The fund's goal is to track as closely as possible, before fees and expenses, the total return of an index that measures the performance of large U.S. companies based on their fundamental size and weight.
FNDX (Schwab Fundamental U.S. Large Company Index ETF) trades in the Financial Services sector, specifically Asset Management, with a market capitalization of approximately $25.98B, a beta of 0.86 versus the broader market, a 52-week range of 23.18-30.51, average daily share volume of 6.7M, a public-listing history dating back to 2013.

What is a butterfly on FNDX?
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 FNDX snapshot
As of May 15, 2026, spot at $30.30, ATM IV 22.20%, IV rank 37.02%, expected move 6.36%. The butterfly on FNDX 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 FNDX specifically: FNDX IV at 22.20% 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 6.36% (roughly $1.93 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 FNDX expiries trade a higher absolute premium for lower per-day decay. Position sizing on FNDX should anchor to the underlying notional of $30.30 per share and to the trader's directional view on FNDX etf.
FNDX butterfly setup
The FNDX 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 FNDX near $30.30, the first option leg uses a $28.79 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FNDX 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 FNDX shares for the stock leg in covered calls and collars).

|---|---|---|---|
| Buy 1 | Call | $28.79 | N/A |
| Sell 2 | Call | $30.30 | N/A |
| Buy 1 | Call | $31.82 | N/A |

When traders use butterfly on FNDX
Butterflies on FNDX are pinning bets - traders use them when they expect FNDX 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.
FNDX thesis for this butterfly
The market-implied 1-standard-deviation range for FNDX extends from approximately $28.37 on the downside to $32.23 on the upside. A FNDX long call butterfly is a pinning play: it pays maximum at the middle strike if FNDX settles there at expiration, with the wing legs capping both the cost and the maximum loss to the net debit. Current FNDX IV rank near 37.02% is mid-range against its 1-year distribution, so the IV signal is neutral; the butterfly thesis on FNDX should anchor more to the directional view and the expected-move geometry. As a Financial Services name, FNDX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FNDX-specific events.
FNDX 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. FNDX positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FNDX alongside the broader basket even when FNDX-specific fundamentals are unchanged. Always rebuild the position from current FNDX chain quotes before placing a trade.
Frequently asked questions
- What is a butterfly on FNDX?
- A butterfly on FNDX is the butterfly strategy applied to FNDX (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 FNDX etf trading near $30.30, the strikes shown on this page are snapped to the nearest listed FNDX chain strike and the premiums come straight from the end-of-day bid/ask midpoint.
- How are FNDX 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 FNDX butterfly priced from the end-of-day chain at a 30-day expiry (ATM IV 22.20%), 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.
- What is the breakeven for a FNDX butterfly?
- The breakeven for the FNDX 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 FNDX market-implied 1-standard-deviation expected move is approximately 6.36%; if the move sits well outside the breakeven distance, the structure's risk-reward becomes correspondingly tighter.
