本文发表在 rolia.net 枫下论坛通常, 各种资产的相关性用Correlation Coefficient (相关系数) 表示. Correlation Coefficient = Covariance / (Standard deviation of asst 1 x Standard deviation of asset 2). Correlation Coefficient在[-1, 1]. 如果Correlation Coefficient = 1, 则两资产正关联, 有相同的波动周期; 如果Correlation Coefficient = -1, 则两资产负关联, 有相反的波动周期; 如果Correlation Coefficient = 0, 则两资产无关联.
这里贴不上表格, 很不方便. 只列举一些数据. Correlation Coefficient (S&P/TSX and Government Bond) = -0.07, Correlation Coefficient (S&P/TSX and Cdn High Yield) = 0.54, Correlation Coefficient (S&P/TSX and Real Property) = -0.13, Correlation Coefficient (S&P/TSX and Mortgage Fund) = -0.01, Correlation Coefficient (Real Property and Government Bond) = 0.28, Correlation Coefficient (Cdn High Yield and Government Bond) = -0.14, Correlation Coefficient (Corporate Bond Fund and Government Bond) = 0.9. Quarterly data Jan 1/97 – March/04.
这都是书本上的知识. 正如过去的表现不能代表以后的回报; 以前的关联也不能代表以后的关联性. 投资是动态的, 需要监控, 平衡和调整.
