The effects of temporal aggregation on asymmetry properties and the kurtosis of returns based on the NYSE composite … frequency. Kurtosis is not smaller for the lower frequencies. …

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 and almost symmetry. The conditional variance and skewness measures are …
