FULC snapshot
As of August 14, 2026, spot at $3.73, ATM IV 36.10%, IV rank 5.08%, expected move 10.35%. The bull call spread on FULC below is built from the end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.
Why this bull call spread structure on FULC specifically: FULC IV at 36.10% is on the cheap side of its 1-year range, which favors premium-buying structures like a FULC bull call spread, with a market-implied 1-standard-deviation move of approximately 10.35% (roughly $0.39 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated FULC expiries trade a higher absolute premium for lower per-day decay. Position sizing on FULC should anchor to the underlying notional of $3.73 per share and to the trader's directional view on FULC stock.
FULC bull call spread setup
The FULC 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 FULC at $3.73 on that close, the first option leg uses a $3.73 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed FULC chain at a 35-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 FULC shares for the stock leg in covered calls and collars).

FULC thesis for this bull call spread
The market-implied 1-standard-deviation range for FULC extends from approximately $3.34 on the downside to $4.12 on the upside. A FULC bull call spread caps both the risk and the reward of a bullish position; relative to an outright long call on FULC, the spread reduces the cost basis but limits the maximum profit to the strike width minus net debit. Current FULC IV rank near 5.08% 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 FULC at 36.10%. As a Healthcare name, FULC options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to FULC-specific events.
FULC 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. FULC positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move FULC alongside the broader basket even when FULC-specific fundamentals are unchanged. Long-premium structures like a bull call spread on FULC 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 FULC chain quotes before placing a trade.
