What is a collar on ANRO?
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 ANRO snapshot
As of May 15, 2026, spot at $22.96, ATM IV 83.40%, IV rank 13.31%, expected move 23.91%. The collar on ANRO 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 collar structure on ANRO specifically: IV regime affects collar pricing on both sides; compressed ANRO IV at 83.40% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 23.91% (roughly $5.49 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 ANRO expiries trade a higher absolute premium for lower per-day decay. Position sizing on ANRO should anchor to the underlying notional of $22.96 per share and to the trader's directional view on ANRO stock.
ANRO collar setup
The ANRO 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 ANRO near $22.96, the first option leg uses a $24.11 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ANRO 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 ANRO shares for the stock leg in covered calls and collars).

| Buy 100 shares | Stock | $22.96 | long |
| Sell 1 | Call | $24.11 | N/A |
| Buy 1 | Put | $21.81 | N/A |

ANRO thesis for this collar
The market-implied 1-standard-deviation range for ANRO extends from approximately $17.47 on the downside to $28.45 on the upside. A ANRO collar hedges an existing long ANRO 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 ANRO IV rank near 13.31% 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 ANRO at 83.40%. As a Healthcare name, ANRO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ANRO-specific events.
ANRO 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. ANRO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ANRO alongside the broader basket even when ANRO-specific fundamentals are unchanged. Always rebuild the position from current ANRO chain quotes before placing a trade.
