Current CRL snapshot

As of June 30, 2026, spot at $226.50, ATM IV 48.80%, IV rank 32.75%, expected move 13.99%. The collar on CRL 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 17-day expiry.

Why this collar structure on CRL specifically: IV regime affects collar pricing on both sides; mid-range CRL IV at 48.80% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 13.99% (roughly $31.69 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CRL expiries trade a higher absolute premium for lower per-day decay. Position sizing on CRL should anchor to the underlying notional of $226.50 per share and to the trader's directional view on CRL stock.

CRL collar setup

The CRL 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 CRL near $226.50, the first option leg uses a $240.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CRL chain at a 17-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 CRL shares for the stock leg in covered calls and collars).

When traders use collar on CRL

Collars on CRL hedge an existing long CRL stock position; the long put sets a floor while the short call finances it, often run as a near-zero-cost hedge during expected volatility windows.

CRL thesis for this collar

The market-implied 1-standard-deviation range for CRL extends from approximately $194.81 on the downside to $258.19 on the upside. A CRL collar hedges an existing long CRL 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. Current CRL IV rank near 32.75% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on CRL should anchor more to the directional view and the expected-move geometry. As a Healthcare name, CRL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CRL-specific events.

CRL 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. CRL positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CRL alongside the broader basket even when CRL-specific fundamentals are unchanged. Always rebuild the position from current CRL chain quotes before placing a trade.
