Current CRBN snapshot

As of May 15, 2026, spot at $248.91, ATM IV 12.80%, IV rank 1.21%, expected move 3.67%. The long put on CRBN 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 long put structure on CRBN specifically: CRBN IV at 12.80% is on the cheap side of its 1-year range, which favors premium-buying structures like a CRBN long put, with a market-implied 1-standard-deviation move of approximately 3.67% (roughly $9.13 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 CRBN expiries trade a higher absolute premium for lower per-day decay. Position sizing on CRBN should anchor to the underlying notional of $248.91 per share and to the trader's directional view on CRBN etf.

CRBN long put setup

The CRBN long 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 CRBN near $248.91, the first option leg uses a $250.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CRBN 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 CRBN shares for the stock leg in covered calls and collars).

CRBN thesis for this long put

The market-implied 1-standard-deviation range for CRBN extends from approximately $239.78 on the downside to $258.04 on the upside. A CRBN long put expresses a directional view that the underlying closes below the strike minus premium at expiration, frequently sized to hedge an existing long CRBN position with one put per 100 shares held. Current CRBN IV rank near 1.21% 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 CRBN at 12.80%. As a Financial Services name, CRBN options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CRBN-specific events.

CRBN long put positions are structurally bearish; 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. CRBN positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CRBN alongside the broader basket even when CRBN-specific fundamentals are unchanged. Long-premium structures like a long put on CRBN are particularly exposed to IV-crush risk through scheduled events (earnings, FDA decisions, central-bank meetings) where IV typically contracts post-event regardless of the directional outcome. Always rebuild the position from current CRBN chain quotes before placing a trade.
