GARCH-based Volatility Forecasts for Market Volatility Indices
نویسندگان
چکیده
Volatility forecasting is one of the main issues in the financial econometrics literature. Volatility measures may be derived from statistical models for conditional variance, or from option prices. In recent times, indices have been suggested which summarize the implied volatility of widely traded market index options. One such index is the so-called VXN, an average of 30-day ahead implied volatilities of the options written on the NASDAQ–100 Index. In this paper we show how forecasts obtained with traditional GARCH–type models can be used to forecast the volatility index VXN.

The use of GARCH models to characterize crude oil price volatility is widely observed in the empirical literature. In this paper the efficiency of six univariate GARCH models and two methods of estimation the parameters for forecasting oil price volatility are examined and the best method for forecasting crude oil price volatility of Brent market is determined. All the examined models in this p...
متن کاملVolatility forecasts and the at-the-money implied volatility: a multi-components ARCH approach and its relation with market models
For a given time horizon ∆T , this article explores the relationship between the realized volatility (the volatility that will occur between t and t + ∆T ), the implied volatility (corresponding to at-the-money option with expiry at t+∆T ), and several forecasts for the volatility build from multi-scales linear ARCH processes. The forecasts are derived from the process equations, and the parame...

متن کاملForecasting stock market volatility conditional on macroeconomic conditions
This paper presents a GARCH type volatility model with a time-varying unconditional volatility which is a function of macroeconomic information. It is an extension of the SPLINE GARCH model proposed by Engle and Rangel (2005). The advantage of the model proposed in this paper is that the macroeconomic information available (and/or forecasts) is used in the parameter estimation process. Based on...
متن کاملVolatility Forecasts in Financial Time Series with HMM-GARCH Models
Nowadays many researchers use GARCH models to generate volatility forecasts. However, it is well known that volatility persistence, as indicated by the sum of the two parameters G1 and A1[1], in GARCH models is usually too high. Since volatility forecasts in GARCH models are based on these two parameters, this may lead to poor volatility forecasts. It has long been argued that this high persist...
