The S&P 500 is the most-watched stock market index on earth. For everyday investors, the easiest way to own a slice of it is through an S&P 500 ETF (Exchange-Traded Fund) like Vanguard's VOO or State Street's SPY.
In June 2026, the investing landscape hit a historic milestone. Vanguard's S&P 500 ETF (VOO) became the first exchange-traded fund in history to cross $1 trillion in assets under management (AUM).
This guide breaks down how the S&P 500 works, why VOO reached this historic scale, and how beginners can start investing in top funds like VOO and SPY with zero commission from just $1 using the Nemo.money app.
What Is the S&P 500 Index?
The S&P 500 (Standard & Poor's 500) is a stock market index that tracks 500 of the largest publicly traded companies in the United States. It covers roughly 80% of the available US market capitalization, making it the ultimate health gauge for the US economy.
- Market Representation: When analysts say "the US market is up," they are almost always referring to the performance of the S&P 500.
- Instant Diversification: Instead of risking your money on a single company, the index spreads your investment across America's biggest businesses.
- Core Holdings: It includes market leaders across all sectors, such as NVIDIA, Apple, Microsoft, Amazon, Alphabet, and Broadcom.
- Current Market Context: As of mid-June 2026, the S&P 500 index is trading near record highs around the 7,500 level, driven by strong corporate earnings and artificial intelligence tailwinds.
What Is VOO? (Vanguard S&P 500 ETF)
You cannot buy a stock market index directly because it is simply a list of companies. To invest in it, you must buy a fund that tracks it.
VOO is the ticker symbol for the Vanguard S&P 500 ETF. Launched by Vanguard in 2010, VOO is a passive investment fund that holds the exact same 500 companies as the S&P 500 index, in the exact same proportions. When the index goes up or down, VOO mirrors that movement almost perfectly.

VOO vs SPY vs IVV: What is the Difference?
When looking for S&P 500 ETFs, investors frequently ask about the "Big Three": VOO (Vanguard), SPY (SPDR S&P 500 ETF Trust), and IVV (iShares Core S&P 500 ETF). All three track the exact same index, but they differ in cost, structure, and target audience:
- VOO (Vanguard): Features an ultra-low 0.03% expense ratio. It is the most cost-efficient option for long-term, buy-and-hold retail investors.
- IVV (iShares): Also features a competitive 0.03% expense ratio and offers high liquidity, backed by BlackRock.
- SPY (State Street): The oldest ETF in the world, carrying a 0.09% expense ratio. While slightly more expensive for long-term savers, its massive trading volume makes it the preferred tool for institutional investors and short-term day traders.
Simplified Cost Comparison Example: VOO vs SPY
If you invest $1,000, VOO costs you just $0.30 (30 cents) a year in management fees, while SPY costs $0.90 (90 cents) a year. If your portfolio grows to $10,000, you will pay $3 a year for VOO versus $9 a year for SPY. While these amounts seem small, choosing the lower-fee option leaves more of your money in your account to compound and grow over time.
Is VOO a Good Investment for Beginners?
Yes, VOO is widely considered an excellent building block for beginners because it eliminates the need to pick individual stocks. However, index investing is not risk-free. Beginners must understand three critical factors:
- Market Volatility: VOO is 100% equity-based. If the US stock market drops, VOO drops with it. For instance, macroeconomic pressures like geopolitical tensions in the Middle East and energy price spikes caused notable market dips in Q1 2026.
- Top-Heavy Concentration: The S&P 500 is market-cap weighted. This means larger companies make up a larger percentage of the fund. Tech giants like NVIDIA, Microsoft, and Apple exert a massive influence on your returns.
- Geographic Risk: VOO only invests in US-registered corporations. It offers zero direct exposure to European, Asian, or emerging markets.
