BILS snapshot
As of August 14, 2026, spot at $99.31, ATM IV 24.20%, IV rank 50.26%, expected move 6.94%. The iron condor on BILS below is built from the 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 iron condor structure on BILS specifically: BILS IV at 24.20% is mid-range versus its 1-year history, so the credit collected on a BILS iron condor sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 6.94% (roughly $6.89 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 BILS expiries trade a higher absolute premium for lower per-day decay. Position sizing on BILS should anchor to the underlying notional of $99.31 per share and to the trader's directional view on BILS etf.
BILS iron condor setup
The BILS iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BILS at $99.31 on that close, the first option leg uses a $104.28 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BILS 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 BILS shares for the stock leg in covered calls and collars).

BILS thesis for this iron condor
The market-implied 1-standard-deviation range for BILS extends from approximately $92.42 on the downside to $106.20 on the upside. A BILS iron condor is a delta-neutral premium-collection structure that pays off when BILS stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current BILS IV rank near 50.26% is mid-range against its 1-year distribution, so the IV signal is neutral; the iron condor thesis on BILS should anchor more to the directional view and the expected-move geometry. As a Financial Services name, BILS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BILS-specific events.
BILS iron condor positions are structurally neutral / range-bound; 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. BILS positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BILS alongside the broader basket even when BILS-specific fundamentals are unchanged. Short-premium structures like a iron condor on BILS carry tail risk when realized volatility exceeds the implied move; review historical BILS earnings reactions and macro stress periods before sizing. Always rebuild the position from current BILS chain quotes before placing a trade.
