同学你好,这个就是 蒙特卡洛模拟里dS = uSdt+ σSdz这个公式的应用。代入本题数据,得到 dS = 0.14*S*ε*根号下0.01 =0.014*S*ε 。也就是说,
S1 = S0 + dS1 = S0 + 0.014*S0*ε = S0*(1+0.014*0.263),然后S2=S1 + dS2。
本质就是一个递推式。

谢谢您!

为什么dz=ε*根号下0.01? 老师讲课的时候不是说dz=ε*σ吗?

我知道了,不用回答了,谢谢。

NO.PZ2016062402000027 ift term的计算不懂,题目中给的0,为啥计算机过程中显示1?
请问,本题中的波动率是什么时间跨度?t=0.01是什么时间跨度?
有对应的课件页数和截图吗?没找到呀
