Usually in financial textbooks and courses the theory of portfolio selection is taught in a strictly theoretical way …, given her preference curves and an efficient frontier. On the other hand, the Capital Asset Pricing Model (CAPM) is … practitioners conclude that those models are just inapplicable theory. This is the most rational behavior one can expect. What can …

The endogeneity of the efficient frontier in the mean-variance model of portfolio selection is commonly obscured in the portfolio selection literature and in widely used textbooks. The authors demonstrate this endogeneity and discuss the impact of parameter changes on the mean-variance efficient...

The Fama–French pricing model with dynamic factors (DFPM) extracted via the Kalman filter from the six size and book-to-market portfolios has a good performance in understanding stock returns. Using international stock market data, we find that the DFPM significantly improves the...

We investigate empirical properties of idiosyncratic volatility using cross-sections of stock returns in the standard framework of geometric Brownian motion price dynamics. Knowledge of the sign and magnitude of idiosyncratic volatility characteristics may help us better understand the role of...

We suggest a new measure of total ex-ante volatility (EAV) in stock returns, which includes traditional non-market (or idiosyncratic) risk and the unexpected component of market return. We find that the portfolio-level EAV measure exhibits strong predictive power for the cross-section of average...

This paper starts by unveiling a strong empirical regularity: multinational corporations exhibit higher stock market returns and earning yields than non-multinational firms. Within non-multinationals, exporters exhibit higher earning yields and returns than firms selling only in their domestic...
