United States investors can purchase shares of companies listed on the Hong Kong Stock Exchange through several practical methods. Many major online brokerages in the US provide international trading desks or direct global market access, enabling retail investors to execute trades on foreign exchanges. Alternatively, many prominent Hong Kong corporations and Chinese enterprises trading in Hong Kong also maintain American Depositary Receipts that trade directly on major US exchanges like the New York Stock Exchange or NASDAQ, bypassing the need for a specialized foreign account.
