According to a report by Reuters, a US police investigation into an allegation of rape against CEO Richard Liu has hit the e-commerce giant's stock, with the case exposing the risks posed by his iron grip on management and the lack of other leaders to challenge him. Last week, Liu, who owns about 16 percent of’s stock, was arrested and then released without charge in the US city of Minneapolis. In the two days of trade since Liu's arrest, has already lost $7.2 billion dollars, or 16 percent of its total market value, amid fears that the case will turn customers away from its website.
