Volatility forecasts play a central role among equity risk measures. Besides traditional statistical models, modern … forecasting techniques, based on machine learning, can readily be employed when treating volatility as a univariate, daily time …-ahead volatility by using high-frequency data. We show that the dilated convolutional filters are ideally suited to extract relevant …

March 2020 packed 2 ½ years of normal U.S. stock market volatility into one month, making it the most volatile month on … respond to such volatility? In this article we explore four possible approaches, two long-term and two short-term in nature …. We give particular focus to Volatility Targeting and Momentum strategies, discussing the investor behavior that might …

middle-term asset volatility is used for determination of the size of opening position when buy signal is obtained from trend … following model. The strategy is named as timing-and-volatility strategy.Two ways of implementation of the timing-and-volatility … strategy are proposed: without use of leverage and with use of leverage.

We apply univariate GARCH models to construct a computationally simple filter for estimating the conditional correlation matrix of asset returns. The proposed Variance Implied Conditional Correlation (VICC) exploits the polarization result that links the correlation between two standardized...

For a weighted sum of asset returns that are independent and identically distributed (IID) up to variance, we derive expressions linking the distribution of variance across assets with higher-order portfolio moments, assuming these quantities are finite. In particular, we show concise...

We introduce a new framework for understanding portfolio diversification that provides a coherent basis for comparing methodologies and offers a new approach to portfolio construction. The primary argument is that measures of diversification based only on a covariance matrix are ambiguous...
