IV rank (1-year IV percentile) measures where a stock's current 30-day implied volatility sits relative to its own past year: 100 means IV is at a 1-year high, 0 a 1-year low. High IV rank means options premium is historically expensive for that name — relevant for premium-selling strategies — but often for a reason, such as upcoming earnings, FDA decisions, or M&A news.
