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:
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
由于B答案的convexity小于C答案,所以less protection from twist 和shift。为什么C错呢
