What is a strangle on DNTH?
A long strangle buys an OTM call and an OTM put at offset strikes, cheaper than a straddle but requiring a larger underlying move to profit since both wings start out-of-the-money.
Current DNTH snapshot
As of May 15, 2026, spot at $86.15, ATM IV 57.70%, IV rank 2.26%, expected move 16.54%. The strangle on DNTH 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 98-day expiry.
Why this strangle structure on DNTH specifically: DNTH IV at 57.70% is on the cheap side of its 1-year range, which favors premium-buying structures like a DNTH strangle, with a market-implied 1-standard-deviation move of approximately 16.54% (roughly $14.25 on the underlying). The 98-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DNTH expiries trade a higher absolute premium for lower per-day decay. Position sizing on DNTH should anchor to the underlying notional of $86.15 per share and to the trader's directional view on DNTH stock.
DNTH strangle setup
The DNTH strangle below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With DNTH near $86.15, the first option leg uses a $90.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DNTH chain at a 98-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 DNTH shares for the stock leg in covered calls and collars).
| Action | Type | Strike / Basis | Premium (est) |
|---|---|---|---|
| Buy 1 | Call | $90.00 | $11.85 |
| Buy 1 | Put | $80.00 | $9.65 |

When traders use strangle on DNTH
Strangles on DNTH are the cheaper cousin of the straddle - traders use them when they want a large directional move but are willing to give up the inner-strike sensitivity in exchange for a lower up-front debit on the DNTH chain.
DNTH thesis for this strangle
The market-implied 1-standard-deviation range for DNTH extends from approximately $71.90 on the downside to $100.40 on the upside. A DNTH long strangle is the OTM cousin of the straddle: lower up-front cost but the underlying has to travel further past either OTM strike before the position turns profitable at expiration. Current DNTH IV rank near 2.26% 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 DNTH at 57.70%. As a Healthcare name, DNTH options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DNTH-specific events.
DNTH strangle positions are structurally neutral / high-volatility (long premium, OTM); 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. DNTH positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DNTH alongside the broader basket even when DNTH-specific fundamentals are unchanged. Always rebuild the position from current DNTH chain quotes before placing a trade.
