In this paper we discuss univariate and multivariate statistical properties of volatility with the aim of understanding … how these two aspects are interrelated. Specifically, we focus on the relationship between the cross-correlation among … stock's volatilities and the volatility clustering. Volatility clustering is related to the memory property of the …

We propose a comprehensive treatment of the leverage effect, i.e. the relationship between returns and volatility of a … estimating the volatility process without assuming any specific form of its behavior, we find the volatility to be long … detrended cross-correlation and the detrending moving-average cross-correlation coefficients and we find the standard leverage …

This paper introduces a new class of stochastic volatility models which allows for stochastic volatility of volatility … (SVV): Volatility modulated non-Gaussian Ornstein-Uhlenbeck (VMOU) processes. Various probabilistic properties of …

This paper examines time-varying stock price and volatility dynamics of constituent industry sector indices in the … of return during rises in aggregate stock market volatility. Finally, this paper identifies which industries exhibit the … highest degree of volatility persistence and how this impacts their respective beta estimates. It shows time-dependence in …

observed volatility of private equity returns is unrealistically low because the recorded returns of private equity are based … the observed volatility. As an alternative to observed volatility some investors have argued that private equity … volatility should be estimated as leveraged public equity volatility, because private equity companies are more highly levered …
