Can we Improve Understanding of the Financial Market Dependencies in the Crisis by their Decomposition?

Barunik, Jozef - In: ACTA VSFS 7 (2013) 1, pp. 6-30

estimation to the time-frequency domain for the first time. Usage of wavelets allows us to decompose the correlation measures … new theoretical framework for the realized covariation estimation generalizing the current knowledge and bringing the … correlation as they have large impact on these measures. Our results have significant economic value as wrong assumption about the …

ASYMMETRIES IN CONDITIONAL MEAN AND VARIANCE: MODELLING STOCK RETURNS BY asMA-asQGARCH

Brännäs, Kurt; Gooijer, Jan G. de - Institutionen för Nationalekonomi, Umeå Universitet - 2000

The asymmetric moving average model (asMA) is extended to allow for asymmetric quadratic conditional heteroskedasticity (asQGARCH). The asymmetric parametrization of the conditional variance encompasses the quadratic GARCH model of Sentana (1995). We introduce a framework for testing asymmetries...

An Alternative Conditional Asymmetry Specification for Stock Returns

Brännäs, Kurt; Nordman, Niklas - Institutionen för Nationalekonomi, Umeå Universitet - 2001

The paper advances the log-generalized gamma distribution as a suitable generator of conditional skewness. Based on the NYSE composite daily returns an asMA-asQGARCH model along with skewness dynamics is estimated. The results indicate a skewness that varies between sizeable negative skewness...

Temporal Aggregation of the Returns of a Stock Index Series

Brännäs, Kurt - Institutionen för Nationalekonomi, Umeå Universitet - 2003

The effects of temporal aggregation on asymmetry properties and the kurtosis of returns based on the NYSE composite index are studied. There is less asymmetry in responses to shocks for weekly and monthly frequencies than for the daily frequency. Kurtosis is not smaller for the lower frequencies.

Volatility Forecasting: Downside Risk, Jumps and Leverage Effect

Audrino, Francesco; Hu, Yujia - School of Economics and Political Science, Universität … - 2011

We provide new empirical evidence on volatility forecasting in relation to asymmetries present in the dynamics of both return and volatility processes. Leverage and volatility feedback effects among continuous and jump components of the S&P500 price and volatility dynamics are examined using...

Modeling multivariate parametric densities of financial returns (in Russian)

Balaev, Alexey - In: Quantile (2011) 9, pp. 39-60

This paper compares several bivariate conditional density parameterizations for stock market returns in terms of in-sample fit and out-of-sample predictive ability for the whole conditional density. We consider Skew-Normal, Skew-Student, Skew-GED and Gram-Charlier densities. We focus on the...
