As a non-fundamental policy, under normal circumstances, it will invest at least 80% of its net assets in equity securities of U.S. companies. The Advisor may also increase or reduce the fund's exposure to an eligible company, or exclude a company, based on shorter-term considerations, such as a company's price momentum and investment characteristics.

What is a butterfly on DFAU?
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 DFAU snapshot
As of May 15, 2026, spot at $50.78, ATM IV 27.10%, IV rank 30.16%, expected move 7.77%. The butterfly on DFAU 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 DFAU specifically: DFAU IV at 27.10% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 7.77% (roughly $3.95 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 DFAU expiries trade a higher absolute premium for lower per-day decay. Position sizing on DFAU should anchor to the underlying notional of $50.78 per share and to the trader's directional view on DFAU etf.
DFAU butterfly setup
The DFAU 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 DFAU near $50.78, the first option leg uses a $48.24 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed DFAU 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 DFAU shares for the stock leg in covered calls and collars).

|---|---|---|---|

DFAU thesis for this butterfly
The market-implied 1-standard-deviation range for DFAU extends from approximately $46.83 on the downside to $54.73 on the upside. A DFAU long call butterfly is a pinning play: it pays maximum at the middle strike if DFAU settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current DFAU IV rank near 30.16% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on DFAU should anchor more to the directional view and the expected-move geometry. As a Financial Services name, DFAU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to DFAU-specific events.
DFAU 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. DFAU positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move DFAU alongside the broader basket even when DFAU-specific fundamentals are unchanged. Always rebuild the position from current DFAU chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on DFAU?
- A butterfly on DFAU is the butterfly strategy applied to DFAU (etf). The strategy is structurally neutral / pin (limited-risk, limited-reward): 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. With DFAU etf trading near $50.78, the strikes shown on this page are snapped to the nearest listed DFAU chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are DFAU butterfly max profit and max loss calculated?
- Max profit equals the wing width minus net debit times 100 (reached when the underlying pins the middle strike); max loss equals the net debit times 100. Two breakevens at lower-wing plus debit and upper-wing minus debit. For the DFAU butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 27.10%), the computed maximum profit is unbounded per contract and the computed maximum loss is unbounded per contract. Live intraday quotes will differ as the chain moves through the trading session.

- The breakeven for the DFAU butterfly priced on this page is no defined breakeven on the modeled curve at expiration, derived from end-of-day chain premiums. Breakeven is the underlying price at which the strategy's P&L crosses zero ignoring transaction costs and assignment risk. The current DFAU market-implied 1-standard-deviation expected move is approximately 7.77%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
