Current SION snapshot
As of May 15, 2026, spot at $40.22, ATM IV 97.30%, expected move 27.89%. The cash-secured put on SION 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 SION specifically: IV rank is unavailable in the current snapshot, so regime-based timing for SION is inferred from ATM IV at 97.30% alone, with a market-implied 1-standard-deviation move of approximately 27.89% (roughly $11.22 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 SION expiries trade a higher absolute premium for lower per-day decay. Position sizing on SION should anchor to the underlying notional of $40.22 per share and to the trader's directional view on SION stock.
SION cash-secured put setup
The SION 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 SION near $40.22, the first option leg uses a $38.21 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed SION 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 SION shares for the stock leg in covered calls and collars).

SION thesis for this cash-secured put
The market-implied 1-standard-deviation range for SION extends from approximately $29.00 on the downside to $51.44 on the upside. A SION cash-secured put lets a trader earn premium while waiting to acquire SION 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. As a Healthcare name, SION options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to SION-specific events.
SION 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. SION positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move SION alongside the broader basket even when SION-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on SION carry tail risk when realized volatility exceeds the implied move; review historical SION earnings reactions and macro stress periods before sizing. Always rebuild the position from current SION chain quotes before placing a trade.
