VOO vs. VTI vs. QQQ: Which One Should You Buy?

VOO and VTI are both broad, cheap US stock funds from Vanguard. Either one can be the core of a portfolio. QQQ is narrower: 100 large, mostly tech companies listed on the Nasdaq. It costs more and swings harder.

VOO vs. VTI

VTI holds everything VOO holds, plus about 3,000 mid-size and small companies. Those smaller companies are only around 18% of VTI by value, so the two funds move almost in step. Both charge 0.03%. Pick one; you don't need both.

Where QQQ is different

• Concentrated in tech. Technology was about 69% of QQQ in mid-2026, compared with 41% of VTI.
• No financial companies. The Nasdaq-100 excludes banks and insurers by design.
• Bigger swings. QQQ has beaten the S&P 500 over the past decade, and it has also fallen further in downturns.
• Higher fee. 0.18% a year. Invesco's QQQM tracks the same index for less and is often the better buy-and-hold choice.

Owning more than one

The three funds share the same largest holdings. As of June 30, 2026, eight companies, led by Nvidia, Apple and Alphabet, made up about 34% of VOO, 30% of VTI and 41% of QQQ. Adding QQQ to VOO doesn't diversify you. It increases your bet on the same big tech stocks.

Where FXAIX fits

FXAIX is Fidelity's S&P 500 index mutual fund, at 0.015%. It holds the same stocks as VOO. If your account is at Fidelity and you want automatic monthly purchases, FXAIX is the simpler choice. At any other broker, VOO is easier to buy.

What's inside each fund

As of June 30, 2026, the same five companies led all three funds, but QQQ held more of each and much less of everything outside tech:

VOO's sector mix sits close to VTI's. If you want exposure to banks, insurers, energy and industrial companies, QQQ alone won't give it to you.

How each index is built

• S&P 500 (VOO): about 500 large US companies chosen by a committee at S&P Dow Jones Indices. A company needs to be large, widely traded and profitable to be added. Bigger companies get a bigger weight.
• CRSP US Total Market (VTI): nearly every US-listed stock, picked by rules rather than a committee, also weighted by size.
• Nasdaq-100 (QQQ): the 100 largest non-financial companies listed on the Nasdaq exchange, including a few based outside the US. Companies listed on the New York Stock Exchange, such as Berkshire Hathaway or JPMorgan, aren't eligible, however large they are. Weights are capped so no single company dominates, and the list is reviewed every December.

How the funds are structured

VOO and VTI are ETF share classes of larger Vanguard index funds, which helps them avoid passing taxable capital gains on to shareholders. QQQ is an older structure called a unit investment trust. It can't lend out its shares for extra income or reinvest dividends between payouts, which is part of why it costs more. QQQM, launched in 2020, is a standard ETF that tracks the same index at 0.15%.

What $500 a month could grow to

Investing $500 a month for 20 years, at a hypothetical 8% average yearly return, would grow to about $294,000, from $120,000 of contributions. At the same return, the fee gap between VOO and QQQ would cost a few thousand dollars over that time. The bigger difference is that QQQ's actual returns could be far higher or far lower than VOO's, because it's less diversified.

Taxes and which account to use

• Roth IRA: a good home for any of the three. Growth and withdrawals in retirement are tax-free. See how to open a Roth IRA.
• Taxable account: all three are tax-efficient and have rarely paid out capital gains. Their dividends are mostly "qualified," taxed at the lower long-term rate.
• 401(k): you usually can't buy ETFs, but most plans offer an S&P 500 or total-market index fund that does the same job.

Dividends

All three pay dividends quarterly. VOO and VTI yield about 1.1% a year, so $10,000 pays roughly $110. QQQ yields about 0.5%, or roughly $50. Most brokers let you reinvest dividends automatically, which is usually the right choice while you're building savings.

How to buy them

1. Open a brokerage account or IRA at a broker with no account fees, such as Fidelity, Schwab or Vanguard.
2. Transfer money from your bank.
3. Search for the ticker (VOO, VTI or QQQM) and enter a dollar amount; most brokers allow fractional shares.
4. Turn on dividend reinvestment and set up a recurring purchase.

Which to pick

• One fund for most of your money: VOO or VTI.
• You're at Fidelity: FXAIX, or FZROX.
• You want extra tech growth and can stand bigger drops: a small slice of QQQ or QQQM on top of your core fund.

Performance and drops

QQQ's past decade was driven by a handful of tech giants. That can continue, but the same concentration is what made its losses much deeper in tech-led selloffs. Past returns don't predict future ones.

Does the fee difference matter?

On $10,000 invested for 20 years at an 8% yearly return, VOO's 0.03% fee leaves you about $46,300. QQQ's 0.18% fee leaves about $45,100, roughly $1,300 less. It matters, but it's smaller than the difference in how the funds behave. QQQM, which tracks the same index at 0.15%, narrows the gap slightly.

Same index, other funds

SPY trades the most and is popular with active traders, but for buying and holding, VOO or IVV costs less every year.

Who each fund suits

• VOO: you want the 500 biggest US companies, the index most people mean by "the market."
• VTI: you want every US company, including small ones, in one fund.
• QQQ or QQQM: you already own a broad fund and want a smaller extra bet on large growth companies, and you can sit through drops of a third or more.

Example mixes

Whatever mix you choose, set up automatic purchases and rebalance once a year.
