This paper examines the hypothesis that both stock returns and volatility are asymmetric functions of past information derived from domestic and U.S. stock-market news. The results show the presence of negative autocorrelation, which is consistent with the dominance of positive-feedback trading...

Purpose – The purpose of this paper is to examine positive-feedback (PF) behavior and its relationship to momentum profitability and information uncertainty. Design/methodology/approach – Using the behavioral function of rational traders and feedback traders, the authors jointly estimate the...

This paper re-examines the performance of REITs, stocks, and fixed-income assets based on the preferences of risk-averse and risk-seeking investors using mean-variance and stochastic dominance approaches. Our findings indicate no first-order stochastic dominance and no arbitrage opportunity...

This paper employs weighted least squares to examine the risk-return relation by applying high-frequency data from four major stock indexes in the US market and finds some evidence in favor of a positive relation between the mean of the excess returns and expected risk. However, by using...

Evidence from this study suggests that investor sentiment and the peso problem play a significant role in explaining expectation errors, rejecting the unbiased expectation hypothesis (UEH). The deviation of the UEH for long-term rates is mainly attributable to expectation errors, whereas the...

This paper investigates statistical properties of high-frequency intraday stock returns across various frequencies. Both time series and panel data are utilized to explore the properties of probability distribution, dynamic conditional correlations, and scaling analysis in Dow Jones Industrial...
