Volatility
Volatility measures how much an asset's price fluctuates over a given period. High volatility means larger price swings; low volatility means a calmer, more predictable price path.
Volatility is typically measured as the standard deviation of price returns over a specified window. Historical volatility is calculated from past price data; implied volatility is derived from options prices and reflects the market's expectation of future volatility.
The VIX (Volatility Index), published by Cboe, measures the implied volatility of S&P 500 options over the next 30 days. It is widely referred to as the "fear gauge" — rising sharply during market stress and declining in calmer periods. Similar indices exist for other markets.
High volatility creates both opportunity and risk. Wider price swings mean larger potential profits for traders with correct directional views, but also larger potential losses. Risk management tools such as stop-loss orders and smaller position sizes become more important in volatile markets.
Asset classes differ substantially in typical volatility. Government bonds are generally low-volatility; single stocks and cryptocurrencies are high-volatility. Even within asset classes, volatility varies: major forex pairs are calmer than exotic pairs; large-cap stocks are less volatile than small-caps.
