Volatility
Volatility measures how strongly the value of an investment fluctuates over time. It is often used as an indicator of an investment's risk; high volatility means larger price swings both upwards and downwards. Volatility says something about the range of fluctuation, not about the direction of future performance. Past fluctuation is not a reliable indicator of future performance.
