Covariance of the return of two assets

is a measure of the degree or tendency of the two variables to move in relationship with each other. If 2 assets tend to move in the same direction, then they are said to be positively correlated, and they will have a positive covariance.

Correlation coefficient

Like covariance it measures the degree of association between two variables

Perfect negative linear correlation

-1. two assets move in the exact opposite direction

Perfect linear positive correlation

+1. two assets move in the exact same direction and in the same proportion

Spearman rank correlation

based on the ranked size of the variables rather than the absolute size. Rank correlations are sometimes preferred because of the way rank correlation handles the effects of outliers

Beta

measures added systematic risk as a proportion of the risk of the index. The beta of an asset may be viewed as the percentage return response that an asset will have an average to a 1 %age point movement in the related risk factor, such as overall market

Autocorrelation of returns

can be used as a general term to describe possible relationships between the returns of an asset from different time periods.

First order autocorrelation

refers to the correlation between return in time period t and the return in the immediately previous time period t-1
