The use of stable distributions was motivated by the fact that traditional normality assumptions are not appropriate for the daily stock returns. Four selected series, two stock indices and two individual industrial returns, were examined. Estimates for the characteristic exponent parameter α were obtained. Following the estimation of the exponent parameter α, serial-dependence was studied by fitting autoregressive models, using two different minimization criteria.
