What is a bull call spread on ALLO?
A bull call spread buys an at-the-money call and sells an out-of-the-money call at a higher strike for defined risk and defined reward bounded by the strike width.
Current ALLO snapshot
As of May 15, 2026, spot at $2.00, ATM IV 49.20%, IV rank 6.72%, expected move 14.11%. The bull call spread on ALLO 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 ALLO specifically: ALLO IV at 49.20% is on the cheap side of its 1-year range, which favors premium-buying structures like a ALLO bull call spread, with a market-implied 1-standard-deviation move of approximately 14.11% (roughly $0.28 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 ALLO expiries trade a higher absolute premium for lower per-day decay. Position sizing on ALLO should anchor to the underlying notional of $2.00 per share and to the trader's directional view on ALLO stock.
ALLO bull call spread setup
The ALLO 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 ALLO near $2.00, the first option leg uses a $2.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ALLO 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 ALLO shares for the stock leg in covered calls and collars).

ALLO thesis for this bull call spread
The market-implied 1-standard-deviation range for ALLO extends from approximately $1.72 on the downside to $2.28 on the upside. A ALLO bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on ALLO, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current ALLO IV rank near 6.72% 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 ALLO at 49.20%. As a Healthcare name, ALLO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ALLO-specific events.
ALLO 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. ALLO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ALLO alongside the broader basket even when ALLO-specific fundamentals are unchanged. Long-premium structures like a bull call spread on ALLO 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 ALLO chain quotes before placing a trade.
