Forecasting S&P 100 Volatility: The Incremental Information Content of Implied Volatilities and High Frequency Index Returns
TL;DR: In this paper, the information content of implied volatilities and intra-day returns is compared, in the context of forecasting index volatility over horizons from one to twenty days.
Journal ArticleDOI
Forecasting S&P 100 volatility: the incremental information content of implied volatilities and high frequency index returns
TL;DR: In this article, the information content of implied volatilities and intraday returns is compared in the context of forecasting index volatility over horizons from 1 to 20 days, and it is shown that the VIX index provides the most accurate forecasts for all forecast horizons and performance measures considered.
Journal ArticleDOI
Modelling S&P 100 volatility: the information content of stock returns
TL;DR: In this article, a detailed analysis of the daily volatility of the S&P 100 index from 1984 to 1998 shows that there is some incremental volatility information in the returns from the 100 shares that define the index, and this evidence is obtained from ARCH models that incorporate leverage effects, dummy variables for the 1987 crash and aggregate measures of stock return volatility.

Asymmetric and Crash Effects in Stock Volatility for the S&P 100 Index and its Constituents
TL;DR: In this article, the authors compared the volatility process of the S&P 100 index and all its constituent stocks after estimating ARCH models from ten years of daily returns, from 1983 to 1992, and concluded that the majority of stocks have a greater volatility response to negative returns than to positive returns and the asymmetry is higher for the index than for most stocks.
