Using a novel proxy of investors' speculative demand constructed from online search interest in “concept stocks”, we examine how speculative demand affects the returns and trading volume of Chinese stock indices. We find that returns and trading volume increase with the contemporaneous...

We develop a dynamic model of belief dispersion with a continuum of investors differing in beliefs. The model is tractable and qualitatively matches many of the empirical regularities in a stock price, its mean return, volatility, and trading volume. We find that the stock price is convex in...

We examine the effects of limited investor attention on stock returns by using Google search volume index to measure investor attention. We also investigate whether national culture and market development have any role in this relationship. We find that the impact of investor attention on stock...

Extensive research has revealed that alphabetical name ordering tends to provide an advantage to those positioned in the beginning of an alphabetical listing. This paper is the first to explore the implications of this alphabetic bias in financial markets. We find that U.S. stocks that appear...

We apply the sequential unit root tests of Phillips et al. (2015) for mildly explosive processes to identify and date-stamp bubbles in the emerging and frontier African stock markets. We find periods of explosive behavior in the price–dividend ratio in several markets which is indicative of...

We investigate the distribution of relative returns (RR) among agents who possess varying levels of information in an artificial stock market (ASM). We demonstrate the existence of the J-curve in this market. In contrast to previous studies, the agents in possession of the least information are...

How do investors perceive dependence between stock returns? And how does their perception of dependence affect investments and stock prices? We show experimentally that investors understand differences in dependence, but not in terms of correlation. Participants invest as if applying a simple...
