Current BKU snapshot
As of May 15, 2026, spot at $45.31, ATM IV 33.70%, IV rank 3.51%, expected move 9.66%. The cash-secured put on BKU 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 cash-secured put structure on BKU specifically: BKU IV at 33.70% is on the cheap side of its 1-year range, which means a premium-selling BKU cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 9.66% (roughly $4.38 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 BKU expiries trade a higher absolute premium for lower per-day decay. Position sizing on BKU should anchor to the underlying notional of $45.31 per share and to the trader's directional view on BKU stock.
BKU cash-secured put setup
The BKU cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BKU near $45.31, the first option leg uses a $43.04 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BKU 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 BKU shares for the stock leg in covered calls and collars).

BKU thesis for this cash-secured put
The market-implied 1-standard-deviation range for BKU extends from approximately $40.93 on the downside to $49.69 on the upside. A BKU cash-secured put lets a trader earn premium while waiting to acquire BKU 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 BKU IV rank near 3.51% 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 BKU at 33.70%. As a Financial Services name, BKU options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BKU-specific events.
BKU 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. BKU positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BKU alongside the broader basket even when BKU-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on BKU carry tail risk when realized volatility exceeds the implied move; review historical BKU earnings reactions and macro stress periods before sizing. Always rebuild the position from current BKU chain quotes before placing a trade.
