Then the firms are categorized into two groups based on four different shareholder structures to compare the capabilities of coping with the adverse external impact.
The empirical event studies have shown that firms with multiple product lines and belonging to groups doing business in China and South Eastern Asia areas performed better. In addition, groups of firms with higher proportion of shares held by the ten largest shareholders and by the domestic institute investors performed, while firms with higher proportion of shares held by foreign institute investors responded more rapidly than the rest of the four shareholder structures to the external shocks.
