CBOE NASDAQ Volatility Index

CBOE NASDAQ Volatility Index

A mathematical measure of the implied volatility of options trading on NASDAQ 100. The VXN attempts to measure the likelihood of option prices to vary unpredictably in the context of the Black-Scholes model. A higher number on the index represents greater volatility, while a lower number represents lower volatility. While critics maintain that its usefulness is overstated, the index is considered an indicator of option volatility in the wider market. See also: VIX.
