Portfolio Standard Deviation is calculated based on the standard deviation of returns of each asset in the portfolio, the proportion of each asset in the overall portfolio, i.e., their respective weights in the total portfolio, and also the correlation between each pair of assets in the portfolio.

2022年1月16日 · 要计算投资组合的标准差，我们需要三个参数：投资组合中每个股票或基金的标准差，每个股票或基金在该投资组合中的占比，以及所有每对股票或基金之间的相关系数。 下面的公式是计算由两个股票或基金组成的投资组合的标准差。 我们这里假设组合中都是股票。 事实上组合中可以是股票，基金， 指数基金 等。 这里WA，WB分别代表股票A和B的占比。 σ (KA)和σ (KB)分别代表股票A和B的标准差。 R (KA,KB)代表股票A和B的相关系数。 那么现在的问题是 …
