GRBK (Green Brick Partners, Inc.) trades in the Consumer Cyclical sector, specifically Residential Construction, with a market capitalization of approximately $3.46B, a trailing P/E of 11.65, a beta of 1.82 versus the broader market, a 52-week range of 60.44-83.18, average daily share volume of 244K, a public-listing history dating back to 2007, approximately 650 full-time employees.

A beta of 1.82 indicates GRBK has historically moved more than the broader market, amplifying both the directional payoff and the realized volatility relative to an index-equivalent position. The trailing P/E of 11.65 is on the value side, where IV often compresses outside event windows because forward growth expectations are already discounted into the share price.
What is a collar on GRBK?
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 GRBK snapshot
As of June 30, 2026, spot at $79.50, ATM IV 32.20%, IV rank 27.97%, expected move 9.23%. The collar on GRBK 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 17-day expiry.
Why this collar structure on GRBK specifically: IV regime affects collar pricing on both sides; compressed GRBK IV at 32.20% typically pushes the short call premium to roughly offset the long put cost, with a market-implied 1-standard-deviation move of approximately 9.23% (roughly $7.34 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated GRBK expiries trade a higher absolute premium for lower per-day decay. Position sizing on GRBK should anchor to the underlying notional of $79.50 per share and to the trader's directional view on GRBK stock.
GRBK collar setup
The GRBK 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 GRBK near $79.50, the first option leg uses a $83.48 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed GRBK chain at a 17-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 GRBK shares for the stock leg in covered calls and collars).

GRBK thesis for this collar
The market-implied 1-standard-deviation range for GRBK extends from approximately $72.16 on the downside to $86.84 on the upside. A GRBK collar hedges an existing long GRBK 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 GRBK IV rank near 27.97% 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 GRBK at 32.20%. As a Consumer Cyclical name, GRBK options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to GRBK-specific events.
GRBK 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. GRBK positions also carry Consumer Cyclical sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move GRBK alongside the broader basket even when GRBK-specific fundamentals are unchanged. Always rebuild the position from current GRBK chain quotes before placing a trade.
