The Art of Credit Derivatives
Beschreibung
The Art of Credit Derivatives shows practitioners how toput a framework in place which will support the securitizationactivity. By showing the models that support this activityand linking them with very practical examples, the authors show whya mind-shift within the quant community is needed - a move fromsimple modeling to a more hands on mindset where the modelerunderstands the trading implicitly.
The book has been written in five parts, covering the modelingframework; single name corporate credit derivatives; multi namecorporate credit derivatives; asset backed securities and dynamiccredit portfolio management.
Coverage includes:
* groundbreaking solutions to the inherent risks associated withinvesting in securitization instruments
* how to use the standardized credit indices as the mostappropriate instruments in price discovery processes and why theseindices are the essential tools for short term credit portfoliomanagement
* why the dynamics of systemic correlation and the standardisedcredit indices are linked with leverage, and consequently theimplications for liquidity and solvability of financialinstitutions
* how Lévy processes and long term memory processes arerelated to the understanding of economic activity
* why regulatory capital should be portfolio dependant and how touse stress tests and scenario analysis to model this
* how to put structured products in a mark-to market-environment,increasing transparency for accounting and compliance.
This book will be invaluable reading for Credit Analysts,Quantitative Analysts, Credit Portfolio Managers, Academics andanyone interested in these complex yet important markets.
