DFTX Butterfly Strategy
DFTX (Definium Therapeutics, Inc.), in the Healthcare sector, (Biotechnology industry), listed on NASDAQ.
Definium Therapeutics, Inc. operates as a clinical-stage biopharmaceutical firm dedicated to developing innovative therapeutic solutions for various brain health and neurological disorders. Its pipeline features key experimental drug candidates like MM120, which is currently undergoing Phase 3 clinical trials for generalized anxiety disorder (GAD) and attention deficit hyperactivity disorder (ADHD). Another significant compound, MM402 – an R-enantiomer of 3,4-methylenedioxymethamphetamine – is in Phase 1 trials, targeting the fundamental symptoms of autism spectrum disorder. The company maintains its headquarters in New York, New York.
DFTX (Definium Therapeutics, Inc.) trades in the Healthcare sector, specifically Biotechnology, with a market capitalization of approximately $5.68B, a beta of 2.24 versus the broader market, a 52-week range of 12.882-49.2, average daily share volume of 2.6M, a public-listing history dating back to 2016, approximately 106 full-time employees. These structural characteristics shape how DFTX stock options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 2.24 indicates DFTX has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position.
What is a butterfly on DFTX?
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.
DFTX snapshot
As of August 14, 2026, spot at $42.37, ATM IV 83.30%, IV rank 11.51%, expected move 23.88%. The butterfly on DFTX below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this butterfly structure on DFTX specifically: DFTX IV at 83.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a DFTX butterfly, with a market-implied 1-standard-deviation move of approximately 23.88% (roughly $10.12 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DFTX expiries trade a higher absolute premium for lower per-day decay. Position sizing on DFTX should anchor to the underlying notional of $42.37 per share and to the trader's directional view on DFTX stock.
DFTX butterfly setup
The DFTX butterfly below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With DFTX at $42.37 on that close, the first option leg uses a $40.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DFTX chain at a 35-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 DFTX shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $40.00 | $5.65 |
| Sell 2 | Call | $42.00 | $5.10 |
| Buy 1 | Call | $44.00 | $4.33 |
DFTX butterfly risk and reward

- $206.29
- Max Loss (per contract)
- $22.50
- Breakeven(s)

When traders use butterfly on DFTX
Butterflies on DFTX are pinning bets - traders use them when they expect DFTX 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.
DFTX thesis for this butterfly
The market-implied 1-standard-deviation range for DFTX extends from approximately $32.25 on the downside to $52.49 on the upside. A DFTX long call butterfly is a pinning play: it pays maximum at the middle strike if DFTX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current DFTX IV rank near 11.51% 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 DFTX at 83.30%. As a Healthcare name, DFTX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DFTX-specific events.
DFTX 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. DFTX positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DFTX alongside the broader basket even when DFTX-specific fundamentals are unchanged. Always rebuild the position from current DFTX chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on DFTX?
- A butterfly on DFTX is the butterfly strategy applied to DFTX (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 DFTX stock at $42.37 on the August 14, 2026 close, the strikes shown on this page are snapped to the nearest listed DFTX chain strike and the premiums come straight from that session's bid/ask midpoint.
- How are DFTX 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 DFTX butterfly priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 83.30%), the computed maximum profit is $206.29 per contract and the computed maximum loss is $22.50 per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a DFTX butterfly?
- The breakeven for the DFTX butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from the August 14, 2026 end-of-day chain's premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The DFTX market-implied 1-standard-deviation expected move in the same options snapshot is approximately 23.88%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
- When should you consider a butterfly on DFTX?
- Butterflies on DFTX are pinning bets - traders use them when they expect DFTX 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 DFTX implied volatility affect this butterfly?
- DFTX ATM IV is at 83.30% with IV rank near 11.51%, 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.
