What is Volatility?

In finance, volatility refers to the degree of variation in a trading price series over time, usually measured by the standard deviation of returns. In simpler terms, volatility measures how quickly and how much a stock's price moves up or down.

• High Volatility: A stock with high volatility will have large price swings in a short period. It can be riskier, but also offers the potential for higher returns.
• Low Volatility: A stock with low volatility has a more stable price and moves up and down more gradually.

The VIX: The 'Fear Index'

The CBOE Volatility Index (VIX) is a popular measure of the stock market's expectation of volatility based on S&P 500 index options. It is often called the 'fear index' because it tends to spike when investors are fearful and the market is falling.

Is Volatility Good or Bad?

It's neither. Volatility is a natural part of the market. For long-term investors, short-term volatility is often just noise. For short-term traders, however, volatility can provide opportunities to profit from price swings. Understanding your own risk tolerance is key to dealing with volatility.
