What is a collar on ALT?
A collar pairs long stock with a protective out-of-the-money put financed by a short out-of-the-money call, capping both tails of the position around the current spot.
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 collar 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 collar structure on ALT specifically: IV regime affects collar pricing on both sides; compressed ALT IV at 65.31% typically pushes the short call premium to roughly offset the long put cost, 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 collar setup
The ALT collar 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 $3.01 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).

|---|---|---|---|

| Buy 1 | Put | $2.73 | N/A |

ALT thesis for this collar
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 collar hedges an existing long ALT position with a protective put while financing the put cost via a short call; when the premiums roughly offset, the collar acts as a near-zero-cost insurance band around the current spot. 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 collar positions are structurally neutral (protective); 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. Always rebuild the position from current ALT chain quotes before placing a trade.
