Attached is a spreadsheet that shows how the fair value of an index can be calculated. Points to note

  • Recovery rate: Used for DV01 calculation. ITRAXX financial subordinated has 20% recovery constituents, ITRAXX has a mixture of senior (40%) and subordinated, and the rest are all senior
  • Weight: Usually same for all constituents in an index unless a merger has taken place (i.e. Intesa Sanpaolo SpA).
  • Spread: We linearally interpolate the spread if necesary. With the attached example, the S7 ITraxx 5Y XOver matures in 20/06/2012, so we have 4.75 years until maturity (we calculate from next roll date - 20/09/2007).
  • Interest rate: Again, use interpolated interest rate - used for DV01 calcs
  • DV01 - discussed here http://www.noelwatson.com/blog/PermaLink,guid,5c54efd9-9b42-480a-bb1a-01386a2c9d48.aspx

I've written about this a few times before

but the exam on Saturday marked the end of my CQF course. Passing Modules 1-5 exams and completing the Module 6 coursework allows you to obtain a pass, but you need to score more than 80% in the final exam to get a distinction. The results are out in around 2 weeks.

If anyone wants to discuss my thoughts on the course drop me an email.
