Unlike A shares, Hong Kong stocks and US stocks are expensive to trade. They encourage long-term investment. At the same time, brokers (they are investment banks) make money as intermediaries, that is, the tertiary industry, so both remittance and transaction costs are high. For example, the transaction fee for subscription of new shares is 100 Hong Kong dollars, which is not high, but there is a minimum fee, such as 100 Hong Kong dollars. Running a business will definitely take up employees' time. Labor time is money, so it costs a lot. As Hong Kong stocks receive Hong Kong dollars, the US dollar as a US stock is more valuable.

US stock accounts are mainly opened by online brokers.

For Hong Kong stocks, if you don't need special and complicated services, you can open an account in an investment bank, which can be used all over the country. If you need margin service and futures service, you need to open an account with a professional brokerage firm. Cai Yao and Credit Suisse in Hong Kong are very famous, and many mainland companies have set up subsidiaries in Hong Kong, such as China Merchants Securities (Hong Kong). As for whether you can open a Hong Kong account in China Merchants Securities Agency, you have to ask yourself.
