Current GKOS snapshot
As of May 15, 2026, spot at $143.92, ATM IV 47.30%, IV rank 30.84%, expected move 13.56%. The bull call spread on GKOS 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 GKOS specifically: GKOS IV at 47.30% is mid-range versus its 1-year history, so strategy selection should anchor more to the directional thesis than to the IV regime, with a market-implied 1-standard-deviation move of approximately 13.56% (roughly $19.52 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 GKOS expiries trade a higher absolute premium for lower per-day decay. Position sizing on GKOS should anchor to the underlying notional of $143.92 per share and to the trader's directional view on GKOS stock.
GKOS bull call spread setup
The GKOS 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 GKOS near $143.92, the first option leg uses a $145.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GKOS 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 GKOS shares for the stock leg in covered calls and collars).

GKOS thesis for this bull call spread
The market-implied 1-standard-deviation range for GKOS extends from approximately $124.40 on the downside to $163.44 on the upside. A GKOS bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on GKOS, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current GKOS IV rank near 30.84% is mid-range against its 1-year distribution, so the IV signal is neutral; the bull call spread thesis on GKOS should anchor more to the directional view and the expected-move geometry. As a Healthcare name, GKOS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GKOS-specific events.
GKOS 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. GKOS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GKOS alongside the broader basket even when GKOS-specific fundamentals are unchanged. Long-premium structures like a bull call spread on GKOS 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 GKOS chain quotes before placing a trade.
