Want to invest in global leaders such as Apple (AAPL) and NVIDIA (NVDA) and share in their growth, but unsure how to get started in Hong Kong? Faced with a wide range of brokerage firms and US stock trading app recommendations, are you worried about high fees and complicated account opening procedures? In fact, buying US stocks in Hong Kong has become very simple. This article compiles the latest and most comprehensive 2026 US stock account comparison, covering platform fee summaries, account opening tutorials, and guidance on choosing the investment platform that suits you best, helping you take your first step into US stock investing with ease!
While Hong Kong investors are familiar with the local market, allocating part of your capital to US stocks is an important strategy for diversifying risk and seeking higher returns. For Hong Kong investors, buying US stocks offers the following unmatched advantages:
The US stock market brings together some of the most innovative and influential companies in the world. Whether technology giants such as Google (GOOGL) and Microsoft (MSFT), consumer leaders like Coca-Cola (KO) and Starbucks (SBUX), or future-oriented electric vehicle companies such as Tesla (TSLA), you can become a shareholder by purchasing their stocks and directly participate in and benefit from the growth of these world-class enterprises. This is an opportunity that a single regional market can hardly provide.
The US stock market is the largest and most liquid stock market in the world. Massive daily trading volume means relatively narrower bid-ask spreads, allowing investors to execute trades more easily and quickly at their desired prices. In addition, the US Securities and Exchange Commission (SEC) imposes strict regulations on listed companies. Financial reporting and major disclosures are subject to high transparency requirements, providing relatively strong protection for retail investors.
Beyond individual stocks, the US market offers an extremely wide range of investment tools. You can trade index ETFs such as SPY, which tracks the S&P 500, and QQQ, which tracks the Nasdaq 100, enabling diversified investment with a single trade. There are also sector ETFs, bond ETFs, gold ETFs, and more to meet various asset allocation needs. For advanced investors, derivatives such as options and futures are also available.

In addition to the newer online broker apps mentioned above, many Hong Kong investors also consider using traditional banks, such as HSBC and Citibank, to trade US stocks. So how should you choose between the two?
In summary, if you trade frequently, are cost-sensitive, and seek a better trading experience, online brokers are definitely the superior choice.
After reviewing the US stock account comparison above, have you chosen your preferred platform? Regardless of which one you select, the online account opening process is generally similar and can usually be completed within 15 minutes. It is very simple.
Before starting the online application, prepare electronic copies (either photos or scans) of the following documents:
Using a popular brokerage app as an example, the general process is as follows:
After successfully opening your account, the final step is to deposit funds and begin trading. Hong Kong brokers generally support the following deposit methods:
💡 Currency Exchange Tip: US stock trading requires US dollars. You may convert Hong Kong dollars to US dollars at your bank before transferring, or transfer Hong Kong dollars directly into your brokerage account and convert within the brokerage app. In general, online brokers offer more competitive exchange rates than traditional banks, with smaller spreads, helping you save on currency conversion costs.
A: Good question! Hong Kong investors buying US stocks generally follow the principle of “two exemptions and one obligation”. There is no capital gains tax (meaning the price difference earned from selling stocks is not subject to tax) and no interest tax. However, a 30 percent dividend withholding tax applies. For example, if the US stock you hold distributes a 100 US dollar dividend, you will actually receive 70 US dollars.
The W-8BEN form (formally known as the Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting) is a declaration that you are a “non-US tax resident”, allowing you to enjoy exemption from capital gains tax. This form is usually signed electronically during account opening and is valid for three years. Brokers will remind you to renew it before expiration.
A: The entry threshold for buying US stocks is much lower than you might think. The trading unit for US stocks is one share, so you can purchase just one share of Apple. For high-priced stocks such as Amazon (AMZN), one share may cost over a thousand US dollars. Fortunately, many brokers (such as Futu and IBKR) offer “fractional share” trading, meaning you can invest 100 US dollars or even less to purchase 0.01 shares. This significantly lowers the entry barrier and is very suitable for beginners with limited capital or those who prefer regular investment plans.
A: This depends on your needs. If you prioritize convenience and prefer to manage everything within a single banking app, and do not mind paying higher fees, a bank may be an option. However, if you are an active investor seeking lower trading costs, more professional trading tools, and richer market information, online brokerage apps offer an overwhelmingly superior choice in terms of fees, functionality, and user experience.
A: The regular trading hours of the US stock market correspond to Hong Kong time and vary between daylight saving and standard time. During daylight saving time (approximately March to November) trading hours are 9:30 pm to 4:00 am Hong Kong time. During standard time (approximately November to March), trading hours shift one hour later to 10:30 pm to 5:00 am. In addition, many brokers offer pre-market and after-hours trading sessions, but these periods generally have lower trading volume and higher price volatility.
A: In addition to normal market price volatility risk, investing in US stocks involves two additional key risks. The first is currency risk, since US stocks are denominated in US dollars, and fluctuations in the USD to HKD exchange rate will affect your final return. The second is policy risk. Federal Reserve interest rate policies and government regulatory policies on various industries can have significant impacts on the stock market. Therefore, conducting thorough research and diversifying investments are very important. For detailed tax information, you may refer to official documents from the Internal Revenue Service (IRS).
Overall, buying US stocks in Hong Kong is much simpler and more convenient than many people imagine. With the development of major online brokers, trading costs continue to decline while platform features become increasingly powerful. Choosing a low-cost, secure, and fully functional US stock trading app is the first step toward successful investing. We hope this detailed US stock account comparison, fee analysis, and account opening guide helps you make the most informed decision. Remember, after selecting the right tools, continuous learning and research remain the key to long-term success in the US stock market.
