ALLO (Allogene Therapeutics, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $568.2M, a beta of 0.46 versus the broader market, a 52-week range of 0.94-4.46, average daily share volume of 9.6M, a public-listing history dating back to 2018, approximately 226 full-time employees. These structural characteristics shape how ALLO stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.

What is a butterfly on ALLO?
A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
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 butterfly 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 butterfly 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 butterfly, 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 butterfly setup
The ALLO butterfly 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 $1.90 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).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $1.90 | N/A |
| Sell 2 | Call | $2.00 | N/A |
| Buy 1 | Call | $2.10 | N/A |

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

When traders use butterfly on ALLO
Butterflies on ALLO are pinning bets - traders use them when they expect ALLO to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
ALLO thesis for this butterfly
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 long call butterfly is a pinning play: it pays maximum at the middle strike if ALLO settles there at expiration, with the wing legs capping both the cost and the maximum loss to the 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 butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. Always rebuild the position from current ALLO chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on ALLO?
- A butterfly on ALLO is the butterfly strategy applied to ALLO (stock). The strategy is structurally neutral / pin (limited-risk, limited-reward): A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration. With ALLO stock trading near $2.00, the strikes shown on this page are snapped to the nearest listed ALLO chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are ALLO butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the ALLO butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 49.20%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a ALLO butterfly?
- The breakeven for the ALLO butterfly 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 ALLO market-implied 1-standard-deviation expected move is approximately 14.11%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on ALLO?
- Butterflies on ALLO are pinning bets - traders use them when they expect ALLO to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
- How does current ALLO implied volatility affect this butterfly?
- ALLO ATM IV is at 49.20% with IV rank near 6.72%, which is on the low end of its 1-year range. Premium-buying structures (long call, long put, debit spreads) are relatively cheap in this regime; premium-selling structures collect less credit per unit risk.
