问题如下：
Based
on Exhibit 2, relative to Portfolio C, Portfolio B:
选项：
A.has higher cash flow reinvestment risk.
B.is a more desirable portfolio for liquidity management.
C.provides less protection from yield curve shifts and twists.
解释：
Correct Answer: B
B is correct. Portfolio B is a laddered portfolio with maturities spread more or less evenly over the yield curve. A desirable aspect of a laddered portfolio is liquidity management. Because there is always a bond close to redemption, the soon-to-mature bond can provide emergency liquidity needs. Barbell portfolios, such as Portfolio C, have maturities only at the short-term and long-term ends and thus are much less desirable for liquidity management.
按我的理解应该是bullet最小 barbell最大 laddered居中？
因为barbell有一笔11.5年的要一直给它再投资再投资 所以Reinvestment return的不确定性就比较大？
