volatility
How much and how fast prices jump around. Calm markets move a little; wild markets move a lot.
The fuller meaning
The size of price swings over a period, measured by ATR, standard deviation or Bollinger Band width, and in options by implied volatility. Low volatility often precedes bigger moves; high volatility widens stops and shrinks position size for the same risk.
