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.
Current DFAS snapshot
As of May 15, 2026, spot at $75.75, ATM IV 20.80%, IV rank 28.15%, expected move 5.96%. The butterfly on DFAS 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 34-day expiry.
Why this butterfly structure on DFAS specifically: DFAS IV at 20.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a DFAS butterfly, with a market-implied 1-standard-deviation move of approximately 5.96% (roughly $4.52 on the underlying). The 34-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated DFAS expiries trade a higher absolute premium for lower per-day decay. Position sizing on DFAS should anchor to the underlying notional of $75.75 per share and to the trader's directional view on DFAS etf.
DFAS butterfly setup
The DFAS butterfly below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With DFAS near $75.75, the first option leg uses a $72.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DFAS chain at a 34-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 DFAS shares for the stock leg in covered calls and collars).

| Sell 2 | Call | $76.00 | $2.30 |
| Buy 1 | Call | $80.00 | $0.67 |

When traders use butterfly on DFAS
Butterflies on DFAS are pinning bets - traders use them when they expect DFAS 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.
DFAS thesis for this butterfly
The market-implied 1-standard-deviation range for DFAS extends from approximately $71.23 on the downside to $80.27 on the upside. A DFAS long call butterfly is a pinning play: it pays maximum at the middle strike if DFAS settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current DFAS IV rank near 28.15% 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 DFAS at 20.80%. As a Financial Services name, DFAS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DFAS-specific events.
DFAS 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. DFAS positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DFAS alongside the broader basket even when DFAS-specific fundamentals are unchanged. Always rebuild the position from current DFAS chain quotes before placing a trade.
