Consider the pairwise correlations of monthly returns of the following asset classes:
Based solely on the information in the above table, which equity asset class is most sharply distinguished from US equities?
选项:
A.Brazilian equities.
B.European equities.
C.East Asian equities.
解释:
A is correct.
The correlation between US equities and Brazilian equities is 0.76. The correlations between US equities and East Asian equities and the correlation between US equities and European equities both exceed 0.76. Lower correlations indicate a greater degree of separation between asset classes. Therefore, using solely the data given in the table, returns on Brazilian equities are most sharply distinguished from returns on US equities.
