Current COYA snapshot
As of May 15, 2026, spot at $5.02, ATM IV 98.30%, IV rank 19.78%, expected move 28.18%. The bull call spread on COYA 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 COYA specifically: COYA IV at 98.30% is on the cheap side of its 1-year range, which favors premium-buying structures like a COYA bull call spread, with a market-implied 1-standard-deviation move of approximately 28.18% (roughly $1.41 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 COYA expiries trade a higher absolute premium for lower per-day decay. Position sizing on COYA should anchor to the underlying notional of $5.02 per share and to the trader's directional view on COYA stock.
COYA bull call spread setup
The COYA 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 COYA near $5.02, the first option leg uses a $5.02 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed COYA 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 COYA shares for the stock leg in covered calls and collars).

COYA thesis for this bull call spread
The market-implied 1-standard-deviation range for COYA extends from approximately $3.61 on the downside to $6.43 on the upside. A COYA bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on COYA, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current COYA IV rank near 19.78% 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 COYA at 98.30%. As a Healthcare name, COYA options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to COYA-specific events.
COYA 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. COYA positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move COYA alongside the broader basket even when COYA-specific fundamentals are unchanged. Long-premium structures like a bull call spread on COYA 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 COYA chain quotes before placing a trade.
