NETWORK MODELS in FINANCE

An insightful exploration of the theory and application of networks as applied to investment management

Network Models in Finance: Expanding the Tools for Portfolio and Risk Management is a singularly incisive and unique discussion of networks and graph theory as applied to the financial and investment markets. Researchers and authors Gueorgui Konstantinov and Frank Fabozzi walk you through a comprehensive overview of networks in investment management, providing deep insight into their implementation in portfolio and risk management.

You'll discover how to construct diversified and risk-optimized portfolios by linking the price and return movements of different asset classes and factors. You'll also find out how to better manage risk by properly understanding systematic, counterparty, and systemic risk, and by monitoring changes in the financial system that may indicate a coming financial crisis.

Network Models in Finance delivers practical examples of a wide variety of financial data that can be used to visualize, describe, and investigate markets in an entirely new way, and explains the interactions and causal relationships that operate within a network-based framework.

This book is a must-read for investors, asset managers, and other finance practitioners with an interest in a largely underexplored area of investing.

In Network Models in Finance: Expanding the Tools for Portfolio and Risk Management, a team of celebrated investment and finance educators and practitioners delivers a startlingly insightful and one-of-a-kind discussion of networks in investment management. Guided throughout by contemporary graph theory, the book explains how to identify and measure various types of networks and their characteristics in portfolio and risk management.

You'll learn to construct diversified portfolios with reduced risk exposure by understanding the link between price and return movements of different asset classes and factors. You'll also discover how to perform better risk management by understanding systematic, systemic, and counterparty risk and by monitoring changes in the financial system that indicate an incipient or potential financial crisis.

Network Models in Finance adopts a thoroughly "practitioner--first" approach. It provides practical examples of broad financial data to show the impressive possibilities available to those who wish to visualize, describe, and investigate markets in an entirely new way. It also demonstrates the interactions, causal relationships, and optimizations within network-based frameworks and their direct applications to the financial markets.

Finally, the authors walk you through a variety of algorithms enhanced by tested code that you can implement immediately and use on your own datasets.
