HALO snapshot

As of August 14, 2026, spot at $98.53, ATM IV 32.00%, IV rank 4.23%, expected move 9.17%. The collar on HALO below is built from the August 14, 2026 end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 35-day expiry.

Why this collar structure on HALO specifically: IV regime affects collar pricing on both sides; compressed HALO IV at 32.00% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 9.17% (roughly $9.04 on the underlying). The 35-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated HALO expiries trade a higher absolute premium for lower per-day decay. Position sizing on HALO should anchor to the underlying notional of $98.53 per share and to the trader's directional view on HALO stock.

HALO collar setup

The HALO collar below is built from the August 14, 2026 end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With HALO at $98.53 on that close, the first option leg uses a $105.00 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed HALO chain at a 35-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 HALO shares for the stock leg in covered calls and collars).

Action	Type	Strike / Basis	Premium (est)
Buy 100 shares	Stock	$98.53	long
Sell 1	Call	$105.00	$1.70
Buy 1	Put	$95.00	$2.38

When traders use collar on HALO

Collars on HALO hedge an existing long HALO stock position; the long put sets a floor while the short call finances it, often run as a near-zero-cost hedge during expected volatility windows.

HALO thesis for this collar

The market-implied 1-standard-deviation range for HALO extends from approximately $89.49 on the downside to $107.57 on the upside. A HALO collar hedges an existing long HALO 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 HALO IV rank near 4.23% 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 HALO at 32.00%. As a Healthcare name, HALO options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to HALO-specific events.

HALO 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. HALO positions also carry Healthcare sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move HALO alongside the broader basket even when HALO-specific fundamentals are unchanged. Always rebuild the position from current HALO chain quotes before placing a trade.
