What is a long call on ANNX?

A long call buys upside exposure with a fixed maximum loss equal to the premium paid; profit accrues if the underlying closes above the strike plus premium at expiration.

Current ANNX snapshot

As of June 29, 2026, spot at $5.60, ATM IV 350.20%, IV rank 100.00%, expected move 100.40%. The long call on ANNX 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 long call structure on ANNX specifically: ANNX IV at 350.20% is rich versus its 1-year range, which makes a premium-buying ANNX long call relatively expensive in absolute-cost terms, with a market-implied 1-standard-deviation move of approximately 100.40% (roughly $5.62 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 ANNX expiries trade a higher absolute premium for lower per-day decay. Position sizing on ANNX should anchor to the underlying notional of $5.60 per share and to the trader's directional view on ANNX stock.

ANNX long call setup

The ANNX long call below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With ANNX near $5.60, the first option leg uses a $5.60 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ANNX 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 ANNX shares for the stock leg in covered calls and collars).

When traders use long call on ANNX

Long calls on ANNX express a bullish thesis with defined risk; traders use them ahead of ANNX catalysts (earnings, product launches, macro events) when the expected upside justifies the premium and theta decay.

ANNX thesis for this long call

The market-implied 1-standard-deviation range for ANNX extends from approximately $-0.02 on the downside to $11.22 on the upside. A ANNX long call expresses a directional view that the underlying closes above the strike plus premium at expiration, ideally with implied volatility holding or expanding to preserve extrinsic value through the hold period. Current ANNX 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 ANNX at 350.20%. As a Healthcare name, ANNX options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ANNX-specific events.

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