VOO is an index fund — specifically, it tracks the S&P 500

VOO is the ticker symbol for the Vanguard S&P 500 ETF. It is an index fund, meaning it holds a basket of stocks designed to match the performance of a specific market index. In this case, VOO tracks the S&P 500, which contains 500 large-cap U.S. companies.

When you buy VOO, you own a small piece of all 500 companies in that index — Apple, Microsoft, Coca-Cola, and hundreds of others. The fund automatically rebalances to stay aligned with the index, so you do not have to pick individual stocks or time the market yourself.

VOO is structured as an ETF (exchange-traded fund), which means you can buy and sell it during market hours like a regular stock. This is different from a mutual fund, which only trades once per day after the market closes.

Key Takeaways

  • VOO holds the same 500 companies as the S&P 500 index, so its performance tracks that index closely.
  • You can buy VOO through any brokerage account — it trades on the stock market like a regular stock.
  • VOO charges a very low annual fee (expense ratio) of 0.03%, meaning you pay $3 per year for every $10,000 invested.
  • Because VOO is passively managed, it does not rely on a fund manager to pick stocks; it simply holds what the index holds.

How VOO tracks the S&P 500

The S&P 500 is a list of 500 large U.S. companies selected and weighted by market capitalization. That means bigger companies (by total stock value) make up a larger portion of the index. VOO holds those same 500 companies in the same proportions, so when the S&P 500 goes up or down, VOO moves almost identically.

The fund does not try to beat the market or pick winners. It simply mirrors the index. This is called passive management. Because there is no team of analysts trying to outperform the market, the costs are extremely low.

VOO's expense ratio is 0.03% annually. On a $10,000 investment, that is $3 per year. Compare that to actively managed funds, which often charge 0.5% to 1% or more because they employ managers and researchers.

Who owns VOO and why

VOO is one of the most popular index funds in the United States. Individual investors use it for retirement accounts (IRAs, 401(k)s), taxable brokerage accounts, and college savings plans. Institutional investors — pension funds, endowments, and insurance companies — also hold VOO in large quantities.

People choose VOO for several reasons. First, it offers broad diversification: you own 500 companies across many industries with a single purchase. Second, the cost is minimal, so more of your money stays invested rather than going to fees. Third, it requires no stock-picking skill or time commitment.

VOO is issued by Vanguard, a major investment company. Vanguard is structured as a mutual company owned by its funds, which means it has no outside shareholders pressuring it to maximize profits. This structure has made Vanguard known for keeping fees low across its product line.

How to buy VOO

You cannot buy VOO directly from Vanguard or the government. You must open a brokerage account with a financial institution that offers stock and ETF trading. Common brokerages include Fidelity, Charles Schwab, E-Trade, Robinhood, and many others.

Once your account is open and funded, you search for the ticker "VOO" in the trading platform and place a buy order. You can buy fractional shares, meaning you do not need $300 or $400 to start — you can invest $50 or $100 and own a proportional piece of the fund.

There are no special forms or waiting periods. The trade settles in two business days, and the shares appear in your account. You can hold VOO as long as you want, sell it whenever you choose, or set up automatic monthly purchases.

VOO versus other S&P 500 index funds

VOO is not the only S&P 500 index fund. Other major options include SPY (SPDR S&P 500 ETF), IVV (iShares Core S&P 500 ETF), and VFIAX (Vanguard S&P 500 Index Mutual Fund). All of these track the same index and perform nearly identically.

The differences are small. VOO and IVV both charge 0.03% annually. SPY charges 0.09%. VFIAX is a mutual fund rather than an ETF, so it trades once per day instead of continuously. If you are choosing between them, the expense ratio and account type (IRA, taxable, etc.) matter more than the fund name.

Some people choose VOO simply because it is well-known and has low costs. Others pick a different S&P 500 fund because their brokerage offers it commission-free or because they prefer the fund company. The performance difference over decades is negligible.

What VOO does not do

VOO does not may provide returns or protect you from losses. If the S&P 500 falls 20% in a year, VOO falls roughly 20% as well. Index funds move with the market, not against it.

VOO does not provide income in the form of dividends paid to you directly, though the companies inside it pay dividends. Those dividends are reinvested automatically within the fund, so your shares grow but you do not receive cash payments.

VOO does not adjust for inflation or economic cycles. It simply holds 500 large U.S. companies. If you want exposure to small-cap stocks, international stocks, bonds, or other asset types, you would need to buy additional funds.

Tax considerations when holding VOO

If you hold VOO in a tax-advantaged account like a 401(k) or traditional IRA, you pay no taxes on gains or dividends while the money is in the account. You only pay taxes when you withdraw in retirement.

If you hold VOO in a regular taxable brokerage account, you owe taxes on any gains when you sell, and on dividends each year. Because VOO is an ETF and is structured efficiently, it tends to generate fewer taxable events than actively managed funds, but taxes still apply.

If you buy VOO and hold it for more than one year before selling, any gains are taxed as long-term capital gains, which are usually taxed at lower rates than short-term gains. This is another reason many people hold index funds for decades rather than trading frequently.

Frequently Asked Questions

Is VOO safe?

VOO is as safe as the stock market itself. It does not may provide returns, and the value fluctuates daily. However, because it holds 500 different companies, it is less risky than owning a single stock. Over long periods (10+ years), the S&P 500 has historically trended upward, but past performance does not may provide future results.

Can I lose money in VOO?

Yes. If the stock market declines, VOO declines with it. During the 2008 financial crisis, the S&P 500 fell about 37%. VOO would have fallen similarly. However, investors who held through the downturn and did not sell recovered their losses within a few years as the market rebounded.

How often does VOO pay dividends?

VOO distributes dividends quarterly (four times per year). The amount varies depending on how much the 500 companies paid in dividends that quarter. In recent years, the annual dividend yield has been around 1.5% to 2%, meaning you receive that percentage of your investment value in dividends each year.

Can I use VOO in a retirement account?

Yes. VOO can be held in a traditional IRA, Roth IRA, 401(k), or any other retirement account your brokerage offers. Many people use VOO as a core holding in retirement accounts because of its low cost and broad diversification.

What happens if Vanguard goes out of business?

Your shares of VOO are held in your brokerage account, not by Vanguard directly. If Vanguard closed, the fund would be transferred to another provider or liquidated, and you would receive the cash value. Your shares are protected by the brokerage's insurance and regulatory safeguards.
