题目
In a two-asset portfolio, reducing the correlation between the two assets moves the efficient frontier in which direction?
选项
A.The efficient frontier is stable unless return expectations change. If expectations change, the efficient frontier will extend to the upper right with little or no change in risk.
B.The efficient frontier tends to move down and to the left, representing increased risk from negative correlation.
C.The frontier extends to the left, or northwest quadrant representing a reduction in risk while maintaining or enhancing portfolio returns.
D.The efficient frontier is stable unless the asset’s expected volatility changes. This depends on each asset’s standard deviation.
答案
C
解析
Reducing correlation between the two assets results in the efficient frontier expanding to the left and possibly slightly upward. This reflects the influence of correlation on reducing portfolio risk.减少这两种资产之间的相关性会导致有效边界向左扩展，并可能略微向上扩展。 这反映了相关性对降低投资组合风险的影响。
