Abstract

PurposeThe author investigates whether investors’ online information demand measured by Google search query and the changes in the numbers of Wikipedia page view can explain and predict stock return, trading volume and volatility dynamics of companies listed on the Nigerian Stock Exchange.Design/methodology/approachThe multiple regression model which encompasses both the univariate and multivariate regression framework was employed as the research methodology. As part of our pre-analysis, we test for multicollinearity and applied the Wu/Hausman specification test to detect whether endogeneity exist in the regression model.FindingsWe provide novel and robust evidence that Google searches neither explain the contemporaneous nor predict stock return, trading volume and volatility dynamics. Similarly, results also indicate that trading volume and volatility dynamics have no relationship with changes in the numbers of Wikipedia pages view related to stock activities.Originality/valueThis study opens new strand of empirical literature of “investors' attention” in the context of African stock markets as empirical evidence. No evidence from previous studies on investors' attention exist, whether in Google search query or Wikipedia page view, with respect to African stock markets, particularly the Nigerian stock market. This study seeks to bridge these knowledge gaps by examining these relations.

Highlights

  • Attention is a key aspect of our visual experience closely relates to perception (Zagoruyko and Komodakis, 2019)

  • We find that Google searches neither correlate with contemporaneous nor predict stock return, trading volume and volatility dynamics

  • In this paper, we examined empirically whether investors’ online search intensity measured by Google search volume (GSV) and Wikipedia page views influences the stock return, trading volume and the volatility dynamics of the Nigerian stock market

Summary

Introduction

Attention is a key aspect of our visual experience closely relates to perception (Zagoruyko and Komodakis, 2019). We need to pay attention in order to adequately perceive our surroundings. Attention is crucial but difficult to measure directly, previous studies could not provide direct measurement. For example; Takeda and Yamazaki (2006), Kim and Meschke (2011) used the appearances on TV programs as a proxy for investors’ attention. The paper by Antweiler and Frank (2004) reports that Internet stock messages posted on Yahoo! Finance and raging bull can help predict stock market volatility, JEL Classification — C22, C52, G12 © Osarumwense Osabuohien-Irabor.
