Current GHRS snapshot
As of May 15, 2026, spot at $21.54, ATM IV 72.90%, IV rank 5.39%, expected move 20.90%. The bull call spread on GHRS 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 bull call spread structure on GHRS specifically: GHRS IV at 72.90% is on the cheap side of its 1-year range, which favors premium-buying structures like a GHRS bull call spread, with a market-implied 1-standard-deviation move of approximately 20.90% (roughly $4.50 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 GHRS expiries trade a higher absolute premium for lower per-day decay. Position sizing on GHRS should anchor to the underlying notional of $21.54 per share and to the trader's directional view on GHRS stock.
GHRS bull call spread setup
The GHRS 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 GHRS near $21.54, the first option leg uses a $21.54 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GHRS 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 GHRS shares for the stock leg in covered calls and collars).

GHRS thesis for this bull call spread
The market-implied 1-standard-deviation range for GHRS extends from approximately $17.04 on the downside to $26.04 on the upside. A GHRS bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on GHRS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current GHRS IV rank near 5.39% 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 GHRS at 72.90%. As a Healthcare name, GHRS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GHRS-specific events.
GHRS 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. GHRS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GHRS alongside the broader basket even when GHRS-specific fundamentals are unchanged. Long-premium structures like a bull call spread on GHRS 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 GHRS chain quotes before placing a trade.
