AbstractPurpose- The research aims to propose a scalable multivariate non-Gaussian model for VaR and volatility estimation and analyze its efficiency(in appropriately taking into account fat tails, and asymmetry for VaR estimation) as compared to traditional Gaussian approaches used for VaR estimation and portfolio construction. Financial distributions generally tend to portray asymmetry, fat tails or a mixture of distributions, which are captured by the discussed model that involves incorporating the Pareto distribution, skewed- t distributionThe study also intends to demonstrate that this results in portfolios that are having more utility. (Utility: How much excess return was generated for each unit of risk taken by the portfolio and also generating a portfolio with higher economic growth)alternative approaches including mean-variance. The utility can be leveraged by efficiently selecting(maximizing the utility defined above) the portfolio assets and their weights. This research also investigates the correlation across stock market indices of 6 Asia-Pacific countries and uses VaR and variance as the risk measures for the analysis.Findings-The authors successfully concluded that the model proposed in the paper estimates VaR more accurately than the traditional model. Also, our proposed model tends to outperform the literature model in portfolio construction by producing asset weights more efficiently.Design/Methodology/Approach- This research uses a GSEV strategy that comprises a univariate EGARCH approach for calculating stochastic volatility and the leverage effect. The Generalized Pareto distribution captures asymmetry and heavy tails in the GARCH residuals (GPD). The skewed-t copula is used to describe asymmetric tail dependence. Originality/value- The value added is to depict how the non-Gaussian model proposed by the authors includes the exponential GARCH (EGARCH) technique, Generalized Pareto distribution, skewed-t copula, and mixed distributions consideration gives VaR prediction and portfolio asset weights values more accurately than the traditional model.

Download Artificial Intelligence in Asset Management Book in PDF, Epub and Kindle
Artificial intelligence (AI) has grown in presence in asset management and has revolutionized the sector in many ways. It has improved portfolio management, trading, and risk management practices by increasing efficiency, accuracy, and compliance. In particular, AI techniques help construct portfolios based on more accurate risk and return forecasts and more complex constraints. Trading algorithms use AI to devise novel trading signals and execute trades with lower transaction costs. AI also improves risk modeling and forecasting by generating insights from new data sources. Finally, robo-advisors owe a large part of their success to AI techniques. Yet the use of AI can also create new risks and challenges, such as those resulting from model opacity, complexity, and reliance on data integrity.

Download Understanding and Managing Model Risk Book in PDF, Epub and Kindle
A guide to the validation and risk management of quantitative models used for pricing and hedging Whereas the majority of quantitative finance books focus on mathematics and risk management books focus on regulatory aspects, this book addresses the elements missed by this literature--the risks of the models themselves. This book starts from regulatory issues, but translates them into practical suggestions to reduce the likelihood of model losses, basing model risk and validation on market experience and on a wide range of real-world examples, with a high level of detail and precise operative indications.

Download Multi-Asset Risk Modeling Book in PDF, Epub and Kindle
Multi-Asset Risk Modeling describes, in a single volume, the latest and most advanced risk modeling techniques for equities, debt, fixed income, futures and derivatives, commodities, and foreign exchange, as well as advanced algorithmic and electronic risk management. Beginning with the fundamentals of risk mathematics and quantitative risk analysis, the book moves on to discuss the laws in standard models that contributed to the 2008 financial crisis and talks about current and future banking regulation. Importantly, it also explores algorithmic trading, which currently receives sparse attention in the literature. By giving coherent recommendations about which statistical models to use for which asset class, this book makes a real contribution to the sciences of portfolio management and risk management. Covers all asset classes Provides mathematical theoretical explanations of risk as well as practical examples with empirical data Includes sections on equity risk modeling, futures and derivatives, credit markets, foreign exchange, and commodities
