What is a strangle on ALDX?
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 ALDX snapshot
As of May 15, 2026, spot at $1.65, ATM IV 139.80%, IV rank 20.16%, expected move 40.08%. The strangle on ALDX 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 28-day expiry.
Why this strangle structure on ALDX specifically: ALDX IV at 139.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a ALDX strangle, with a market-implied 1-standard-deviation move of approximately 40.08% (roughly $0.66 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ALDX expiries trade a higher absolute premium for lower per-day decay. Position sizing on ALDX should anchor to the underlying notional of $1.65 per share and to the trader's directional view on ALDX stock.
ALDX strangle setup
The ALDX 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 ALDX near $1.65, the first option leg uses a $1.73 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ALDX chain at a 28-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 ALDX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $1.73 | N/A |
| Buy 1 | Put | $1.57 | N/A |
ALDX strangle risk and reward

- N/A
- Max Profit (per contract)
- Unbounded
- Max Loss (per contract)

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 ALDX
Strangles on ALDX 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 ALDX chain.
ALDX thesis for this strangle
The market-implied 1-standard-deviation range for ALDX extends from approximately $0.99 on the downside to $2.31 on the upside. A ALDX 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 ALDX IV rank near 20.16% 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 ALDX at 139.80%. As a Healthcare name, ALDX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ALDX-specific events.
ALDX 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. ALDX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ALDX alongside the broader basket even when ALDX-specific fundamentals are unchanged. Always rebuild the position from current ALDX chain quotes before placing a trade.
Frequently asked questions
- What is a strangle on ALDX?
- A strangle on ALDX is the strangle strategy applied to ALDX (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 ALDX stock trading near $1.65, the strikes shown on this page are snapped to the nearest listed ALDX chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are ALDX strangle max profit and max loss calculated?

Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a ALDX strangle?
- The breakeven for the ALDX strangle 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 ALDX market-implied 1-standard-deviation expected move is approximately 40.08%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a strangle on ALDX?
- Strangles on ALDX 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 ALDX chain.
