I just realized something quite interesting: if you leave your money in a Vietnamese bank earning only 5-6% per year, then you’re missing out on a big opportunity. The S&P 500 index has grown by more than 10% per year over the past 30 years, and in 2026 the US market is in a fairly attractive phase. The question is: why not step into this market?

Investing in US stocks is no longer just for the wealthy or financial experts. With just 100 USD and a phone, you can participate fully from Vietnam. But before you jump in, you need to understand how the mechanism works and the potential traps.

The US market has 2 biggest trading exchanges: NYSE and Nasdaq. To keep track of what’s going on, you only need to pay attention to 3 main indices: S&P 500 (500 large-cap companies), Nasdaq 100 (tech and AI-focused), and Dow Jones (30 Blue-chip groups). The important difference is that the US market has no daily trading limit like VN-Index (7%), so profit opportunities are higher—but risks are also greater if you don’t have a plan.

Looking at the 2026 outlook, the market is recovering strongly thanks to two leading industry groups. First is AI technology and semiconductors—these areas have moved into real-world applications, generating actual revenue instead of just promises. Second is the financial sector, where banks benefit from a stable interest-rate environment. In addition, the FED has just sent out a softer signal on interest rates, triggering a “Risk-on” mindset among investors worldwide.

If you want to invest in US stocks, you have 3 main options. First is owning stocks directly through an international broker—this gives you real ownership and dividends, but the KYC process is complicated. Second is trading CFDs with leverage—more flexible and with smaller capital, but you don’t own the actual stocks. Third is buying ETFs through a domestic fintech app—this is the easiest, but the management fees are higher.

In practice, the US market’s trading hours are offset from Vietnam’s time zone, which is actually an advantage for people who work during the day. In summer, you can trade from 20:30 to 03:00 the next morning (Vietnam time). Outside regular hours, there are also pre-market and after-hours, but volatility is very strong during these periods because earnings are usually released then.

One important point: you must use Stop Loss (cutting losses) as a mandatory habit. Since there’s no trading floor/ceiling, a stock can drop by 50% overnight if the company has problems. Also, when the market is highly volatile, always use Limit Order instead of Market Order to avoid slippage.

When it comes to capital management strategy, the 2% rule is non-negotiable: never risk more than 2% of your total account on a single trade. For long-term investing, the DCA (Dollar-Cost Averaging) method—buying regularly every month regardless of whether prices go up or down—is the most effective way to beat the market over 10+ years.

For the leading sectors in 2026, Big Tech is still king, but focus on AI application software instead of hardware, which has already run too hot. In addition, Healthcare and green energy are also good opportunities to accumulate for the long term because these are trends that cannot be reversed.

Compared with SJC gold, investing in US stocks has significantly higher growth potential. If you factor in the average depreciation of VND versus USD of about 2-3% per year, the actual performance of holding USD-denominated assets is even higher. A pragmatic conclusion: gold is for storing money; US stocks are for multiplying it.

But you also have to acknowledge there are traps you need to avoid. During major news releases (Non-farm Payroll, CPI, FOMC), the Spread can increase up to 10 times the normal level. If you do Scalping at this time, you’ll lose even as soon as you enter the trade. Also, be careful about FOMO psychology. If you see a stock drop 10% and want to jump in, wait for a confirmed reversal signal before deciding.

There is one legal point to pay attention to: according to Vietnam’s State Bank regulations, citizens are not allowed to transfer foreign currency abroad on their own for financial investment without a license. Most individual investors currently deposit/withdraw through international exchanges via intermediary payment gateways or via domestic bank transfers. If that exchange is a scam or collapses, you will have to bear 100% of the risk with no protection from Vietnamese law. Therefore, choosing a Broker with reputable licenses from FCA (UK), ASIC (Australia), or SEC (US) is the only protective shield. When withdrawing large amounts back to your domestic bank account, banks have the right to temporarily hold funds to require explanation of the source of income, so always keep a record of your transactions on the exchange.

Frequently asked questions: Can I invest with only 50-100 USD? The answer is yes. Current platforms allow you to buy Fractional Shares—0.1 or 0.01 of an Apple or Microsoft share—without needing a few hundred USD. If you’re a beginner with limited capital, prioritize buying fractional stocks or ETFs instead of CFDs to avoid blowing up your account.

As for taxes, foreign investors will be subject to a 30% withholding tax on dividend income. When opening an account, the platform will ask you to fill out Form W-8BEN, and the platform will automatically deduct 30% before crediting the remaining amount to your account.

Finally, you can still trade even if you don’t know English, because all platforms have Vietnamese versions. However, knowing basic English is an advantage for reading the original financial reports from Bloomberg or Reuters more promptly.

Overall, investing in US stocks provides opportunities for superior returns, but it is not a gold mine for those who lack knowledge. The key to success is to start with a small amount of capital, strictly follow the 2% capital management rule, use Stop Loss as a mandatory habit, and always keep learning. Wall Street is waiting for you, but make sure you prepare thoroughly first.
