What is a strangle on STEM?
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.
STEM snapshot
As of August 14, 2026, spot at $6.21, ATM IV 113.50%, IV rank 40.76%, expected move 32.54%. The strangle on STEM below is built from the 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 strangle structure on STEM specifically: STEM IV at 113.50% 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 32.54% (roughly $2.02 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 STEM expiries trade a higher absolute premium for lower per-day decay. Position sizing on STEM should anchor to the underlying notional of $6.21 per share and to the trader's directional view on STEM stock.
STEM strangle setup
The STEM 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 STEM at $6.21 on that close, the first option leg uses a $6.52 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed STEM 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 STEM shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $6.52 | N/A |
| Buy 1 | Put | $5.90 | N/A |
STEM 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 STEM
Strangles on STEM 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 STEM chain.
STEM thesis for this strangle
The market-implied 1-standard-deviation range for STEM extends from approximately $4.19 on the downside to $8.23 on the upside. A STEM 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 STEM IV rank near 40.76% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on STEM should anchor more to the directional view and the expected-move geometry. As a Technology name, STEM options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to STEM-specific events.
STEM 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. STEM positions also carry Technology sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move STEM alongside the broader basket even when STEM-specific fundamentals are unchanged. Always rebuild the position from current STEM chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on STEM?
- A strangle on STEM is the strangle strategy applied to STEM (stock). The strategy is structurally neutral / high-volatility (long premium, OTM): 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. With STEM stock at $6.21 on the most recent close, the strikes shown on this page are snapped to the nearest listed STEM chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are STEM strangle max profit and max loss calculated?
- 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. For the STEM strangle priced from the end-of-day chain at a 30-day expiry (ATM IV 113.50%), 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 STEM strangle?
- The breakeven for the STEM strangle priced on this page is no defined breakeven on the modeled curve at expiration, derived from the end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The STEM market-implied 1-standard-deviation expected move in the same options snapshot is approximately 32.54%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on STEM?
- Strangles on STEM 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 STEM chain.
- How does current STEM implied volatility affect this strangle?
- STEM ATM IV is at 113.50% with IV rank near 40.76%, which is mid-range against its 1-year history. Strategy selection depends more on directional thesis and expected move than on a strong IV signal.
