A large part of the current debate on US stock price behavior concentrates on the question of whether stock prices are driven by fundamentals or by non-fundamental factors. In this paper we put forward the hypothesis that a present value model with time-varying expected returns provides an...

This paper provides some new empirical evidence on the weekend effect (one of the best known anomalies in financial markets) in Ukrainian futures prices. The analysis uses various statistical techniques (average analysis, Student's t-test, dummy variables, and fractional integration) to test for...

This paper investigates how the stock market reacts to firm level liquidity shocks. We find that negative and persistent liquidity shocks not only lead to lower contemporaneous returns, but also predict negative returns for up to six months in the future. Long-short portfolios sorted on past...

We propose several multivariate variance ratio statistics. We derive the asymptotic distribution of the statistics and scalar functions thereof under the null hypothesis that returns are unpredictable after a constant mean adjustment (i.e., under the weak form Efficient Market Hypothesis). We do...

We find that aggregate net equity fund flows are strongly negatively correlated with changes in expected future stock market volatility as measured by the VIX. Implying that investor purchase decisions are primarily driven by returns and sale decisions by risk perceptions, we further find that...
