You can start trading US stocks by opening an investment account with banks or international brokers in Hong Kong. In the Hong Kong stock market, the minimum trading unit is “one lot”, which may equal to 100 shares, 500 shares, etc., depending on the stock price. However, in the US stocks market, you can buy ‘one share’. Once your account is open, you can choose from a list of popular US shares such as Amazon, Facebook, Apple and Google. If you are not a resident of the US, you won’t be charged on dividends from the US shares you buy.
