What is a collar on ATOS?
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 ATOS snapshot
As of May 15, 2026, spot at $4.87, ATM IV 132.80%, IV rank 35.35%, expected move 38.07%. The collar on ATOS 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 ATOS specifically: IV regime affects collar pricing on both sides; mid-range ATOS IV at 132.80% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 38.07% (roughly $1.85 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 ATOS expiries trade a higher absolute premium for lower per-day decay. Position sizing on ATOS should anchor to the underlying notional of $4.87 per share and to the trader's directional view on ATOS stock.
ATOS collar setup
The ATOS 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 ATOS near $4.87, the first option leg uses a $5.11 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed ATOS 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 ATOS shares for the stock leg in covered calls and collars).

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

| Buy 1 | Put | $4.63 | N/A |

ATOS thesis for this collar
The market-implied 1-standard-deviation range for ATOS extends from approximately $3.02 on the downside to $6.72 on the upside. A ATOS collar hedges an existing long ATOS 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 ATOS IV rank near 35.35% is mid-range against its 1-year distribution, so the IV signal is neutral; the collar thesis on ATOS should anchor more to the directional view and the expected-move geometry. As a Healthcare name, ATOS options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to ATOS-specific events.
ATOS 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. ATOS positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move ATOS alongside the broader basket even when ATOS-specific fundamentals are unchanged. Always rebuild the position from current ATOS chain quotes before placing a trade.
