The 1st Frontier Forum for Digital Technology and Finance

Abstract:
This study explores the problem of search heterogeneity from the time dimension and finds that the search from Monday to Friday is quite different from the search on Saturday and Sunday, and the search on Saturday and Sunday has a stronger association with stock trading and proposed a new search index accordingly. Empirical findings reveal the root cause of the problem that using search volume to represent attention only applies to small companies but not too large companies, addressing the issue that large S&P 500 stocks in research in this area are not significant to online searches.
