Current CSGP snapshot
As of June 30, 2026, spot at $28.60, ATM IV 54.60%, IV rank 17.12%, expected move 15.65%. The cash-secured put on CSGP 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 80-day expiry.
Why this cash-secured put structure on CSGP specifically: CSGP IV at 54.60% is on the cheap side of its 1-year range, which means a premium-selling CSGP cash-secured put collects less credit per unit of strike-width risk, with a market-implied 1-standard-deviation move of approximately 15.65% (roughly $4.48 on the underlying). The 80-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated CSGP expiries trade a higher absolute premium for lower per-day decay. Position sizing on CSGP should anchor to the underlying notional of $28.60 per share and to the trader's directional view on CSGP stock.
CSGP cash-secured put setup
The CSGP cash-secured put below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With CSGP near $28.60, the first option leg uses a $27.17 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed CSGP chain at a 80-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 CSGP shares for the stock leg in covered calls and collars).

CSGP thesis for this cash-secured put
The market-implied 1-standard-deviation range for CSGP extends from approximately $24.12 on the downside to $33.08 on the upside. A CSGP cash-secured put lets a trader earn premium while waiting to acquire CSGP at the strike price; the strategy is most attractive when the trader is comfortable holding the underlying at that level and IV is rich enough to compensate for the assignment risk. Current CSGP IV rank near 17.12% 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 CSGP at 54.60%. As a Real Estate name, CSGP options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to CSGP-specific events.
CSGP cash-secured put positions are structurally neutral to slightly bullish; 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. CSGP positions also carry Real Estate sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move CSGP alongside the broader basket even when CSGP-specific fundamentals are unchanged. Short-premium structures like a cash-secured put on CSGP carry tail risk when realized volatility exceeds the implied move; review historical CSGP earnings reactions and macro stress periods before sizing. Always rebuild the position from current CSGP chain quotes before placing a trade.
