Summary

News Analytics in Finance will be a landmark publication bringing together the latest models and applications of News Analytics for risk management and trading.It will be split into three sections. Firstly, the book will introduce news analytics and their applications to finance, focusing in particular on trading and risk management. It will then move on to analyse the range of models that can be used in trading and risk management functions, explaining how these models work, the behavioural and mathematical underpinnings, and how they can benefit trading and risk management systems, and will finally provide a directory of products and services for the practitioner who wants to incorporate these systems into his or her platform. The book will call upon the expertise of academics and practitioners who have developed these models and will be supported by one of the leading providers of news analytics software and machine readable news Ravenpack.

Author Biography

Gautam Mitra (London, UK) is an internationally renowned research scientist in the field of computational optimisation and modelling. He has developed a world class research group in his area of specialisation with researchers from Europe, UK, USA and Asia. He has published three books and over one hundred refereed research articles. He was Head of the Department of Mathematical Sciences, Brunel University between 1990 and 2001. In 2001 he established CARISMA: The Centre for the Analysis of Risk and Optimisation Modelling Applications. CARISMA specialises in the research of risk and optimisation and their combined paradigm in decision modelling. Professor Mitra is also a Director of UNICOM Seminars and OptiRisk Systems; OptiRisk specialises in the research and development of optimisation and financial analytics tools.

Leela Mitra (London, UK) is a Quantitative Analyst at OptiRisk Systems. Dr Mitra joined OptiRisk System as a Quantitative Analyst in 2004. She received her PhD in Operational Research on the topic of "Scenario generation for asset allocation models" from CARISMA, Brunel University. Topics included "mixed" scenario sets for investment decisions with downside risk, pricing and evaluating a bond portfolio using a regime switching Markov model and desirable properties for scenario generation. She has a first class BA (Joint Honours) degree in Mathematics and Philosophy from King's College (University of London). Prior to joining OptiRisk, Leela worked in the pensions industry as an actuarial consultant for Mercer HR and subsequently with Jardine Lloyd Thomson. She is part qualified as an actuary.
