What is a collar on XFOR?

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.

XFOR snapshot

As of August 14, 2026, spot at $4.20, ATM IV 358.60%, IV rank 74.65%, expected move 102.81%. The collar on XFOR below is built from the 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 XFOR specifically: IV regime affects collar pricing on both sides; elevated XFOR IV at 358.60% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 102.81% (roughly $4.32 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 XFOR expiries trade a higher absolute premium for lower per-day decay. Position sizing on XFOR should anchor to the underlying notional of $4.20 per share and to the trader's directional view on XFOR stock.

XFOR collar setup

The XFOR 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 XFOR at $4.20 on that close, the first option leg uses a $4.41 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed XFOR 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 XFOR shares for the stock leg in covered calls and collars).

When traders use collar on XFOR

XFOR thesis for this collar

The market-implied 1-standard-deviation range for XFOR extends from approximately $-0.12 on the downside to $8.52 on the upside. A XFOR collar hedges an existing long XFOR 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 XFOR IV rank near 74.65% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on XFOR at 358.60%. As a Healthcare name, XFOR options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to XFOR-specific events.

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