Current ALT snapshot
As of May 15, 2026, spot at $2.87, ATM IV 65.31%, IV rank 5.05%, expected move 18.72%. The long call on ALT 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 28-day expiry.
Why this long call structure on ALT specifically: ALT IV at 65.31% is on the cheap side of its 1-year range, which favors premium-buying structures like a ALT long call, with a market-implied 1-standard-deviation move of approximately 18.72% (roughly $0.54 on the underlying). The 28-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated ALT expiries trade a higher absolute premium for lower per-day decay. Position sizing on ALT should anchor to the underlying notional of $2.87 per share and to the trader's directional view on ALT stock.
ALT long call setup
The ALT 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 ALT near $2.87, the first option leg uses a $2.87 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ALT chain at a 28-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 ALT shares for the stock leg in covered calls and collars).

ALT thesis for this long call
The market-implied 1-standard-deviation range for ALT extends from approximately $2.33 on the downside to $3.41 on the upside. A ALT 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 ALT IV rank near 5.05% 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 ALT at 65.31%. As a Healthcare name, ALT options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ALT-specific events.
ALT 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. ALT positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ALT alongside the broader basket even when ALT-specific fundamentals are unchanged. Long-premium structures like a long call on ALT 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 ALT chain quotes before placing a trade.
