Current UPB snapshot
As of May 15, 2026, spot at $9.05, ATM IV 166.60%, IV rank 36.89%, expected move 47.76%. The cash-secured put on UPB 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 UPB specifically: UPB IV at 166.60% is mid-range versus its 1-year history, so the credit collected on a UPB cash-secured put sits in line with its long-run distribution, with a market-implied 1-standard-deviation move of approximately 47.76% (roughly $4.32 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 UPB expiries trade a higher absolute premium for lower per-day decay. Position sizing on UPB should anchor to the underlying notional of $9.05 per share and to the trader's directional view on UPB stock.
UPB cash-secured put setup
The UPB 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 UPB near $9.05, the first option leg uses a $8.60 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed UPB 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 UPB shares for the stock leg in covered calls and collars).

UPB thesis for this cash-secured put
The market-implied 1-standard-deviation range for UPB extends from approximately $4.73 on the downside to $13.37 on the upside. A UPB cash-secured put lets a trader earn premium while waiting to acquire UPB 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 UPB IV rank near 36.89% is mid-range against its 1-year distribution, so the IV signal is neutral; the cash-secured put thesis on UPB should anchor more to the directional view and the expected-move geometry. As a Healthcare name, UPB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to UPB-specific events.
UPB 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. UPB positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move UPB alongside the broader basket even when UPB-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on UPB carry tail risk when realized volatility exceeds the implied move; review historical UPB earnings reactions and macro stress periods before sizing. Always rebuild the position from current UPB chain quotes before placing a trade.
