What is a collar on DNTH?

A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.

DNTH snapshot

As of August 14, 2026, spot at $115.72, ATM IV 56.10%, IV rank 1.68%, expected move 16.08%. The collar on DNTH 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 collar structure on DNTH specifically: IV regime affects collar pricing on both sides; compressed DNTH IV at 56.10% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 16.08% (roughly $18.61 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 DNTH expiries trade a higher absolute premium for lower per-day decay. Position sizing on DNTH should anchor to the underlying notional of $115.72 per share and to the trader's directional view on DNTH stock.

DNTH collar setup

The DNTH collar 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 DNTH at $115.72 on that close, the first option leg uses a $120.00 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 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 DNTH shares for the stock leg in covered calls and collars).

When traders use collar on DNTH

Collars on DNTH hedge an existing long DNTH stock position; the long put sets a floor while the short call finances it, often run as a near-zero-cost hedge during expected volatility windows.

DNTH thesis for this collar

The market-implied 1-standard-deviation range for DNTH extends from approximately $97.11 on the downside to $134.33 on the upside. A DNTH collar hedges an existing long DNTH position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. Current DNTH IV rank near 1.68% 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 56.10%. 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 collar positions are structurally neutral (protective); 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.
