This paper proposes and compares portfolio selection models under the assumption that the portfolios of returns follow a GARCH type process. We compute the price/return distribution at some future time approximating the GARCH process with... more
This paper studies time-varying market efficiency in twenty emerging and five developed equity markets for the period covering from January 2000 to June 2017 by using daily returns from MSCI indices and draws a comparison between emerging... more
The aim of this paper was to accurately and efficiently forecast from multivariate generalized autoregressive conditional heteroscedastic models. The Rotated Dynamic Conditional Correlation (RDCC) model with the Normal, Student’s-t and... more
The estimation of inflation volatility is important to Central Banks as it guides their policy initiatives for achieving and maintaining price stability. This paper employs three models from the Generalized Autoregressive Conditional... more

In European countries, the last decade has been characterized by a deregulation of power production and electricity became a commodity exchanged in proper markets. This resulted in an increasing interest of the scientific community on... more
The study aims to extend the GARCH type volatility models to their nonlinear TAR (Tong, 1990) and STAR-based (Terasvirta, 1994) counter parts where both the conditional mean and the conditional variance processes follow TAR and STAR... more
This study aims to highlight the importance of GARCH models in the volatility modeling and forecasting as a mechanism for crisis management and early warning. After presenting the theoretical background of the models have been applied at... more
The stock market is constantly changing with uncertainties. That's why the analysis of certain time series from the economic and financial world shows specific characteristics that are not theoretically taken into account in ARIMA... more
It is crucial to model, quantify and understand the variables and dynamics that underlie the well-known extreme behaviour of spot electricity prices in wholesale markets. We explicitly model the conditional volatility and skewness of... more
El presente Trabajo Fin de Master plantea como objetivo la aplicación práctica del modelo GARCH y distribuciones de colas anchas en el cálculo del riesgo de mercado, mediante metodología VeR Paramétrica, en una cartera de renta variable... more
This study is a comparative investigation in the field of GARCH estimation. Short and long term market risk components are estimated based on financial market indices of eight countries including members of the advanced G10 (United... more
L’obiettivo del progetto di tesi è quello di mostrare gli aspetti teorici necessari alla realizzazione di una piattaforma web-based di supporto agli investimenti finanziari, attraverso la messa a disposizione di una serie di strumenti... more
Volatility in financial markets, particularly stock exchange markets, is an important issue that concerns theorists and practitioners. Over the past 30 years, there has been a vast literature for modeling the temporal dependencies in... more
The aim of this chapter is to provide a detailed empirical example of autoregressive conditional heteroskedasticity (ARCH) model and selected generalized ARCH models. Before the ARCH/GARCH models are estimated, several calculations and... more
The aim and objective of this study is to model and forecast the stock index volatility of Shanghai and Shenzhen index. The volatility is estimated by employing three GARCH-type models standard GARCH, GJR-GARCH and the EGARCH. Their... more
This paper aims to measure the nature of volatility in the cryptocurrency market before and during Covid-19 pandemic period. To achieve this goal, the Wald test, Granger Causality and Generalized Autoregressive Conditional... more
This paper investigates volatility spillovers in the stock market in Japan during the COVID-19 pandemic by using GARCH family models. The empirical analysis is focused on the dynamics of the NIKKEI 225 stock market index during the sample... more
Options are instruments which have the special property of limiting the downside risk, while not limiting the upside potential, thus their use in hedging. The share of the options market in the Indian capital market has increased to 64%... more
This study introduces a state-of-the-art volatility forecasting method for container shipping freight rates. Over the last decade, the container shipping industry has become very unpredictable. The demolition of the shipping conferences... more
We proposed a strategic asset allocation framework in which forward-looking views on various fixed income asset-classes are developed on volatilities rather than returns. Such methodology rely on some powerful and practical tools such as... more
