标题: [求助] CFA L1 Fixed Income 问题请教

Schweser June 08 Exam 1 Morning

112. Consider a callable bond issued by Stahl Productions and a putable bond issued by Hearth Creations. Both bonds have option-adjusted spreads of 125 basis points. Which of the following statements about the bonds (from the issuer perspective) could be accurate?

A. The z-spread for Hearth's bond is based on the differences in YTMs.

B. The cost of the put option on the Hearth bond is -10 bp.

C. The spread over the spot rates for a Treasury security similar to Stahl's bond is 110 bp.

D. Given a nominal spread for the Stahl bond of 130 bp, the option cost is 5 bp.

The answer is B.

Why is D not the answer?

D不对吧，因为option cost = Z-spred - Option adjusted spread.如果D选项中nominal spread 改成Z-spread 我估计就对了。
