The high-volume return premium and changes in investor recognition

摘要

The phenomenon ofhigh-volume return premiumis generally attributed to thevisibility hypothesisproposed by Gervais et al. (2001) based on the theoretical framework of Miller (1977) and Merton's (1987) investor recognition hypothesis. However, no existing empirical study has directly tested thevisibility hypothesisdue to the lack of high-frequency shareholding data. In this paper, we utilize the unique daily shareholding data for stocks listed on the Australian Stock Exchange to directly test this hypothesis by examining the relationship between the high-volume return premium and changes in investor recognition. We find that high-volume shocks do attract more investor attention and increase the investor base on the date of, and following, the shocks. This provides direct empirical evidence in support of the visibility explanation for the high-volume return premium. We also find that institutional and individual investors attend to different kinds of stocks; stocks attracting more institutional (individual) investors outperform (underperform) subsequent the volume shocks and exhibit a higher (lower) high-volume return premium. Our findings shed new light on thevisibility hypothesisby showing that recognition/attention from institutional or individual investor is also crucial in determining the extent of the high-volume return premium and may help to reconcile the existing mixed empirical evidence across international markets.
