问题如下:
Suppose you simulate the price
path of stock HHF using a geometric Brownian motion model with drift μ = 0,
volatility σ = 0.14, and time step Δt = 0.01. Let St be the price of the stock at
time t. If S0 = 100, and the first two simulated (randomly selected) standard
normal variables are ε1 = 0.263 andε2 = -0.475, what is the simulated stock price after the second step?
选项:
A.96.79
99.79
99.97
99.70
解释:
The process for the
stock prices has mean of zero and volatility of Hence the first step is
The second step is
