We study the impact of parameter uncertainty on the expected utility of a multiperiod investor subject to quadratic transaction costs. We characterize the utility loss associated with ignoring parameter uncertainty, and show that it is equal to the product between the single-period utility loss...

The beta dispersion, which is the spread of betas on a stock market, can be interpreted as a measure of market vulnerability. This study examines the economic idea of the beta dispersion and its application as a market return predictor. Based on the empirical beta dispersion observed in the US...

Rebalancing alpha is the excess return of a fixed-weight portfolio, which is regularly rebalanced, over its buy-and-hold counterpart. Two kinds of effects, both results of portfolio rebalancing, contribute to rebalancing alpha. The first is a volatility effect that arises from randomness of...

An intensive and still growing body of research focuses on estimating a portfolio’s Value-at-Risk.Depending on both the degree of non-linearity of the instruments comprised in the portfolio and thewillingness to make restrictive assumptions on the underlying statistical distributions, a...

This paper deals with the estimation of portfolio returns and Value at Risk (VaR), by using a class of Gaussian mixture distributions. Asset return distributions are frequently assumed to follow a normal or log normal distribution. It also can follow Brownian motion or Geometric Brownian motion...

This paper provides a comprehensive analysis on stock return predictability in Santiago Stock Exchange from January 2007 to January 2016 by employing portfolio method. In the risk-related predictors, we found no statistically significant predictive power of beta, total volatility, and...

This study aims to analyze and test empirically the influence of corporate financial performance against systematic risk on stocks. The analysis technique used is multiple linear regression. The results showed that the financial performance did not significantly affect the systematic risk of the...

This study employs the Vector Autoregressive-Generalized Autoregressive Conditional Heteroskedasticity (VAR-AGARCH) model to examine both return and volatility spillovers from the USA (developed) and China (Emerging) towards eight emerging Asian stock markets during the full sample period, the...
