Maximum diversification benefit can be achieved if one were to
form a portfolio of two stocks whose returns had a correlation
coefficient of:
-1.0 |
+1.0 |
0.0 |
none of the above |
The correct answer is -1.0
Maximum benefit from diversification occurs when the correlation coefficient for pairs of stocks is minus one.
Diversification benefit - We should not invest our wealth in a
single stock. We should invest in a portfolio. Whenever we combine
two or more assets in a portfolio the risk gets reduced. The extent
of risk reduction depends on correlation.
Correlation refers to the strength of liner relationship between
two variables. It lies between -1 and +1. Lower the
correlation, greater the benefit of diversification in the form of
risk reduction. Therefore maximum benefit from diversification will
occur when correlation coefficient is -1.
