Which of the following is a likely consequence of Kai’s approach to managing his finances?选项：
A.Concentrated portfolio positions
B.Forgone opportunities to reduce risk by combining assets with low correlations
C.Excessive trading
解释：
The most common consequence of mental accounting is neglecting opportunities to reduce risk by combining assets with low correlations, because each account’s asset allocation is examined discretely. Offsetting positions across accounts, or an overall inefficient allocation with respect to risk, can lead to suboptimal aggregate performance.为什么说合并低相关度的资产能降低风险？低相关度不是刚好可以分散风险吗，合并了不是就不能了？
