Is this the Nomura paper that you are looking for? I think there are newer paper from other ibs that talk about 'base' correlation.John,
Do you have any recent Credit Derivative guide from JPM (circa 2007) or correlation paper from Nomura. There is a quantitative analyst at Nomura named Michiko Whetten Ph.D. Program in Business - Michiko Whetten/Finance
She is a faculty at Baruch as well. I tried to email to both her work and Baruch email but they both bounced. She has a few interesting research papers that relevant to my work.

I use a newer paper from Nomura. It's on Securitization.net at

The interesting part is that most papers use data from around May 05 (CDX series 4) when Ford, GM default and turn the whole credit world upside down.
By the way, did you hear about Markit aquired IIC and now owns right to all the itraxx index ? Interestingly, Tim Grant is UBS representative on the IIC board. I talked to him today and his group does quite a lot of index/tranche trading as well.
Here is another paper from Citigroup on NYU website that is pretty relevant to tranche relative value trading.

This is quite good and recent paper, John. Base correlation is all we have at this moment. We use Copula to calibrate from tranche spreads and back out to find base correlation. We have models to find tranche correlation too but most of the time, the model fails to calibrate at the mezz and super senior tranches.My colleague gave me this paper from Barcap: it has a section showing how to value bespoke tranches with base correlations ;-)
Spread is really choppy. Liquidity is shot. Dealers that we used to get quotes from are no longer providing liquidity. Less trades but with greater nominal when we find good trades.how's your group doing given all the volatility lately. I heard that the bid/ask for index like ABX jumps all over the place.
