Resumen de Investor awareness and the long-term impact of FTSE 100 index redefinitions

Bryan Mase

• This study finds an asymmetric long-run abnormal return performance following stocks� inclusion in or deletion from the FTSE 100 Index. This asymmetry suggests that investors� awareness of stocks is influenced by index changes. These results extend those documented by Chen et al. (2004) for the S&P 500.
