Cummins — Implied volatility rank, VRP edge, and volatility regime
Cummins (CMI) is a Industrials stock with actively traded listed options. Its IV Rank reads 47.0%, mid-range within the past year — neither cheap nor rich.

IV Rank above 50 generally favors premium sellers — you're collecting above-average premium.

Higher IV Rank means relatively richer premiums compared to each stock's own history.

Cummins's IV Rank of 47.0% places premiums in the middle of the 252-day range — neither particularly rich nor cheap. At moderate IV Rank, premium sellers can still find opportunities but should be more selective about strategy and timing. Focus on tickers where VRP confirms overpricing and where the RV regime supports selling. Credit spreads and iron condors work well at moderate IV Rank because they reduce capital requirement while maintaining positive expected value.
Cummins's IV Rank measures where current implied volatility sits relative to its 252-day range. At 47.0%, it indicates how rich or cheap options premiums are compared to the past year. Premium sellers generally prefer IV Rank above 30–50%, as higher IV means more premium per contract and a greater statistical edge — assuming VRP confirms actual overpricing.
Cummins's IV Rank of 47.0% exceeds its Industrials peers, suggesting stock-specific factors are driving elevated premiums.

Sector peers for comparison: GNRC (59%), ALLE (33%), UPS (32%). This sector-relative premium makes Cummins a candidate for premium selling even if the sector's overall IV environment is moderate.
VolRadar's signal prioritizes relative mispricing (RV Ratio) over absolute premium level (IV Rank). A ticker with low IVR but very low RV Ratio may show a Strong signal because options are significantly overpriced relative to actual movement. For richest absolute premiums, check IV Rank (>50%).

Cummins's volatility is calculated using the Yang-Zhang estimator, which incorporates overnight gaps, opening range, and intraday movement — more accurate than simple close-to-close calculations for stocks with significant pre/post-market activity. The RV Ratio (0.95) compares realized volatility (HV 20d) to implied volatility (IV 30d). Below 0.85 means actual movement is well below what options are pricing in — favorable for premium sellers.
