Using a Markov regime switching model, this article presents evidence on the well-known January effect on stock returns. The specification allows a distinction to be drawn between two regimes, one with high volatility and other with low volatility. We obtain a time-varying January effect that...

We study three aspects of the Russian stock market – factors influencing stock returns, integration of the stock market with world .financial markets, and market efficiency – from 1995 to present, putting emphasis on how these evolved over time. We .find many highly unstable relationships,...

Implications of nonlinearity, nonstationarity and misspecification are considered from a forecasting perspective. My model allows for small departures from the martingale difference sequence hypothesis by including a nonlinear component, formulated as a general, integrable transformation of the...

Evidence suggests that rational, periodically collapsing speculative bubbles may be pervasive in stock markets globally, but there is no research that considers them at the individual stock level. In this study we develop and test an empirical asset pricing model that allows for speculative...

This research explores the risk associated with the stocks prices in the seventeen selected companies that are listed in Indian BSE (100) National as well as portfolios of investment that are constructed from these seventeen companies employed. Additionally, for considering the possibility of...

This paper contributes to the understanding of the non-linear causal linkage between investors’ sentiment dynamics and stock returns for the US economy. Employing the sentiment index developed by Baker and Wurgler [Baker, M., Wurgler, J., 2007. Investor sentiment in the stock market. Journal...

This paper contributes to the understanding of the non-linear causal linkage between investors' sentiment dynamics and stock returns for the US economy. Employing the sentiment index developed by Baker and Wurgler (J. Econ. Perspect. 16: 129-151, 2007) and within a non-linear causality...
