问题如下:
Following are some descriptions about aggregate fixed-income index, which is correct?
选项:
A.An aggregate fixed-income index represents the government-issued securities market.
B.An aggregate fixed-income index consists of both corporate and asset-backed securities.
C.One can subdivide an aggregate fixed-income index by market or economic sector to get narrowly defined indices.
解释:
C is correct.
One could create more narrowly defined indices by subdivide an aggregate fixed-income index by characteristics like market sector (government, government agency, collateralized, corporate), style (maturity, credit quality), economic sector, etc.
考点:债券指数
aggregate fixed-income index就是broad market indexes,简单来说就是债券的大盘指数包括了按各种维度划分的债券。所以选项A和B错在它说的太片面了。
C是什么意思?可否解释一下?
