The breakeven for the DYN long put priced on this page is roughly $23.25 at expiration, derived from the August 14, 2026 end-of-day chain's premiums.

DYN snapshot

As of August 14, 2026, spot at $25.80, ATM IV 90.90%, IV rank 18.63%, expected move 26.06%. The long put on DYN 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 DYN specifically: DYN IV at 90.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a DYN long put, with a market-implied 1-standard-deviation move of approximately 26.06% (roughly $6.72 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 DYN expiries trade a higher absolute premium for lower per-day decay. Position sizing on DYN should anchor to the underlying notional of $25.80 per share and to the trader's directional view on DYN stock.

DYN long put setup

The DYN 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 DYN at $25.80 on that close, the first option leg uses a $26.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DYN 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 DYN shares for the stock leg in covered calls and collars).

When traders use long put on DYN

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

DYN thesis for this long put

The market-implied 1-standard-deviation range for DYN extends from approximately $19.08 on the downside to $32.52 on the upside. A DYN long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long DYN position with one put per 100 shares held. Current DYN IV rank near 18.63% 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 DYN at 90.90%. As a Healthcare name, DYN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DYN-specific events.

DYN 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. DYN positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DYN alongside the broader basket even when DYN-specific fundamentals are unchanged. Long-premium structures like a long put on DYN 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 DYN chain quotes before placing a trade.
