Is VOO a Good Investment?
VOO gives you the 500 largest U.S. companies for a 0.03% fee. It's an excellent core holding — but it's all large-cap U.S. stocks, with no small-caps or international exposure.
Don't have time? Here's what you need to know:
- 1VOO tracks the S&P 500 — the ~500 largest U.S. companies — at a 0.03% expense ratio, making it a strong low-cost core holding.
- 2The S&P 500 has averaged roughly 10% annually before inflation over the long run, though with steep drops in bear markets.
- 3VOO holds only U.S. large-caps, so it adds no small-cap or international exposure; VTI covers the full U.S. market for the same fee.
- 4It's ideal for long-term investors but not for money needed within a few years, since it can fall 30%+ in a downturn.
What VOO Actually Is
VOO is Vanguard's S&P 500 ETF. It holds the roughly 500 largest U.S. companies, weighted by market value, which means giants like Apple, Microsoft, and Nvidia make up a larger share than smaller members. Buying one share gives you a slice of the businesses that drive a huge portion of the U.S. economy.
Its headline strength is cost. VOO's expense ratio is just 0.03%, or about $3 a year per $10,000 invested — among the cheapest ways to own the U.S. large-cap market. Combined with the broad diversification of 500 companies across every sector, that low cost is why VOO is a default core holding for so many portfolios.
The Case For VOO
The S&P 500 has delivered an average annual return of roughly 10% before inflation over the very long run — not every year, but as a long-term average across decades that included crashes, recessions, and recoveries. VOO captures that return at minimal cost, and its passive, low-turnover structure also makes it relatively tax-efficient in a taxable account.
For most people, the appeal is simplicity that doesn't sacrifice quality. You get instant diversification across 500 companies, you're not betting on any single stock, and you avoid the high fees and underperformance that plague most active funds. It's a fund you can hold for decades and largely ignore.
| Fund | Index / coverage | Expense ratio |
|---|---|---|
| VOO | S&P 500 (large-cap U.S.) | 0.03% |
| IVV | S&P 500 (large-cap U.S.) | 0.03% |
| SPY | S&P 500 (large-cap U.S.) | 0.0945% |
| VTI | Entire U.S. market (incl. small/mid) | 0.03% |
Tip: VOO and IVV (iShares) both track the S&P 500 at 0.03%, so they're nearly interchangeable. SPY tracks the same index but costs more at 0.0945%.
Where VOO Falls Short
VOO isn't a complete portfolio on its own. It holds only large-cap U.S. stocks, so you get no exposure to U.S. small- and mid-caps or to international markets. If you want the entire U.S. market in one fund, VTI adds thousands of smaller companies for the same 0.03% fee; if you want global exposure, you'd pair it with an international fund.
It's also 100% stocks, which means full exposure to market downturns. The S&P 500 has fallen 30% to 50% in past bear markets, and VOO falls right along with it. That's the price of its long-run returns, and it's only appropriate for money you won't need for years and a stomach that can tolerate the swings.
Important: VOO is concentrated in its largest holdings — the biggest handful of tech-heavy companies can make up a substantial share of the fund, so it's less diversified than the '500 stocks' headline suggests.
Good for Whom — and Who Should Look Elsewhere
VOO is an excellent fit for long-term investors who want a simple, low-cost core of U.S. large-cap stocks — retirement savers, anyone building a three-fund portfolio, or a beginner who wants one solid holding to start with. Held for years inside a tax-advantaged or taxable account, it's hard to beat as a foundation.
It's a weaker standalone choice if you want broader diversification (VTI captures the full U.S. market), international exposure, or higher current income (a dividend fund like SCHD yields more). And it's not suitable for money you'll need within a few years, since it can drop sharply in a downturn.
Frequently Asked Questions
Is VOO a good investment for beginners?
Yes. VOO is one of the most beginner-friendly core holdings available: it gives you the 500 largest U.S. companies in a single, diversified fund for a 0.03% fee, with no stock-picking required. It's a sound foundation to hold for the long term, though pairing it with an international fund adds further diversification.
What's the difference between VOO and VTI?
VOO holds about 500 large-cap U.S. companies (the S&P 500), while VTI holds roughly 3,600 stocks covering the entire U.S. market, including small- and mid-caps. Both charge 0.03%, and their returns are similar because large caps dominate VTI too. VTI is slightly more diversified; VOO is more concentrated in the biggest companies.
Is VOO better than SPY?
For long-term buy-and-hold investors, VOO is generally better because it costs 0.03% versus SPY's 0.0945% while tracking the identical S&P 500 index. SPY's advantage is deeper trading liquidity, which matters to active traders and options users but not to someone investing steadily for retirement.
Can VOO lose money?
Yes. VOO is 100% stocks and falls with the market — the S&P 500 has dropped 30% to 50% in past bear markets, and VOO declines right along with it. Over long horizons it has historically recovered and grown, but it can post significant losses in any given year, so it's only suitable for money you won't need soon.
