dc.description.abstract | I assess the robustness to different periods and panel models of several findings
in the literature that uses Google search volume as an investor attention proxy. With
all S&P 500 stocks between 2004 and 2016, I confirm that weekly search volume
is persistent and increases are associated with high share turnover as well as
earnings announcements. When the CCEMG estimator of Pesaran (2006) is used, I
find evidence against Da et al. (2011) but consistent with Barber and Odean (2008).
Even for large stocks, surges in people’s attention predict positive abnormal returns
one week ahead, which reverse within one year. I conclude the literature should
adopt panel estimators more robust to the presence of both firm and time effects. | nb_NO |
