Abstract

Stable distribution, also known as Lévy stable distribution, which is a rich class of heavy-tailed distributions can capture asymmetry and heavy tails observed in financial data. In this paper, we fit an AR(1) process with α - stable innovations to the logarithms of volumes of Walmart stock traded daily on the New York Stock Exchange and estimate the TCE (Tail Conditional Expectation) risk measure.

Keywords

autoregressive process; Lévy stable distribution; risk measure
