This is an
astonishingly good book that goes well beyond its title. Sure, it covers the
management of portfolios of credits from both an asset management and an
asset-liability standpoint, but there is more—much more. Offering a
sophisticated mix of market practice and finance theory, the book delves into
the markets, instruments, conventions, pricing, and portfolio management of
credit-sensitive instruments.
The book is
suitable for sophisticated buy-side professionals, but I also recommend it for
sell-side analysts or systems professionals—indeed, any sell-side professional
who doesn't already deal with credit products on a day-to-day basis.
What do I like
about the book? First, I like how comprehensive it is, covering basics like
instruments, compounding conventions and market participants before taking on
more advanced topics.
Second, I like the
authors' practical familiarity with market practice. These guys didn't learn
from a textbook. As just one example, consider their treatment of credit
spreads. Many books discuss credit spreads in a general sort of way, but these
authors identify three standard conventions for quoting credit spreads: yield
spread, z spread and asset-swap spread. They define them, explain how each is
calculated and identify strengths and weaknesses of each.
Finally, I like
the way the authors communicate sophisticated material in a manner that is
accessible to readers with only marginal quantitative skills. For example, they
offer an excellent treatment of structural, intensity and transition-matrix
pricing models for single-name credits. To make discussions accessible, binomial
models take the place of stochastic calculus. But it is surprising how
sophisticated the discussions remain. They include the most accessible
explanation of the pricing kernel I have ever seen. Formulas are used sparingly,
but they appear at all the right times.

What does the book
cover? Markets, participants, fixed income conventions, credit analysis, credit
spreads, single-name pricing models, multi-name pricing models, trading,
portfolio management, performance analysis, accounting and Basel II. Standard
fixed income instruments and credit derivatives are the primary focus. CDOs
receive little mention.
The authors
are German, so expect German Bunds to be discussed more often than US
Treasuries. For US readers, this will be more of an international flavor
than a distraction. The chapter on accounting looks at IAS instead of GAAP.
References are
cited sparingly, but the right references are cited. A lot of recent research
that readers may not be familiar with is mentioned.
The book is
accessible to beginners, but I think more experienced readers will benefit more.
They will understand the relevance of topics and how they relate to one another
in ways beginners will not. The book is not advanced, but it goes well beyond
the basics. Buy side readers be forewarned: this book gives you more than enough
information to be dangerous.
Because it covers
so many topics so well, it will be useful to different audiences in different
ways. It is a book on credit markets, a book on credit risk modeling, a book on
credit financial engineering and a book on credit portfolio management. Rarely
is a book simultaneously so accessible and so sophisticated. I highly recommend
it. [December 13, 2006]
