volatility
含义: The degree of variation in the price of a financial instrument or market index over time; more broadly, the tendency towards rapid and unpredictable change.
In finance, volatility is a statistical measure of the dispersion of returns. High volatility means large price swings and greater uncertainty; low volatility indicates stability. The VIX index, often called the 'fear gauge,' measures expected volatility in the US stock market. Implied volatility is derived from options pricing, while historical volatility looks at past price movements. Beyond finance, the word is used in politics, social commentary, and science (where volatile substances evaporate readily). Common collocations include 'market volatility,' 'price volatility,' and 'heightened volatility.'
