Current KRRO snapshot
As of May 14, 2026, spot at $11.21, ATM IV 181.80%, expected move 52.12%. The collar on KRRO 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 35-day expiry.
Why this collar structure on KRRO specifically: IV rank is unavailable in the current snapshot, so regime-based timing for KRRO is inferred from ATM IV at 181.80% alone, with a market-implied 1-standard-deviation move of approximately 52.12% (roughly $5.84 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated KRRO expiries trade a higher absolute premium for lower per-day decay. Position sizing on KRRO should anchor to the underlying notional of $11.21 per share and to the trader's directional view on KRRO stock.
KRRO collar setup
The KRRO collar below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With KRRO near $11.21, the first option leg uses a $11.77 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed KRRO chain at a 35-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 KRRO shares for the stock leg in covered calls and collars).

KRRO thesis for this collar
The market-implied 1-standard-deviation range for KRRO extends from approximately $5.37 on the downside to $17.05 on the upside. A KRRO collar hedges an existing long KRRO position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. As a Healthcare name, KRRO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to KRRO-specific events.
KRRO collar positions are structurally neutral (protective); 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. KRRO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move KRRO alongside the broader basket even when KRRO-specific fundamentals are unchanged. Always rebuild the position from current KRRO chain quotes before placing a trade.
