 Volatility: implied volatility, stock volatility, option volatility
Volatility is typically expressed in annualized terms, and it may either be an absolute number (5$) or a fraction of the initial value (5%).
For a financial instrument whose price follows a Gaussian random walk, or Wiener process, the volatility increases by the square-root of time as time increases.
Note that the formula used to annualize returns is not deterministic, but is an extrapolation valid for a random walk process whose steps have finite variance.
