Investing in US Major Market Indices: Why Choose Index ETFs First?

Buffett’s advice sounds great, but you might ask: What exactly is an index ETF? Why is it so suitable for beginners? Let’s explain it to you in the simplest way.

What is an Index ETF?

You can think of an index ETF as a pre-packaged “stock shopping basket.”

You do not need to personally select stocks like Apple, Microsoft, or Amazon but directly buy a basket. This basket already contains a series of company stocks according to specific rules. For example, an ETF tracking the S&P 500 Index is equivalent to a basket holding stocks of 500 largest US listed companies. Buying one share of such an ETF makes you a micro-shareholder in all 500 companies at once.

Simple Comparison: ETF vs. Traditional Mutual Fund ETFs generally have advantages in trading flexibility and investment threshold.

Feature	Index ETF	Traditional Mutual Fund
Minimum Investment	As low as the price of one share	Usually has higher initial investment threshold
Trading Method	Trades like stocks, anytime during trading hours	Only once daily at end-of-day net asset value
Transparency	Usually discloses holdings daily, very transparent	Usually discloses quarterly or monthly

Why is it Most Friendly for Beginners?

Choosing index ETFs as a starting point mainly has three core advantages, making your investing more reassuring and effortless.

1. Automatic Risk Diversification You no longer need to worry about a single company “stepping on a landmine” leading to total loss. Because your investment is already automatically diversified across hundreds of companies and multiple industries. For example, the VOO ETF holds over 500 stocks, covering all major sectors like technology, finance, health, etc., greatly reducing individual stock risk.
2. Enjoy Long-Term Market Growth Investing in index ETFs, you are betting not on a single company’s future but on the long-term growth of the entire US economy. Historical data shows that despite short-term fluctuations, the US major market exhibits steady growth trends long-term. You just need to hold to share in the overall market’s growth dividends.
3. Low Investment Threshold and Time-Saving You do not need to spend a lot of time researching complex financial statements and market dynamics. After choosing a good major index-tracking ETF, the rest is just persistent investment. At the same time, buying ETFs is as simple as buying stocks, with a minimum of just one share, very flexible startup funds, extremely friendly to beginners.

How to Choose Your First Index ETF?

You already understand the advantages of index ETFs; now comes the most critical step: choosing your first ETF. Facing codes like VOO, QQQ, VTI, you might feel confused. Don’t worry; this choice is simpler than you imagine.

Understanding Mainstream US Major Market Indices

First, you need to understand what these ETFs track. They each correspond to different “stock baskets,” representing different aspects of the US market.

• S&P 500 Index: This is the most famous index, including 500 largest US companies by market cap. Investing in it is equivalent to investing in leading US economic companies.
• Nasdaq-100 Index: This index focuses on 100 largest non-financial companies listed on Nasdaq. It is dominated by tech and innovative companies like Amazon, Google, etc., often seen as a growth representative.
• Total Stock Market Index: As the name suggests, it attempts to cover the entire US stock market, including nearly 4,000 stocks, from giants to small companies.

VOO vs. QQQ vs. VTI: Core ETF Comparison

There are many ETFs tracking these indices on the market, but for beginners, focusing on the following most popular ones is sufficient. They are huge in scale and very actively traded.

Choosing Based on Fees and Goals

Your choice should be based on two core factors: fees and your investment goals.

Fees are the only certain “negative return” in investing Do not underestimate a 0.1% fee difference. Assuming 7% annualized returns, over 30 years, just paying an extra 0.1% fee annually could reduce your final returns by thousands or even tens of thousands of dollars. Choosing low-fee ETFs is key to long-term investment success.

Now, you can ask yourself a question: Do you want to steadily follow the entire US major market, or are you more bullish on the future of tech stocks?

• Pursuing Stability and Diversification (Recommended for Beginners): Choose VOO or VTI. They have extremely low fees and highest risk diversification, perfect cornerstones for building long-term portfolios.
• Bullish on Tech and Growth: If you believe the tech sector will continue to lead and can tolerate greater market volatility, consider including QQQ as part of your portfolio. Historical data shows QQQ provided higher returns over the past decade but with greater risk.

For the vast majority of beginners, the simplest answer is: Start with VOO or VTI; you won’t go wrong.

You have chosen the ETF; now the final step—actual operation. This step is where many beginners hesitate, but as long as you follow the guide, you will find it much simpler than imagined. Let’s complete it step by step.

How to Choose an Account Opening Channel?

To buy US ETFs, you need a broker account. For investors in mainland China, there are mainly two ways:

1. Directly Open an Overseas Broker Account: For example, through emerging internet broker platforms like Biyapay.
2. Through Mainland Chinese Broker Sub-Account Services: That is, delegate a mainland Chinese broker to place orders overseas for you.

What is the difference between these two methods? A table lets you understand:

Advice for Beginners If you pursue lower costs and richer choices, directly choosing a reputable, convenient overseas broker is better. Platforms like Biyapay have optimized account opening processes and trading experiences for the mobile internet era, very suitable for beginner entry.

Account Opening and Deposit Process

Taking choosing an overseas broker like Biyapay as an example, the entire process can be divided into two steps: online account opening and depositing funds.

Step One: Prepare Account Opening Materials

The account opening process is completely online; you need to prepare clear photos or scans of the following documents in advance:

• Identity Proof Document: This document must include your name, date of birth, and photo. Usually can be:
  • Passport
  • ID card
• Proof of Address Document: This document needs to clearly show your name and address, usually required to be recent (e.g., within 12 months). Acceptable documents include:
  • Bank statements
  • Utility bills
  • Valid lease agreement
  • Government-issued letters (e.g., tax bills)

Tip: Please ensure the identity proof and address proof are two different documents. For example, if you use an ID card as identity proof, you need to use a bank statement or other document for address proof.

In addition to documents, during online application, you need to fill in some personal information, such as occupation, annual income, investment goals, etc. Please fill truthfully; this is a standard regulatory requirement.

Step Two: Complete Deposit

After account approval, you can deposit funds to prepare for trading. For mainland China investors depositing to overseas broker accounts, the most common method is wire transfer.

• Wire Transfer: You need to wire funds through your bank (recommended using a licensed Hong Kong bank account supporting overseas remittances) to the broker’s designated receiving account. Funds usually take 1-2 business days to arrive.
• ACH Transfer: If you have a US bank account, you can use ACH for electronic transfer, usually lower or even free fees.

Fee Reminder Broker platforms (like Biyapay) usually do not charge deposit fees, but during wire transfer, your sending bank and intermediary banks may charge certain fees. It is recommended to consult your bank for specific fee standards before operating.

Setting Up Regular Investments (DCA)

This is the essence of the “dollar-cost averaging” strategy—automating investments to eliminate emotional interference. Dollar-cost averaging (DCA) is a “lazy investor method”; you only need to set it once, and the system will automatically buy the specified ETF for you with a fixed amount at fixed intervals each month.

Is DCA Really Better?

You might wonder: Is lump-sum investing all funds at once better than periodic dollar-cost averaging (DCA)?

• From Historical Returns: Research shows that due to the long-term upward trend of the US stock market, about two-thirds of the time, lump-sum investing outperforms DCA. Because your funds enter the market earlier, enjoying longer compound growth.
• From Risk and Psychology: DCA’s biggest advantage is reducing risk and smoothing emotions. It perfectly avoids the nightmare of “investing all at the market peak.” During market declines, your fixed investment amount can buy more shares, lowering your average holding cost. For ordinary investors unable to predict the market and with stable monthly cash flow, DCA is an excellent tool for building investment discipline and smoothing market volatility.

For beginners, DCA is undoubtedly the most steady and worry-free way to start the investment journey.

How to Set Up Automatic Investments?

Most modern broker platforms (like Biyapay) provide automatic investment functions. General setup steps are as follows:

1. Log into your broker account and find the “recurring investment” or “automatic investment” function entrance.
2. Select the ETF you want to invest in regularly, for example, enter code VOO.
3. Set Investment Plan:
   • Investment Amount: For example, invest 500 USD monthly.
   • Investment Frequency: Choose “once monthly”.
   • Execution Date: Choose a date you like, such as the 15th of each month.
4. Confirm and Activate Plan.

After setup, you become a “hands-off investor.” Regardless of market ups and downs, the system will disciplinedly execute your investment plan. All you need to do is focus on life and work, then patiently wait for time’s roses.

Long-Term Holding: A Few Things You Need to Know

You have successfully taken the first step, but investing is a marathon, not a sprint. Long-term holding sounds simple, but sticking to it requires discipline and knowledge. The following are a few important things you need to know; they will help you face the future more calmly.

Key Fees You Must Understand

In addition to the previously mentioned ETF management fees, during long-term holding, you will encounter two other fees:

• CurrencyExchangeFees: When converting funds to USD for investment, the broker platform charges a fee. This fee may be calculated as a percentage of the transaction value (e.g., 0.5%) or a small spread added to the exchange rate.
• DividendWithholding Tax: When your held ETF distributes dividends, this money needs tax withheld first. According to US tax rules, as a non-US resident investor, dividends you receive usually require 30% withholding tax. The W-8 BEN form you submit during account opening is used to confirm your non-US resident status and enjoy this tax benefit.

What to Do During Market Volatility?

The market will not always rise; declines are inevitable in the investment process. When your account shows losses, panic is the biggest enemy. History tells us that the market has strong recovery ability.

Golden Rules for Facing Volatility

1. Avoid Panic Selling: Recognize that market declines are usually temporary and stick to your long-term plan.
2. Stick to Your Investments: During market declines, the same amount buys more shares, lowering your average cost.
3. Do Not Try to Predict the Bottom: No one can accurately predict the market; the best strategy is to maintain discipline.

Remember, you are investing in the long-term future of the entire US economy, not short-term market emotions.

The Magic of Dividend Reinvestment

Many ETFs regularly distribute dividends paid by constituent companies to you in cash, like small rewards from your investment. For example, QQQ’s annual dividend yield is not high, but it is still extra income.

You can choose to withdraw this money, but a smarter approach is to enable the “Dividend Reinvestment Plan” (DRIP).

What is DRIP? This is a completely automated function. Once enabled, the broker automatically uses your received dividends to buy more shares of the same ETF, even if only fractional shares. This process is usually commission-free.

This simple setting can create the miracle of compounding. Your dividends buy new assets, and these new assets will generate new dividends in the future. Over time, your assets will snowball, growing larger and larger. You just need to find this option in your broker account and enable it to easily enjoy the magic of “money making money.”

Congratulations! You have mastered all the knowledge to start your US major market index investment journey. The action path is very clear:

1. Choose an index ETF you favor with low fees (like VOO).
2. Complete account opening and deposit through a broker.
3. Set up monthly automatic investments.
4. Stay patient and hold long-term.
