WebbMeaning if two assets have a correlation coefficient of 0.4 they have a slightly positive correlation. The strength of the correlation may not be as strong as a third asset that may have a 0.85 correlation with the first asset. Anything above a +0.8 correlation between two assets is considered strong, anything below -0.8 is very weak.
