一、模型假设 只有现在和未来两个时刻,现在是确定的,未来是不确定的; 假定市场中有n种风险资产,其未来价格是n个随机变量x,x2,xn 第0种资产是无风险资产,其未来价格x是确定值; 假设n+1种资产的当前价格为p(x),px),p(x2),p(xn).这n+1 种资产的投资组合可用n+1维向量=(1)来表示那么投资组 合的当前价格为 p=p(x)+0p(x1)+…+np(xn) 投资组合的未来价格为

APT理论的均衡证明 我们假定一个只有现在和未来两个时刻的两期模型,现在是确定的,未来 是不确定的。假定市场中有n种风险资产,其未来价格是n个随机变量 x1,x2,…,xn;第0种资产是无风险资产,其未来价格x是确定值;n+1种资产 的当前价格为p(x),p(x1)p(x2),p(xn)。这+1种资产的投资组合可用n+1 维向量=(,1,0)来表示
