This study shows how correlated information consumption (CIC) of retail investors relates to comovement in stock market outcomes. We construct clusters of stocks with CIC by employing network analysis on Google co-search data. We predict significant comovement in returns and liquidity of stocks...

Estimation of the covariance matrix of asset returns is crucial to portfolio construction. As suggested by economic … theories, the correlation structure among assets differs between emerging markets and developed countries. It is therefore … imperative to make rigorous statistical inference on correlation matrix equality between the two groups of countries. However, if …
