A long call butterfly buys one lower-strike call, sells two ATM calls, and buys one higher-strike call, paying a small net debit for a defined-risk position that maxes out if the underlying pins the middle strike at expiration.
DYN snapshot
As of August 14, 2026, spot at $25.80, ATM IV 90.90%, IV rank 18.63%, expected move 26.06%. The butterfly 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 butterfly 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 butterfly, 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 butterfly setup
The DYN butterfly 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 $25.00 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).

| Sell 2 | Call | $26.00 | $1.90 |
| Buy 1 | Call | $27.00 | $2.08 |

When traders use butterfly on DYN
Butterflies on DYN are pinning bets - traders use them when they expect DYN to settle near a specific level at expiration (often the prior close, a round number, or the max-pain strike) and want defined-risk exposure to that outcome.
DYN thesis for this butterfly
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 call butterfly is a pinning play: it pays maximum at the middle strike if DYN settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. 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 butterfly positions are structurally neutral / pin (limited-risk, limited-reward); 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. Always rebuild the position from current DYN chain quotes before placing a trade.
