The behaviour of the distribution of stock returns is of fundamental importance in financial economics, in view of its direct bearing on the descriptive validity of any theoretical model. We analysed the behaviour of Japanese stock return distributions using the Pearson system of frequency...

The market portfolio is often used as a benchmark portfolio. Japanese equity market data however shows that the market portfolio is not efficient and furthermore not profitable. The empirical support for CAPM in the Japanese market is weak. Overall, Japanese investors experienced hard time,...

The aim of this study is to provide a comprehensive description of the dependence pattern of stock returns by studying a range of quantiles of the conditional return distribution using quantile autoregression. This enables us in particular to study the behavior of extreme quantiles associated...

Empirical evidence on the distributional characteristics of common stock returns indicates: (1) A power-law tail index close to three describes the behavior of the positive tail of the survivor function of returns (pr(r x) ~ x^-\alpha), a reflection of fat tails; (2) general linear and...
