XBI snapshot

As of August 14, 2026, spot at $157.35, ATM IV 27.28%, IV rank 20.70%, expected move 7.82%. The cash-secured put on XBI 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 28-day expiry.

Why this cash-secured put structure on XBI specifically: XBI IV at 27.28% is on the cheap side of its 1-year range, which means a premium-selling XBI cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 7.82% (roughly $12.31 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated XBI expiries trade a higher absolute premium for lower per-day decay.

XBI cash-secured put setup

The XBI cash-secured put 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 XBI at $157.35 on that close, the first option leg uses a $149.50 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XBI chain at a 28-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 XBI shares for the stock leg in covered calls and collars).

Cash-secured puts on XBI earn premium while a trader waits to acquire XBI etf at a target strike below the current quote; most attractive when IV is rich and the trader is comfortable owning XBI.

XBI thesis for this cash-secured put

The market-implied 1-standard-deviation range for XBI extends from approximately $145.04 on the downside to $169.66 on the upside. A XBI cash-secured put lets a trader earn premium while waiting to acquire XBI at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current XBI IV rank near 20.70% 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 XBI at 27.28%. As a Financial Services name, XBI options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XBI-specific events.

XBI cash-secured put positions are structurally neutral to slightly bullish; 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. XBI positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move XBI alongside the broader basket even when XBI-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on XBI carry tail risk when realized volatility exceeds the implied move; review historical XBI earnings reactions and macro stress periods before sizing. Always rebuild the position from current XBI chain quotes before placing a trade.
