How are DFTX long put max profit and max loss calculated?

Max profit equals the strike minus premium times 100 (reached at zero); max loss equals the premium times 100. Breakeven is strike minus premium. For the DFTX long put priced from the August 14, 2026 end-of-day chain at a 30-day expiry (ATM IV 83.30%), the computed maximum profit is $3,814.00 per contract and the computed maximum loss is -$385.00 per contract. Live intraday quotes will differ as the chain moves through the trading session.

What is the breakeven for a DFTX long put?

The breakeven for the DFTX long put priced on this page is roughly $38.15 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.

How does current DFTX implied volatility affect this long put?

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.

DFTX snapshot

As of August 14, 2026, spot at $42.37, ATM IV 83.30%, IV rank 11.51%, expected move 23.88%. The long put 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 long put 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 long put, 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 long put setup

The DFTX long put 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).

When traders use long put on DFTX

Long puts on DFTX hedge an existing long DFTX stock position or express a bearish view with defined risk; position sizing typically scales the put notional to the underlying DFTX exposure being hedged.

DFTX thesis for this long put

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 put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long DFTX position with one put per 100 shares held. 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 long put positions are structurally bearish; 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. Long-premium structures like a long put on DFTX 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 DFTX chain quotes before placing a trade.
