WebDrawdowns for Brownian motion processes 193 1.2. Definitions While sustaining downside risk can be appropriately characterized using the drawdown process and the first drawdown time, economic turmoil and volatile market fluctuations are better described by quantities containing more pathwise information, such as the frequency of drawdowns. daryl shuttleworthWebX(t) is an (arithmetic) Brownian motion: dX(t) = µdt+ σdW(t) 0 ≤ t ≤ T µ = average return per unit time (drift) σ = std. dev. of the returns per unit time (volatility) dW(t) = Wiener increment (shocks) Note: If the fund S(t) follows a geometric Brownian motion, then the cumulative return sequence follows a Brownian motion. daryl s hutchinson mdWebThe maximum drawdown at time T of a random process on [0,T] can be defined informally as the largest drop from a peak to a trough.
