Volatility is a word that is used to describe how quickly and drastically things can change. It is often used in the context of the stock market, where it refers to how much a stock's price fluctuates over a period of time. If a stock is considered volatile, it means that its price can change dramatically in a short period of time, making it a riskier investment. The term can also be used more generally to describe anything that is unstable or unpredictable, such as the weather or someone's mood. As an English learner, it's important to understand the concept of volatility if you are reading about finance, economics, or other fields where this term is commonly used.
