For CoStar Group, delta 0.20–0.30 is a common range for covered calls. This gives 70–80% probability of the option expiring worthless while collecting meaningful premium. Lower delta (0.15–0.20) is more conservative, while 0.30–0.40 generates more income but has higher assignment probability.

The CC Score (0–100) ranks covered call opportunities across 7 dimensions: Income potential (22%), Safety (18%), Liquidity (18%), Underlying Quality (14%), Event Safety (12%), IV Opportunity (8%), and Execution Quality (8%). Higher scores mean better risk-adjusted opportunities. Sort by CC Score to find the best strike and expiration combo for CoStar Group.

Weekly covered calls (7–14 DTE) offer faster theta decay and more flexibility but require active management. Monthly covered calls (30–45 DTE) balance time premium with less frequent rolling. For CoStar Group, current elevated IV makes both viable — weeklies capture the rich premium faster. The CC Score ranks both DTE ranges so you can compare directly.

The primary risk is capped upside: if CoStar Group rallies sharply, you are obligated to sell at the strike price and miss gains above it. At the current top-ranked $45 strike (12.4% OTM), any rally beyond that level means you sell shares below market price. To contextualize: covered calls are best suited for sideways-to-mildly-bullish outlooks. If you expect a significant move higher, consider waiting to sell the call or using a wider strike. The CC Score penalizes strikes with elevated event risk to help you avoid the worst setups.

CoStar Group currently has an IV Rank of 74%. IV is elevated, meaning option premiums are richer than usual — a favorable environment for selling covered calls. Higher IV translates directly to more income per contract for the same strike distance.

CoStar Group's top covered call shows 30.1% annualized. High annualized returns typically result from elevated IV, shorter DTE (which amplifies annualization), or closer-to-the-money strikes. Always check the CC Score — it penalizes strikes with poor liquidity or excessive event risk that may inflate the headline yield.
