A key disadvantage of trading with CJS is that its services are limited to Hong Kong residents, which restricts access for international traders. The registration process also requires a bank account within Hong Kong, making it difficult for non-residents to trade. Although CJS offers competitive commission rates, the broker charges additional fees for services such as stock settlement, physical share withdrawals, and bank remittances. Furthermore, international traders may face limitations in accessing "cjs investments" and other services that are primarily tailored to the Hong Kong market.
