Using the next-day and next-week returns of stocks in the Korean market, we examine the association of option volume ratios - i.e. the option-to-stock (O/S) ratio, which is the total volume of put options and call options scaled by total underlying equity volume, and the put-call (P/C) ratio,...

We use trade-level data to examine the role of actively managed funds (AMFs) in earnings news dissemination. We find AMFs are drawn to, and participate disproportionately more in, earnings announcements (EAs) that include bundled managerial guidance. When the two pieces of news are directionally...

Background Traditional asset pricing models face challenges from financial anomalies, prompting exploration through behavioural finance theory. This study analyses the nuanced relationship between individual investor sentiment and key stock market variables. Objectives To assess the impact of...

We analyze investors' motives for trading on international stock markets and investigate whether evidence for these motives is robust when time-varying market volatility, changes between calm and turbulent periods, and existence of international financial spillovers are controlled for. Applying...

Utilising unique shareholding data for Australian equities we examine whether the high volume return premium (‘HVRP') is associated with changes in investor recognition as has been posited in various empirical studies. We confirm the existence of the premium in Australia as stocks which...

The phenomenon of high-volume return premium is generally attributed to the visibility hypothesis proposed by Gervais et al (2001) based on the theoretical framework of Miller (1977) and Merton's (1987)'s investor recognition hypothesis. However, no existing empirical study has directly tested...

Divergence in investor beliefs is an important driver of the negative relation between option trading volume and future stock returns. We find a strong negative relation between disagreement-based option trades and future stock returns, and this relation is markedly amplified when the underlying...

Utilising unique shareholding data for Australian equities we examine whether the high volume return premium (‘HVRP') is associated with changes in investor recognition as has been posited in various empirical studies. We confirm the existence of the premium in Australia as stocks which...

Employing asset-pricing models over the period 2012 to 2017, this study examines whether a search attention index (SAI) explains the variation in the weekly excess return of stocks. The study finds that the estimated abnormal return of a portfolio based on search intensity is significantly high...

We propose a new measure of investor disagreement based on thirty-nine factors from the return-predicting anomaly literature. Consistent with theoretical work on volume, we show that a one standard deviation change in anomaly-based disagreement is associated with a 16.7% higher turnover in the...
