PCA and independence of the residuals

I think you may be barking up the wrong tree. PCA is a method for obtaining orthogonalized vectors for replicating the original data to various degrees depending on the number of eigenvectors chosen. Not sure where the residuals come into the picture.

Pricing CMS Spread Range Accrual Note

Looks like the USD 2-10 spread is finally going to invert, I wonder how are those people holding callable spread range accrual conditional upon a positive curve is feeling now!?

New trends in interest rate exotic products

<t>QuoteOriginally posted by: bmYes, we do a few of these products. One variant is a callable spread accrual note. In note form the investor gets say a fixed rate that only accrues on days (months) where the defined spread is within a limit; for example the €15y swap rate minus the €2y swap rate is ...

Calculating CMS rate on short term rate tree

<t>Kim, for the bermudan on a CMS-Libor swap, using a short-rate tree should also be possible and it should not be unuseably slow. Since there is no closed-form solution for the CMS rate on any node of the tree, it must be computed by pricing the swap on the sub-tree conditonal upon that node being ...

Pricing of libor exotics

<r>Hi ajeetkc,Do not be dispair. The reason why no one can send you a calculator for Callable Range Accrual is partly because there are so many decisions one have to make to get the final value. LIBOR Market Model is a good framework but to get the most efficient implementation for a structure, ofte...

Credit Default Swaption

<t>Kr,I most definitely agree with you. The CDS market is still in it's infancy, anyone who wish to delta hedge a CDS option has gotta factor in an enormous hedging cost. For some ref entities, just crossing the spread will cost you an arm and a leg. I am constantly surprised when dealers found out ...

Credit Default Swaption

I have seen contracts on Asset Swap with termination feature, do you think an option on an asset swap is similar in nature to an option on a CDS?

Overnight Index Swap

<t>Right, agreed with Stochastix's comment, but does everyone agree with Monk's idea about convexity adjustment for OIS? To me, OIS is a fractal representation of a normal IRS. E.g. Normal 1M Libor Vs 1Year Fixed One year IRS, it does not require any convexity adjustment (for e.g. that suggested by ...

bermudan swaption

<t>Sorry, I do not understand. If the HW "tree" is constructed as a function of in-the-moneyness of the individually exercisable swaptions, wouldn't we have to build a tree for every deal we have? How would it be possible to perform a bankwide VaR for instance which includes all financial derivative...
