International Stock Trading Guide: How to Invest in US Stocks from Vietnam in 2025

In 2025, the US stock market remains an attractive choice for Vietnamese investors looking to expand their global portfolios. With over 6,300 listed stocks, this market is the largest playground in the world, home to tech giants like Apple, Amazon, Tesla, and numerous companies with strong growth potential. The market capitalization value of the US far exceeds that of other countries, creating countless opportunities for smart investors.

Why Invest in International Stocks - Specifically the US Market?

Diversity and Higher Yield Opportunities

Compared to the Vietnamese stock market, the US market offers a much more diverse collection of companies. The S&P 500 index – representing the US stock market – has increased by over 39% from May 2018 to now, while VNIndex has decreased by more than 9%. The Nasdaq index is even more impressive with a 64% increase, thanks to the explosive growth of tech stocks.

Leading companies like Facebook, Amazon, Apple, and Google are listed on the world’s largest exchanges, NYSE and NASDAQ. Investing in these names not only offers high profit opportunities but also allows you to participate in globally leading industries.

Risk Reduction Through Diversification

Focusing only on the Vietnamese market amid an economy under pressure from rising interest rates and VND depreciation is a risky strategy. Holding US stocks helps investors diversify risk and create a more balanced portfolio.

Two Main Ways to Invest in International Stocks from Vietnam

Since foreign individual investors cannot directly trade on NYSE and NASDAQ (require US citizenship), there are two main tools to access this market:

ETF - A Safe Gateway for Beginners

Exchange Traded Fund (ETF) functions as an investment fund mimicking stock indices, combining features of mutual funds and regular stocks.

Advantages of ETFs:

• Easy diversification with low costs
• No need for in-depth knowledge of individual stocks
• Limited market manipulation impact

Popular US index ETFs include: Vanguard S&P 500 ETF (VOO), SPDR S&P 500 ETF (SPY), iShares Core S&P 500 ETF (IVV).

CFD - Flexible Tool for Experienced Investors

Contract for Difference (CFD) allows you to trade individual stocks without actual ownership. You profit from price differences, whether stocks go up or down.

Advantages of CFDs:

• More flexible than ETFs, can short sell
• Higher leverage, up to 1:200 on some instruments
• After-hours trading and low costs
• Access from a single platform

Specific Steps to Start Trading

Step 1: Choose a reputable trading platform

Your broker plays a decisive role in your investment journey. Select companies regulated by international authorities such as ASIC, FCA, or equivalent.

Step 2: Learn about the market

Before investing real money, use a demo account (if available) to familiarize yourself with trading methods, understand price fluctuations, and analytical tools.

Step 3: Determine your capital

Start with a small amount you can afford to lose. If using leverage, keep it at a low level until you gain more confidence.

Step 4: Place your trades

Buy (long) when you expect prices to rise, or sell short (short) when you anticipate prices will fall.

Step 5: Manage your positions

Always set take profit and stop-loss points in advance. When using leverage, profits and losses are amplified, so continuous monitoring is essential.

NYSE and NASDAQ - The Two Largest Stock Exchanges in the World

NYSE (New York Stock Exchange)

Founded in 1792, NYSE is the oldest stock exchange in the US. Major, long-established, and stable US companies are listed here. As of 2022, daily trading volume reached 5 billion shares, with a market capitalization close to $24.6 trillion. NYSE operates from Monday to Friday, 9:30 AM to 4:00 PM (US time).

NASDAQ

Started in 1971 as the first electronic exchange, NASDAQ is the second-largest in market capitalization. It focuses heavily on technology companies and startups. Less strict listing requirements mean stocks here tend to be more speculative.

Three US Stock Indices You Should Know

S&P 500 - Representative of the Overall Market

Comprising 500 top companies, accounting for about 80% of the total US market value. The S&P 500 uses a market-cap weighted method, meaning each stock’s influence is proportional to its market cap. It reflects the overall market trend.

Dow Jones Industrial Average (DJIA) - Symbol of Major Companies

Consists of 30 of the largest and most influential companies, representing about 1/4 of the total US market value. DJIA uses a price-weighted system, so high-priced stocks have a greater impact. Known for its list of stable “blue-chip” companies that pay regular dividends.

NASDAQ Composite - Reflects the Tech Sector’s Strength

Includes all stocks traded on NASDAQ, mainly tech companies but also many other sectors. Contains both large-cap and small-cap stocks, reflecting trends in the tech industry and investor sentiment towards speculative stocks.

Preparing for Your International Stock Trading Journey

Build Stronger Knowledge

Regardless of the market you invest in, understanding that market thoroughly is essential for developing suitable strategies. Learn from reputable financial sources, monitor key economic indicators, and understand factors influencing stock prices.

Manage Your Investment Psychology

Stock markets can be highly volatile. Stay calm, follow your strategy, and avoid emotional decision-making.

Risks Always Exist

No trade guarantees 100% profit. Always prepare for the worst-case scenario and only trade with money you can afford to lose.
