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 straddle on DFTX?
A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the 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 straddle 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 straddle 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 straddle, 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 straddle setup
The DFTX straddle 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 $42.00 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 | $42.00 | $5.10 |
| Buy 1 | Put | $42.00 | $3.85 |

Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit.

When traders use straddle on DFTX
Straddles on DFTX are pure-volatility plays that profit from large moves in either direction; traders typically buy DFTX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
DFTX thesis for this straddle
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 straddle is a pure-volatility play: it profits when the underlying moves far enough from the strike in either direction to overcome the combined call plus put debit, regardless of direction. 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 straddle positions are structurally neutral / high-volatility (long premium); 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 straddle on DFTX?
- A straddle on DFTX is the straddle strategy applied to DFTX (stock). The strategy is structurally neutral / high-volatility (long premium): A long straddle buys an ATM call and an ATM put at the same strike, profiting from a large move in either direction; max loss equals the combined debit when the underlying pins to the 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 straddle max profit and max loss calculated?
- Upside max profit is unbounded; downside max profit is bounded at the strike minus the combined call plus put debit (reached at zero). Max loss equals the combined debit times 100 (reached when the underlying pins to the strike). Two breakevens at strike plus debit and strike minus debit. For the DFTX straddle priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 83.30%), the computed maximum profit is unbounded per contract and the computed maximum loss is -$878.79 per contract. Live intraday quotes will differ as the chain moves through the trading session.
- What is the breakeven for a DFTX straddle?
- The breakeven for the DFTX straddle priced on this page is roughly $33.05 and $50.95 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 straddle on DFTX?
- Straddles on DFTX are pure-volatility plays that profit from large moves in either direction; traders typically buy DFTX straddles ahead of earnings, FDA decisions, or other catalysts where the realized move is expected to exceed the implied move priced into the chain.
- How does current DFTX implied volatility affect this straddle?
- 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.
