Comfort Systems USA'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: 0.92.

These three metrics work together — IV Rank shows historical context, VRP shows current overpricing, and RV Ratio shows the volatility trend.
