Do you want to invest in the US market in the simplest way? US large-cap index ETFs are your best choice.
Data shows that over a 10-year period, nearly 90% of professional fund managers underperform the index.
Smart “lazy investors” have long turned to these 5 star ETFs: VOO, IVV, SPY, VTI, QQQ. They are synonymous with steady profits, but each has different focuses and advantages.

These three ETFs are the most popular choices for investing in US large-cap indexes. They act like mirrors, faithfully reflecting the pulse of the US economy.
First, you need to understand that the core objective of SPY, VOO, and IVV is exactly the same: tracking the Standard & Poor’s 500 Index (S&P 500). This means that when you buy any one of them, you are effectively investing in about 500 top US listed companies, including Apple, Microsoft, Amazon, and others, all at once.
They come from the world’s three top asset management companies:
SPY: State Street Global AdvisorsVOO: VanguardIVV: BlackRockAlthough their goals are the same, their detailed differences determine which one is more suitable for you. These differences are mainly reflected in fees, scale, and liquidity.
Tip: The expense ratio is the annual management fee deducted from your investment. Even small differences can have a huge impact under long-term compounding.
Let’s compare their core data through a clear table:
| Metric | SPY | VOO | IVV |
|---|---|---|---|
| Issuer | State Street Global Advisors | Vanguard | BlackRock |
| Expense Ratio | 0.09% | 0.03% | 0.03% |
| Assets Under Management (AUM) | Approx. $418B | Approx. $323B | Approx. $336B |
| Average Daily Volume | Approx. 80 million shares | Approx. 7.4 million shares | Approx. 7.6 million shares |
From the table, you can see that SPY’s trading volume far leads, being more than 10 times that of VOO or IVV. This gives SPY extremely small bid-ask spreads, resulting in higher trading execution efficiency. However, its expense ratio is also three times that of the other two.
After understanding the differences, the choice becomes simple. Your investment strategy determines the final answer.
Once you have determined the ETF that best suits you, you can easily purchase it through platforms like Biyapay that support international investing and start your wealth growth journey.
In addition to the three giants focused on the S&P 500, there are two highly distinctive US large-cap index ETFs worth your attention: VTI and QQQ. They offer different perspectives for investing in the US market.
If you want to “buy the entire US stock market” with one ETF, then VTI (Vanguard Total Stock Market ETF) is your ultimate answer.
It tracks the CRSP US Total Market Index, with coverage far exceeding the S&P 500. VTI includes nearly 4,000 companies, from giants to newly emerging small companies, truly achieving comprehensive investment in the US stock market. Its expense ratio is also as low as 0.03%, the same as VOO.
Although it has broad coverage,
VTI's holdings are still dominated by large-cap stocks. This means its performance is highly similar to the S&P 500 but adds exposure to mid- and small-cap companies for you, capturing more growth potential.
| Market Cap Category | Percentage |
|---|---|
| Large-Cap (>$10bn) | 92.1% |
| Mid-Cap ($2-10bn) | 5.1% |
| Small-Cap (<$2bn) | 1.2% |
If you firmly believe that technology is the core driver of the future, then QQQ (Invesco QQQ Trust) is the growth engine tailor-made for you.
QQQ tracks the Nasdaq-100 Index, which includes the 100 largest non-financial companies listed on Nasdaq. Its stock selection criteria are very strict:
This makes QQQ's components highly concentrated in technology and innovation sectors.
| Symbol | Name | Weight Percentage |
|---|---|---|
| NVDA | NVIDIA Corporation | 9.37% |
| AAPL | Apple Inc. | 8.76% |
| MSFT | Microsoft Corporation | 7.51% |
| AVGO | Broadcom Inc. | 6.23% |
| AMZN | Amazon.com, Inc. | 5.14% |
Now, how should you choose among these ETFs?
VTI means pursuing ultimate diversification. Choosing VOO or IVV means focusing more on the core blue-chip stocks in the market. For beginners, both are excellent starting points.QQQ is more aggressive. Historical data shows its returns significantly outperform the S&P 500, but with greater volatility.| Metric | QQQ | SPY (Representing S&P 500) |
|---|---|---|
| Past 10-Year Annualized Average Return | 19.37% | 14.53% |
Allocating a portion of funds (e.g., 20%) from stable ETFs like VOO or VTI to QQQ can effectively increase your portfolio’s growth potential. However, you must also be aware that this makes your portfolio more concentrated in tech stocks and potentially subject to greater market volatility. Once you have decided on your portfolio, you can use a convenient platform like Biyapay to buy these ETFs in one stop and start your investment plan.

You may wonder why investment masters like Warren Buffett strongly recommend index investing. There are four core advantages behind this, which together form the solid foundation of “lazy investing.”
When you buy a single stock, your wealth is tightly tied to that company’s fate. But buying an S&P 500 ETF means diversifying your funds across about 500 top US companies.
This ultimate diversification provides powerful protection. Even if one company encounters difficulties or goes bankrupt, the impact on your overall portfolio is negligible. This is what the investment world often calls a “free lunch”, allowing you to effectively eliminate non-systematic risks associated with individual companies without extra cost.
Costs are the invisible killer eroding your investment returns. Actively managed funds need to pay high research and trading fees to outperform the market, which ultimately you bear.
Let’s see how big the fee gap is:
| Fund Type | Average Annual Expense Ratio |
|---|---|
| Actively Managed Large-Cap Funds | 1.10% |
| VOO / IVV / VTI | 0.03% |
A fee gap exceeding 1% becomes a huge amount under long-term compounding. Choosing low-cost index ETFs means you start ahead by a large margin.
Investment markets always fluctuate. Looking back at history, even the powerful US large-cap indexes have experienced severe shocks, such as over 55% declines during the 2008 financial crisis.
However, history also proves the market’s strong resilience. After crises, the market always recovers and reaches new highs. More importantly, if you extend the investment horizon, the probability of positive returns greatly increases.
Data shows that over the past 80+ years, the S&P 500 Index has achieved positive returns in every 10-year investment period.
This means that as long as you stick to long-term holding, time is your most reliable friend.
Another major appeal of index investing is its simplicity and transparency.
Now, you clearly understand the positioning of these 5 star ETFs:
For most “lazy investors” seeking stable returns, starting with a low-cost US large-cap index ETF (like VOO or IVV) and sticking to regular long-term investments is an excellent strategy.
Take action now! Based on your investment goals, choose the ETF that suits you best, take the first step in investing, and let your wealth grow steadily.
The investment threshold is very low. Many platforms support fractional shares, meaning you can start investing with just tens of dollars. You don’t have to buy a whole share at once.
Yes, the companies held by these ETFs pay dividends. You will regularly receive these dividends and can choose to reinvest them to achieve compound growth in your wealth.
For long-term investors, regularly investing a fixed amount is a good strategy. You can choose to invest monthly or quarterly, which averages your purchase cost and reduces the impact of market volatility.
Yes. ETFs like VOO or VTI already include hundreds or even thousands of companies. For most investors, holding one such ETF achieves excellent risk diversification.
