Comparing The Predictive Performances of Value at Risk Estimation Methods-An Extreme Value Perspective

Year 2020, Volume: 1 Issue: 1, 1 - 9, 30.12.2020

Abstract

Various methodologies are developed to supervise and manage financial risks due to the risk management in the derivative market become highly important in the recent years in response to financial crisis. The Value at Risk (VaR) summarizes the worst loss over a target horizon with a given level of confidence. In 2008, extreme price fluctuations in the global financial disaster show that inefficiency of GARCH models whose main assumption is normality. Extreme value theory is a powerful and fairly robust framework that investigates the tail behavior of the distributions. The main objection of this paper is to compare performances of VaR estimations which are obtained by GARCH models and Extreme Value Theory (Generalized Pareto Distribution and Generalized Extreme Distribution) in process of 2008 global financial crisis by using secondly ISE30 index in between 02 January 2009 and 02 April 2012.

Riske Maruz Değer Tahmin Yöntemlerinde Fiyat Tahmini Performanslarının Uç Değer Yöntemi ile Karşılaştırılması

Abstract

Son yıllarda yaşanan finansal krizlere karşılık türev piyasalardaki risk yönetimi önem kazanmakla birlikte finansal riski denetlemek ve yönetmek için çeşitli yöntemler geliştirilmektedir. Riske maruz değer (RMD) verilen güven aralığında belirlenen zaman diliminde karşılaşılabilecek en büyük kaybı özetlemektedir. 2008 yılında, küresel finansal felakette görülen yüksek fiyat dalgalanmaları, temel varsayımı normal dağılım olan GARCH modellerinin yetersizliğini göstermiştir. Uç değerler yöntemi ise dağılımın kuyruk hareketlerini inceleyen güçlü ve oldukça sağlam bir yöntemdir. Bu çalışmanın temel amacı, 2008 küresel kriz sürecinde, 02 Ocak 2009 - 02 Nisan 2012 tarih aralığındaki ISE30 endeksi kullanılarak, GARCH modelleri ve Uç değerler yöntemi (Genelleştirilmiş Pareto Dağılımı, Genelleştirilmiş Uç Dağılımı) ile hesaplanan Riske Maruz Değer tahminlerinin karşılaştırılmasıdır.
