IV Rank is bounded 0%–100% by construction. Sustained levels above 75% historically
precede mean reversion in SLN'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.
