Current ADUR snapshot
As of May 15, 2026, spot at $13.85, ATM IV 85.70%, IV rank 13.98%, expected move 24.57%. The bull call spread on ADUR 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 ADUR specifically: ADUR IV at 85.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a ADUR bull call spread, with a market-implied 1-standard-deviation move of approximately 24.57% (roughly $3.40 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 ADUR expiries trade a higher absolute premium for lower per-day decay. Position sizing on ADUR should anchor to the underlying notional of $13.85 per share and to the trader's directional view on ADUR stock.
ADUR bull call spread setup
The ADUR 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 ADUR near $13.85, the first option leg uses a $13.85 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ADUR 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 ADUR shares for the stock leg in covered calls and collars).

ADUR thesis for this bull call spread
The market-implied 1-standard-deviation range for ADUR extends from approximately $10.45 on the downside to $17.25 on the upside. A ADUR bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on ADUR, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current ADUR IV rank near 13.98% 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 ADUR at 85.70%. As a Basic Materials name, ADUR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ADUR-specific events.
ADUR 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. ADUR positions also carry Basic Materials sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ADUR alongside the broader basket even when ADUR-specific fundamentals are unchanged. Long-premium structures like a bull call spread on ADUR 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 ADUR chain quotes before placing a trade.
