What is a strangle on CENX?
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 CENX snapshot
As of May 15, 2026, spot at $57.06, ATM IV 75.70%, IV rank 49.78%, expected move 21.70%. The strangle on CENX 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 strangle structure on CENX specifically: CENX IV at 75.70% 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 21.70% (roughly $12.38 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 CENX expiries trade a higher absolute premium for lower per-day decay. Position sizing on CENX should anchor to the underlying notional of $57.06 per share and to the trader's directional view on CENX stock.
CENX strangle setup
The CENX 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 CENX near $57.06, the first option leg uses a $60.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CENX 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 CENX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $60.00 | $4.10 |
| Buy 1 | Put | $55.00 | $4.15 |

When traders use strangle on CENX
Strangles on CENX 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 CENX chain.
CENX thesis for this strangle
The market-implied 1-standard-deviation range for CENX extends from approximately $44.68 on the downside to $69.44 on the upside. A CENX 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 CENX IV rank near 49.78% is mid-range against its 1-year distribution, so the IV signal is neutral; the strangle thesis on CENX should anchor more to the directional view and the expected-move geometry. As a Basic Materials name, CENX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CENX-specific events.
CENX 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. CENX positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CENX alongside the broader basket even when CENX-specific fundamentals are unchanged. Always rebuild the position from current CENX chain quotes before placing a trade.
