问题如下:
Which of Avelyn’s comments regarding considerations in the bottom-up approach is most accurate?
选项:
A.Comment 1
B.Comment 2
C.Comment 3
解释:
C is correct.
When an issuer announces a new corporate bond issue, the issuer’s existing bonds often decline in value and their spreads widen. This dynamic is often explained by market participants as an effect of increased supply. A related reason is that because demand is not perfectly elastic, new issues are often given a price concession to entice borrowers to buy the new bonds. This price concession may result in all of an issuer’s existing bonds repricing based on the new issue’s relatively wider spread. A third reason is that more debt issuance may signal an increase in an issuer’s credit risk.
老师我来顺一下
不管PUTABLE 和 callable 他们的OAS 理论上应该和同等条件只是缺少这两个权利的bond的 OAS相等。
然后一般的BOND 的 z spread 基本是等于 OAS的
所以在比较的时候, callable 因为含有对投资者不利的权力,所以价格低,所以同等cash flow 情况下,下面的折现率要更大,才会使得价格变小,所以callable 的 OAS 大于 同等 bond 的OAS 即同等 bond的 Z spread,这样理解对吗?
