The spirit of exotics, November 26, 2010
This review is from: Demystifying Exotic Products: Interest Rates, Equities and Foreign Exchange (The Wiley Finance Series) (Hardcover)
I have been working as vaildation quant (model review) for several years.
My very first assignment happened to be a validation of a PRDC. I got the product proposal from the FO together with some c++ code. Getting throgh the algebra ( Ito calculus, the description of Markov Functional and XCCY BGM for comparison, calibration ) went well. However, I missed the understanding of the product.
What motivated it? What are the assumptions on the economic side ?
Why does the PRDC swap look like, as it looks like ? How does it compare to XCCY swap ? Why do rthey use the term "funding" leg ?
Why the hell do we make our lives more complicated with the early exercise feature ? Why is it good for the customer ?
How does it look like with the FX options ?
All these terms seem to be pretty obvious for practicioners ( especially for desk quants and structurers ) but at that time ( early 2000 ) there existed no book from which the beginner could get these fundamental things, making you really undrestand the product. You did not want to seem like a fool by asking these pretty obvious things from the FO. So what I did I validated the product ( merely on the operation side ) and begin asking myself these pretty obvious questions. It took me about a year ( while working fulltime ) to figure out the answers myself.
If I had this book at disposal, life would have been much more easy. The book does not mention the models nor numerical methods. It concentrates on the basic financial principles. Explains you how the exotic structures ( triggers, callable products, TARN like products ) are used to enhance the investor's profit by taking extra risk. Explains you the economic motivations why it is profitable to take a CMS coupon bond, especially in the current situation, with low short rates and the assumption, that the rates will be growing in the future. Also analyses the exotic EQ products and lets us us know why the hell one would buy a Himalaya option.
I think, that these sorts of books were rare so far, since they concenrated mainly on Maths. No problem with that, but if you are lacking for understanding of the product, the Maths will not help you too long. And the product knowledge, you could get with several years of work experience and a lot of effort, suddenly stands here prepared in this book.
I recommend it to novice quants, especially on the model development / validation side, where the interaction with FO is more problematic and thus this practical knowledge is more hard to obtain.
