Abstract
The goal of this paper is to investigate the forecasting ability of the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH). We estimate the DCC’s forecasting ability relative to unconditional volatility in three equity-based crashes: the S&L Crisis, the Dot-Com Boom/Crash, and the recent Credit Crisis. The assets we use are the S&P 500 index, 10-Year US Treasury bonds, Moody’s A Industrial bonds, and the Dollar/Yen exchange rate. Our results suggest that the choice of asset pair may be a determining factor in the forecasting ability of the DCC-GARCH model.

I. Introduction
Many of today’s key financial applications, including asset pricing, capital allocation, risk management, and portfolio hedging, are heavily dependent on accurate estimates and well-founded forecasts of asset return volatility and correlation between assets. Although volatility and correlation forecasting are both important, however, existing literature has dealt more closely with the performance of volatility models – only very recently has the issue of correlation estimation and forecasting begun to receive extensive investigation and analysis. The goal of this paper is to extend research that has been undertaken regarding the forecasting ability of one specific correlation model, the Dynamic

Research Objectives - 3 - 1.3. Research Approach and Scope - 3 - 1.4. Layout of the Report - 4 - 1. Introduction 2.1. Research Background Volatility is an important concept in finance. Volatility modelling and forecasting finds usage in several core financial operations, for instance – many asset-pricing models use volatility as an estimation parameter for simple risk; several famous option pricing formulas such as Black-Scholes use volatility; volatility estimates and forecasts are crucial for portfolio management and also in hedging risk. Because of the importance of volatility, as can be seen from the examples above, the interest in modelling and forecasting volatility has increased many-fold in recent times, with a special emphasis on forecasting. There are several types of techniques available for forecasting volatility, with extraordinary diversity of procedure such as the Autoregressive Moving Average (ARMA) models, Autoregressive Conditional Heteroscedasticity (ARCH) models, Stochastic Volatility (SV) models, regime switching and threshold models. (Xiao and Aydemir, 2007:1) A broad division between the techniques is based on primary assumptions of constant variance i.e. homoscedastic e.g. AMA models, or non-constant variance i.e. heteroscedastic or...

Lombardi† Francesco Ravazzolo‡ July 11, 2013 Abstract In the recent years several commentators hinted at an increase of the correlation between equity and commodity prices, and blamed investment in commodity-related products for this. First, this paper investigates such claims by looking at various measures of correlation. Next, we assess what are the implications of higher correlations between oil and equity prices for asset allocation. We develop a time-varying Bayesian Dynamic Conditional Correlation model for volatilities and correlations and find that joint modelling commodity and equity prices produces more accurate point and density forecasts, which lead to substantial benefits in portfolio...
