Note(s): This table reports the time-series average of the cross-sectional mean of the quarterly changes of size-adjusted institutional ownership and the quarterly changes of size-adjusted number of institutional investors in the stock portfolios by market-to-book and its decomposed components, total pricing error (including firm-specific error and sector error) and value-to-book (Rhodes-Kropf et al., 2005). The row L – H reports the differences of the coefficients between low market-to-book (and mispricing and value-to-book components) and high market-to-book (and mispricing and value-to-book components) firms. The sample period is from 1982Q1 to 2015Q4 (136 quarters). t-statistics are reported in parentheses calculated with Newey and West (1987) robust standard errors. The lag is one quarter
