ABOS Butterfly Strategy
ABOS (Acumen Pharmaceuticals, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
Acumen Pharmaceuticals Inc. operates as a biopharmaceutical entity in the clinical development stage, dedicated to discovering and advancing therapeutic solutions for Alzheimer's disease. A key focus for the company involves progressing ACU193, an investigational targeted immunotherapy drug candidate. This particular humanized monoclonal antibody is currently undergoing initial human testing in Phase I clinical trials, where it is designed to specifically target soluble amyloid-beta oligomers. The firm was established in 1996 and maintains its principal headquarters in Charlottesville, Virginia.
ABOS (Acumen Pharmaceuticals, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $143.0M, a beta of 0.35 versus the broader market, a 52-week range of 1.1-3.6, average daily share volume of 460K, a public-listing history dating back to 2021, approximately 61 full-time employees. These structural characteristics shape how ABOS stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.35 indicates ABOS has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure.
What is a butterfly on ABOS?
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 ABOS snapshot
As of June 30, 2026, spot at $2.69, ATM IV 367.00%, IV rank 100.00%, expected move 105.22%. The butterfly on ABOS 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 17-day expiry.
Why this butterfly structure on ABOS specifically: ABOS IV at 367.00% is rich versus its 1-year range, which makes a premium-buying ABOS butterfly relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 105.22% (roughly $2.83 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ABOS expiries trade a higher absolute premium for lower per-day decay. Position sizing on ABOS should anchor to the underlying notional of $2.69 per share and to the trader's directional view on ABOS stock.
ABOS butterfly setup
The ABOS 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 ABOS near $2.69, the first option leg uses a $2.56 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ABOS chain at a 17-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 ABOS shares for the stock leg in covered calls and collars).

|---|---|---|---|

When traders use butterfly on ABOS
Butterflies on ABOS are pinning bets - traders use them when they expect ABOS 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.
ABOS thesis for this butterfly
The market-implied 1-standard-deviation range for ABOS extends from approximately $-0.14 on the downside to $5.52 on the upside. A ABOS long call butterfly is a pinning play: it pays maximum at the middle strike if ABOS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current ABOS IV rank near 100.00% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on ABOS at 367.00%. As a Healthcare name, ABOS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ABOS-specific events.
ABOS 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. ABOS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ABOS alongside the broader basket even when ABOS-specific fundamentals are unchanged. Always rebuild the position from current ABOS chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on ABOS?
- A butterfly on ABOS is the butterfly strategy applied to ABOS (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 ABOS stock trading near $2.69, the strikes shown on this page are snapped to the nearest listed ABOS chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are ABOS 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 ABOS butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 367.00%), 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 ABOS butterfly?
- The breakeven for the ABOS 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 ABOS market-implied 1-standard-deviation expected move is approximately 105.22%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
