Quantitative Modeling of
Derivative Securities
Introduction
This book originated in
lecture notes for the courses Mathematics of Finance I and //, which I have taught at the
Courant Institute since the fall of 1993. As the material evolved and the possibility of
writing a book became more real, I joined forces with Peter Laurence, of the University of
Rome, who provided the scholarship and technical expertise needed to develop these notes
and shape them into a coherent text. Quantitative Modeling of Derivative Securities is the
fruit of more than 2 years of close collaboration between us.
Our motivation for writing
this book can be traced to the early 1990s when there was an increasing interest on the
part of Wall Street firms in the so-called structured financial products or
"second-generation derivatives." At that time, it had become commonplace for
top-bracket investment banks to market new financial products with tailor-made payoffs.1
The capability of designing these new financial derivatives, to bring them to the market
and to manage their risk using financial engineering, is still seen as a competitive
advantage. Another important aspect of quantitative analysis that developed strongly in
the 1990s is the management of derivatives at the portfolio level using multifactor
models. This "aggregate" approach to risk-management went far beyond the
single-asset Black-Scholes model. For example, the 1990s saw U.S. dollar interest-rate
derivatives markets reach their maturity. Quantitative models of the term-structure of
interest rates until then the realm of econometricians and Fed watchers enabled Wall
Street traders to warehouse and manage thousands of derivatives simultaneously. Asset
pricing theory was a hammer that found its nail. This book is strongly influenced by the
following two aspects of modeling derivatives: (1) pricing new financial products and
measuring their market risk and (2) developing multifactor models that deal with several
underlying securities particularly in the realm of fixed-income derivatives.
This is a textbook on the
theory behind modeling derivatives and their risk-management. The more theoretical
portions of the book were drawn from several sources, among them Darrell Duffle's Dynamic
Asset Pricing Theory, which provides a superb road map to the financial markets and
asset-pricing, and the papers of Cox, Ingersoll, and Ross. Other sources included many
readings in quantitative models, our own research on option volatility and risk-management
and, last but not least, 2 years' experience in Wall Street: first at Banque Indosuez'
foreign-exchange options department and later at Morgan Stanley Dean Witter's Derivative
Products Group in the area of fixed-income derivatives.
