Question Which of the following most accurately describes the basis for construction of nearly all bond market indexes?选项：
A.Dealer prices B.Model prices C.Market prices解释：
SolutionA is correct. Firms (dealers) are assigned to specific securities and are responsible for creating liquid markets for those securities by purchasing and selling them from their inventory. In addition, many securities do not trade frequently and, as a result, are relatively illiquid. As a result, index providers must contact dealers to obtain current prices on constituent securities to update the index, or they must estimate the prices of constituent securities using the prices of traded fixed-income securities with similar characteristics.
B is incorrect. Fixed-income markets are predominantly dealer markets, and many securities do not trade frequently.
C is incorrect. Many fixed-income securities do not trade frequently. Though index providers may estimate the prices of constituent securities using prices of traded fixed-income securities with similar characteristics, fixed-income markets are predominantly dealer markets.
