We propose a model of “disposition extrapolators”—investors subject to both extrapolative beliefs and the disposition effect—to explain the sharp rise in prices and volume observed in historical financial bubbles. The model generates a novel mechanism for volume, and we test its...

Rational bubbles in stocks can cause increases in trading volume, even after accounting for their expansionary effect on output and consumption. Trading volume increases are not caused by speculation driven by differences in beliefs. Dividend-bearing assets used to transfer resources...

A predictable pattern of stock market return is the violation of the efficient market hypothesis (EMH). It is well studied and evident in financial literature that stock markets around the world have predictable patterns e.g. calendar effect, behavioural effect, and Religious festival effect....

Considerable theoretical and empirical evidence links price comovements with the behavior of retail investors. Nevertheless, when predicting stock return correlations, research has focused on the leverage effect. We propose a new model of realized covariances that allows exogenous predictors to...

In recent years, exchange-traded fund (ETF) markets have grown exponentially due to their rising popularity amongst retail investors with a preference for passive investments. However, the effect of this rising popularity on the performance of ETF markets remains understudied. Therefore, the...

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...

This research examines whether Google search volume index (GSVI), a proxy of investor attention, can predict the excess returns and abnormal trading volumes of TPEx 50 index constituents. It also explores the motive underlying GSVI based on positive or negative shocks to stock prices. The...
