Author	Topic: CB portfolio delta
meriwether @2004-08-26 13:08:17	Dear all, I need help. How do I calculate the delta of a convertible bond portfolio? We have around 50 holdings. Premium is 35%. 60% trade at the bond floor - delta small, 10-15% in the money - delta >.5. Do I estimate the delta for each holding and find a weighted average? Or extrapolate from the portfolio premium? Thanks for your help.

Dear all,

We have around 50 holdings. Premium is 35%. 60% trade at the bond floor - delta small, 10-15% in the money - delta >.5.

Do I estimate the delta for each holding and find a weighted average? Or extrapolate from the portfolio premium?

Thanks for your help.

I passed! I did not get a chance to tell you before the exam - but your site was excellent. I will definitely take it next year for Level II.
