Disclaimer: I have no interest connection with any company mentioned in this article. This article is purely my personal experience and opinions and is for reference only.

If you want to invest in US stocks, here are the ways:

  • The first way: open an account with a Taiwanese brokerage, and then specify that you want to open the function of sub-brokerage trading of US stocks.
  • The second way: open an account directly with an online brokerage in the United States.
  • The third type: open an account directly with fintech companies in the United States.


The most convenient way for Taiwanese investors to participate in U.S. stocks is to go to the Taiwan brokerage where you opened an account, and ask for the function of sub-brokerage for you. By the way, according to the data at the end of 2020, more than 2 million Taiwanese have opened sub-brokerage accounts with Taiwanese brokerage firms to invest in overseas stock markets, and there has been an accelerated growth in recent years.

The following is a comparison table between Taiwanese sub-brokerage and U.S. online brokerages:

As stated in sections 1-6 of my book “The Rules of Super Growth Stocks Investing”, online brokerages in the United States are now extremely competitive. Below is a comparison table of the two most famous online brokerages in the United States. Sources: Charles Schwab, Interactive Brokers.

As mentioned earlier, the competition among online brokerages in the United States is very fierce, and transaction commissions have almost all been cut to zero, with few exceptions. Interactive Brokers (ticker: IBKR) in the above table is one of the few well-known brokerages that still charge handling fees among the online brokerages. Except that the handling fee is almost zero, the big difference between them is the minimum account balance for opening an account, that is, the minimum amount of stocks plus cash in the account.

The competition among new fintech firms in the United States is fiercer than that of online securities firms in the United States, and stock trading is usually only a small part of their business. The trading commissions of new financial technology companies in the United States are almost zero, and most of them do not have a minimum account balance requirement. In order to attract you to open an account, some give away stocks as incentive. For example, in 2021, SoFi (ticker: SOFI) will open an account and give away a share of Coca-Cola (ticker: KO) stock.
