This paper develops both univariate and multivariate distributions based on Gram-Charlier and Edgeworth expansions, attempting to ensure non negativity by exploiting the orthogonal properties of the Hermite polynomials. The article motivates the problems underlying some specifications (in...

We analyze the relationship between dividends and insiders' transactions in an attempt to determine whether insider trading modifies the interpretation of any signal sent by the increase/decrease in dividend payments. The aim is to determine whether insider transactions are as good signal as...

This paper introduces the Edgeworth-Sargan distribution on measuring Value-at-Risk of portfolios. The flexible parametric representation of this density makes it capable of improving the density fits (especially at the tails) and permits a straightforward method of percentile computation....

The current research examines the capacity of the Edgeworth-Sargan density on forecasting market crashes. Focusing on the 1987 stock market crash the performance of this distribution is compared to the Student's t concluding that the latter overestimates the risk. In contrast, and due to its...
