Current INMB snapshot
As of May 15, 2026, spot at $1.57, ATM IV 127.70%, IV rank 19.53%, expected move 36.61%. The cash-secured put on INMB 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 INMB specifically: INMB IV at 127.70% is on the cheap side of its 1-year range, which means a premium-selling INMB cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 36.61% (roughly $0.57 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 INMB expiries trade a higher absolute premium for lower per-day decay. Position sizing on INMB should anchor to the underlying notional of $1.57 per share and to the trader's directional view on INMB stock.
INMB cash-secured put setup
The INMB 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 INMB near $1.57, the first option leg uses a $1.49 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed INMB 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 INMB shares for the stock leg in covered calls and collars).

INMB thesis for this cash-secured put
The market-implied 1-standard-deviation range for INMB extends from approximately $1.00 on the downside to $2.14 on the upside. A INMB cash-secured put lets a trader earn premium while waiting to acquire INMB 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 INMB IV rank near 19.53% 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 INMB at 127.70%. As a Healthcare name, INMB options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to INMB-specific events.
INMB 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. INMB positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move INMB alongside the broader basket even when INMB-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on INMB carry tail risk when realized volatility exceeds the implied move; review historical INMB earnings reactions and macro stress periods before sizing. Always rebuild the position from current INMB chain quotes before placing a trade.
