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 bull call spread 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 bull call spread 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 bull call spread setup

The CENX bull call spread 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 $55.00 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).

CENX thesis for this bull call spread

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 bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on CENX, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current CENX IV rank near 49.78% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread 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 bull call spread positions are structurally moderately bullish; 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. Long-premium structures like a bull call spread on CENX are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current CENX chain quotes before placing a trade.
