Short answer: VOO is the better default for most investors — about 500 large U.S. companies across every sector for just 0.03% a year. QQQ is a concentrated bet on big technology and growth stocks: it returned roughly 20.9% a year over the decade to September 2026, against about 15.3% for VOO, but it fell about 33% in 2022 while VOO fell about 18%. Pick VOO as your core; add QQQ only as a smaller growth tilt.
What each fund actually owns
VOO, the Vanguard S&P 500 ETF, tracks the S&P 500 — roughly 500 of the largest U.S. companies across all eleven sectors. As of August 31, 2026, it held 505 stocks, with information technology its largest sector at about 37.9%.
QQQ, the Invesco QQQ Trust, tracks the Nasdaq-100 — the 100 largest non-financial Nasdaq-listed companies. By index rule it holds no banks, insurers, or exchanges. As of October 2026 it held about 102 positions, and technology made up roughly 68% of the fund. That is the whole difference in one number: VOO is the broad U.S. market; QQQ is mostly a technology fund.
Both share the same giants at the top — Nvidia, Apple, and Microsoft — but concentration differs: VOO’s top ten made up about 37.8% of the fund, QQQ’s about 46.8%, with Nvidia alone at about 8.3%.
What it costs
VOO charges 0.03% a year. QQQ charges 0.18% — six times as much. On $100,000, that is $30 a year for VOO against $180 for QQQ.
In December 2025 QQQ converted from a unit investment trust into a regular open-end ETF, cutting its fee from 0.20% to 0.18%; Invesco also offers QQQM, a near-identical fund at 0.15%.
The returns: QQQ won the decade
Over the ten years to late 2026, QQQ beat VOO by a wide margin. Vanguard reported VOO’s 10-year annualized return at 15.29% through September 30, 2026; Invesco reported QQQ’s cumulative 10-year return at 567.65% through September 29, 2026 — roughly 20.9% a year.
Verified example: $10,000 in each fund ten years ago, dividends reinvested.
- VOO at 15.29% a year: $10,000 × 1.1529¹⁰ = $41,487
- QQQ at 20.9% a year: $10,000 × 1.209¹⁰ = $66,721
- Difference: $25,234 on the same starting amount
That gap is the reward for owning more of the decade’s winners — the big technology and AI names. It is also backward-looking: the same concentration that produced it is what makes QQQ fall further when those companies stumble. Our VOO calculator models what different return assumptions do to a long-term balance, and our compound interest calculator shows how small annual differences snowball.
The risk side: QQQ falls much harder
In 2022, when rising rates punished growth stocks, VOO fell about 18% while QQQ fell about 33%. On a $100,000 portfolio, that is $82,000 versus $67,000 at year-end — the kind of drop that pushes many investors to sell at exactly the wrong moment.
During the dot-com bust of 2000–2002, the Nasdaq-100 fell roughly 83% from peak to trough. QQQ eventually recovered and went on to its record decade, but an investor who needed the money — or panicked — during those years never got the recovery.
Owning both does not diversify much
A common instinct is to buy both and call it diversification. It barely is: the two funds share about 85 holdings, and roughly 94% of QQQ’s assets are also held by VOO. Buying QQQ on top of VOO mostly just increases your weight in the same mega-cap technology stocks.
If you already hold VOO and want real diversification, look elsewhere: smaller U.S. companies, international stocks, or bonds. Adding QQQ is a decision to tilt harder toward growth, not to spread risk. Our guide to dollar-cost averaging explains how to build a position gradually, which softens the risk of buying at a peak.
Which one fits you?
- Pick VOO as your core if you want one fund to hold for decades at the lowest cost with the broadest exposure — the default for retirement accounts. Pair it with our guide on how much to save for retirement by age.
- Add QQQ as a tilt if you believe large technology companies will keep outgrowing the market, you have a horizon of ten years or more, and you can watch a third of your balance disappear without selling — a common shape is 70–80% VOO with 20–30% QQQ.
- Pick QQQ alone only if you understand you are holding a concentrated growth fund, not a diversified market portfolio, and you are comfortable with 30%-plus drawdowns.
- Inside a 401(k) or IRA, the same logic applies — decide which account to fund first with our 401(k) vs IRA guide, then choose the fund inside it.
Past returns do not predict future ones. But the structural facts will not change: VOO is broader, cheaper, and calmer; QQQ is narrower, pricier, and more volatile. Choose based on which trade-offs you can live with for ten years. For the official background on how ETFs work, see the U.S. Securities and Exchange Commission’s investor education site.
Frequently asked questions
Is VOO or QQQ better for beginners?
VOO is the better starting point: about 500 companies across every sector for 0.03% a year, so one purchase gives you the broad U.S. market. QQQ is valid too, but its concentration in about 100 mostly technology stocks means bigger swings, and beginners are more likely to panic-sell during a 30% drop.
Can I hold both VOO and QQQ?
Yes — typically VOO as the core with QQQ as a smaller growth tilt, such as 80% VOO and 20% QQQ. Do not mistake it for diversification, though: about 94% of QQQ’s assets are already inside VOO. For genuine diversification, add international stocks or bonds instead.
Why is QQQ’s expense ratio higher than VOO’s?
QQQ tracks the Nasdaq-100 and Invesco prices it at 0.18% a year against Vanguard’s 0.03% for VOO. The fee fell from 0.20% to 0.18% in December 2025, when QQQ converted from a unit investment trust to a regular open-end ETF. Its near-identical sibling QQQM tracks the same index for 0.15%.
Did QQQ really beat VOO over the last 10 years?
Yes, by a large margin. Over the decade to late September 2026, QQQ returned roughly 20.9% a year against about 15.3% for VOO, turning $10,000 into roughly $66,700 versus roughly $41,500 with dividends reinvested. But QQQ also fell about 33% in 2022 against VOO’s 18%, and about 83% in the 2000–2002 dot-com bust — with no guarantee the next decade repeats it.
