问题如下:
Which of the following statements about credit ratings is most accurate?
选项:
A.Credit ratings can migrate over time.
B.Changes in bond credit ratings precede changes in bond prices.
C.Credit ratings are focused on expected loss rather than risk of default.
解释:
A is correct.
Credit migration is the risk that a bond issuer’s creditworthiness deteriorates, or migrates lower. Over time, credit ratings can migrate significantly from what they were at the time a bond was issued. An investor should not assume that an issuer’s credit rating will remain the same from the time of purchase through the entire holding period.
