IV Rank is bounded 0%–100% by construction. Sustained levels above 75% historically precede mean reversion in MCO's implied vol; sustained sub-25% readings often coincide with low-realized regimes ahead of catalyst events. See the Vol Arb Screener for symbols where current IV rank diverges most from realized volatility.
