HONG KONG (BLOOMBERG) - When shareholders get angry at management, they typically vote down executive pay packages or stage protests. In Hong Kong, they call in the thugs. In March, about 18 intruders tried to force their way into a shareholder meeting held by brokerage Convoy Global Holdings and assaulted company employees, the firm said. Eight men were arrested, according to police. Hong Kong is rare among developed markets for incidents of violence involving hired muscle at shareholder events. The closest parallel would be Japan in the 1980s and 1990s, when public company meetings were disrupted by yakuza gangsters demanding payoffs.
