CoStar Group Inc. shows moderately favorable conditions for premium selling. Yang-Zhang realized volatility reads 60.8% over 20 days versus a 47.7% 60-day baseline. The RV Ratio (HV 20d / IV 30d) is 0.86, indicating calming conditions relative to implied expectations. A Real Estate sector component tracked by VolRadar. For premium sellers tracking CSGP, this ratio suggests options are likely priced for more movement than the stock is currently delivering.
CSGP has maintained a consistent volatility profile over the past 18 trading days. The RV ratio has held in a range of 1.24 to 1.37, with 0% of days in seller-favorable territory. Stable regimes can persist for weeks in real estate stocks, making CSGP a relatively predictable candidate for premium selling strategies during this period.
Based on current realized volatility, traders can expect CSGP to move approximately ±$1.40 (3.8%) per day and ±$3.14 (8.6%) over five trading days. At a stock price of $36.61, these ranges are derived from the Yang-Zhang volatility model which accounts for overnight gaps and intraday range — more accurate than simple close-to-close calculations. Premium sellers typically place short strikes outside these 1-standard-deviation ranges to achieve approximately 68%+ probability of profit.

CoStar Group Inc. currently shows a strong premium selling signal with an RV Ratio of 0.86. Realized volatility is below implied volatility, suggesting options may be overpriced relative to actual price movement.
CoStar Group Inc.'s volatility is measured using two key metrics. The RV Ratio compares realized volatility (ORATS HV 20d) to implied volatility (IV 30d). When the RV Ratio drops below 0.85, realized movement is well below what options are pricing — the sweet spot for premium sellers. VRP (Volatility Risk Premium) measures the gap between IV and HV in percentage points — positive VRP means options are overpriced relative to actual movement. Current RV Ratio: 0.86.
CoStar Group Inc.'s snapshot: IV Rank 93% (elevated premiums), VRP +9.8pp (options overpriced), RV Ratio 0.86 (normal volatility). These three metrics work together — IV Rank shows historical context, VRP shows current overpricing, and RV Ratio shows the volatility trend. See the IV Analysis page for peer comparisons and deeper breakdown.

Every options trade carries risk: undefined-risk strategies (naked puts/calls) expose you to large losses on gap moves, while defined-risk strategies cap losses but reduce premium. For CoStar Group Inc., current conditions favor premium sellers, but all options trades carry significant risk — always size positions so no single trade risks more than 1-3% of your account. Use the Strategy Builder to model worst-case scenarios before entering.
An IV Rank of 93% means CoStar Group Inc.'s current implied volatility is higher than most readings over the past year. Elevated IV can indicate the market expects larger moves ahead, creating higher premiums for sellers but also higher risk if the move materializes.
CoStar Group Inc.'s Volatility Risk Premium (VRP) is +9.8pp, meaning implied volatility exceeds realized volatility by that amount. A positive VRP indicates options are overpriced relative to actual stock movement — this is the statistical edge premium sellers seek.
Higher RV Ratio (closer to 1.0) means IV barely exceeds RV, resulting in slimmer VRP edge. Lower RV Ratio = wider gap between IV and actual movement = stronger seller edge.
