00%, IV rank 62.97%, expected move 82.57%. The strangle on SEM 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 17-day expiry.

Why this strangle structure on SEM specifically: SEM IV at 288.00% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 82.57% (roughly $13.64 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated SEM expiries trade a higher absolute premium for lower per-day decay. Position sizing on SEM should anchor to the underlying notional of $16.52 per share and to the trader's directional view on SEM stock.

SEM strangle setup

The SEM strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With SEM near $16.52, the first option leg uses a $17.35 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SEM chain at a 17-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 SEM shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 1	Call	$17.35	N/A
Buy 1	Put	$15.69	N/A

SEM strangle risk and reward

Net Premium / Debit: N/A
Max Profit (per contract): Unbounded
Max Loss (per contract): Unbounded
Breakeven(s): None on modeled curve
Risk / Reward Ratio: N/A

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.

When traders use strangle on SEM

Strangles on SEM 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 SEM chain.

SEM thesis for this strangle

The market-implied 1-standard-deviation range for SEM extends from approximately $2.88 on the downside to $30.16 on the upside. A SEM 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 SEM IV rank near 62.97% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on SEM should anchor more to the directional view and the expected-move geometry. As a Healthcare name, SEM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SEM-specific events.

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