Abstract

This paper test the factors explaining of cumulative abnormal returns. To this end, we examined a sample of 137 firms in 2007. We tested event study methodology to measure the cumulative abnormal returns. An event window spans from-10 days to 10 days. In our study, we considered an estimation period from -20 days to -10 days. For the dependent variable, and after the announcement date (date of the general meeting), we try to estimate the cumulative abnormal returns of 1 day, 2 days, 6 days and 8 days. The empirical results of the cross sectional model show that the market reacts negatively because of an increase in profitability, firm size and managerial ownership. The opposite effect is observed for leverage. However, the effect of spending on research and development is not statistically significant.
