Current RZLT snapshot

As of June 29, 2026, spot at $5.12, ATM IV 456.90%, IV rank 100.00%, expected move 130.99%. The bull call spread on RZLT 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 18-day expiry.

Why this bull call spread structure on RZLT specifically: RZLT IV at 456.90% is rich versus its 1-year range, which makes a premium-buying RZLT bull call spread relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 130.99% (roughly $6.71 on the underlying). The 18-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated RZLT expiries trade a higher absolute premium for lower per-day decay. Position sizing on RZLT should anchor to the underlying notional of $5.12 per share and to the trader's directional view on RZLT stock.

RZLT bull call spread setup

The RZLT bull call spread below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With RZLT near $5.12, the first option leg uses a $5.12 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed RZLT chain at a 18-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 RZLT shares for the stock leg in covered calls and collars).

A RZLT bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on RZLT, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current RZLT IV rank near 100.00% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on RZLT at 456.90%. As a Healthcare name, RZLT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to RZLT-specific events.

RZLT bull call spread positions are structurally moderately 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. RZLT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move RZLT alongside the broader basket even when RZLT-specific fundamentals are unchanged. Long-premium structures like a bull call spread on RZLT 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.
