All right? I mean, I can make money at Harvard Square doing this stuff, right?
对不对?【鼓掌】我意思是,我可以在哈佛广场,靠做这个赚钱对不对?
What we want to do now is compute the mean and variance of the portfolio-- or the mean and standard deviation, since standard deviation is the square root of the variance-- for different combinations of the portfolios.
我们现在要做的是,计算这个投资组合的均值和方差-,或者均值和标准差,因为标准差的平方就等于方差-,这对任何投资组合都是一样的。
