Multi-Factor Models and Signal Processing Techniques: Application to Quantitative Finance

With recent outbreaks of multiple large-scale financial crises, amplified by interconnected risk sources, a new paradigm of fundmanagement has emerged. This new paradigm leverages"embedded" quantitative processes and methods toprovide more transparent, adaptive, reliable and easily implemented"risk assessment-based" practices.
This book surveys the most widely used factor models employedwithin the field of financial asset pricing. Through the concreteapplication of evaluating risks in the hedge fund industry, theauthors demonstrate that signal processing techniques are aninteresting alternative to the selection of factors (bothfundamentals and statistical factors) and can provide moreefficient estimation procedures, based on lq regularized Kalmanfiltering for instance.
With numerous illustrative examples from stock markets, this bookmeets the needs of both finance practitioners and graduate studentsin science, econometrics and finance.
