CITICS＇s net capital rose to about 5 billion yuan, much higher than any other competitor. This teaching case aims to demonstrate how a company gains first-mover advantage as being the first company to go public in an industry, how its competitors respond by changing their strategies after the IPO, and consequently, how a series of relevant events influence the competition. This case offers important implications for understanding the competitive dynamics of a securities company in China.展开更多
