What implied volatility tells you

Implied volatility (IV) is the market's forecast of how much REGN is expected to move, expressed as an annualized percentage and backed out of the price traders are actually paying for REGN options.

Higher IV means options are pricing in bigger expected swings and cost more; lower IV means the market expects calmer conditions and options are cheaper.

High or low for REGN?

IV percentile is the share of the past year's daily IV readings that sit below today's IV. A percentile above 80 means REGN's current IV is richer than at least 80% of the last year, i.e. statistically high. Below 20 means it's statistically cheap.

This is different from IV rank, which places today's IV between the past year's high and low instead of counting where it falls in the full distribution; a single outlier spike can distort rank without moving percentile.

IV vs realized: the premium

The volatility risk premium (VRP) is implied volatility minus realized volatility. A positive VRP means REGN options have been priced above the moves that actually happened, the edge options sellers try to harvest. See VRP for the full breakdown.
