QQQ and VOO are two of the most heavily traded ETFs in the world, and they’re often framed as a straightforward “growth vs. core” choice. That framing is roughly right, but it undersells how much these two funds actually overlap — and how much of the performance gap between them comes down to a handful of shared mega-cap holdings carrying different weights in each fund, rather than two entirely different portfolios.
This guide breaks down exactly where QQQ and VOO converge, where they diverge, and what that means for the “should I own one, the other, or both” question.
The Quick Answer
VOO tracks the S&P 500 — roughly 500 large U.S. companies across every major sector, including financials, healthcare, energy, and consumer staples. QQQ tracks the Nasdaq-100 — the 100 largest non-financial companies listed on the Nasdaq exchange, which in practice means a fund concentrated heavily in technology, with zero exposure to banks or financial institutions by design.
Because of that concentration, QQQ has delivered a notably higher historical return than VOO over the past decade, with meaningfully higher volatility and deeper drawdowns during downturns. The two funds are also more correlated than their different index names might suggest — sharing the large majority of their largest holdings — which matters if you’re considering holding both.

What Each Fund Actually Tracks
VOO holds roughly 500 large-cap U.S. companies selected by an S&P index committee to represent the broad U.S. large-cap market — spanning technology, financials, healthcare, energy, consumer staples, industrials, and more. It’s designed to be a snapshot of the large-cap U.S. economy as a whole.
QQQ is structurally different in an important way: it only includes companies listed on the Nasdaq exchange, and it explicitly excludes financial companies by the index’s own rules. That’s not a subtle tilt — it’s a hard structural exclusion. The result is a fund where technology, communication services, and consumer discretionary companies dominate, with no exposure at all to banks, insurers, or other financial institutions that make up a meaningful chunk of VOO.
This is the single biggest thing to understand about QQQ vs. VOO: you’re not just choosing “more tech” — you’re choosing a fund that structurally cannot hold an entire sector (financials) that VOO does hold.
Portfolio Overlap: More Than You’d Expect
Despite tracking different indexes, QQQ and VOO share a surprising amount of overlap at the holdings level. Recent fund analytics show roughly 86 shared holdings between the two funds, representing around 81% portfolio overlap by holding count and a combined overlap weight of nearly 55% of total assets — driven largely by shared mega-cap positions like Nvidia, Apple, and Microsoft sitting near the top of both funds.
That overlap is exactly why the two funds are correlated as highly as they are (recent correlation estimates range from roughly 0.90 to 0.93). The practical takeaway: QQQ isn’t a completely separate bet from VOO — it’s better understood as a concentrated, tech-and-financial-exclusion tilt built largely from a subset of the same mega-cap companies that already sit near the top of VOO, just weighted far more heavily and without the diversifying sectors VOO also holds.
Performance: Why the Gap Exists
Over the trailing 10-year period, QQQ has posted a notably higher annualized return than VOO according to third-party ETF analytics platforms — a gap that’s almost entirely explained by the concentration difference above. Large-cap technology and AI-adjacent companies have been the strongest-performing segment of the U.S. market for most of the past decade, and QQQ simply holds more of that segment, at higher weights, than VOO does.
This is a look backward, not a forecast. The same concentration that has driven QQQ’s outperformance during a tech-led bull market is the same mechanical reason it has also underperformed more sharply during periods when tech specifically has fallen out of favor — including notable stretches like the 2022 bear market, when QQQ’s decline outpaced VOO’s by a wide margin. There have also been much longer historical periods — including the years following the early-2000s dot-com decline — where a Nasdaq-heavy fund like QQQ underperformed a broader index for an extended stretch. Past performance, in either direction, doesn’t guarantee what happens next.
Volatility and Drawdowns
This is where the practical difference between these two funds shows up most clearly in day-to-day investing terms, not just in a headline return number.
QQQ’s volatility (measured by standard deviation) has run meaningfully higher than VOO’s — roughly 27% versus 17% over a recent five-year measurement window, according to third-party fund analytics. Its beta relative to the broader market also sits above 1.0, meaning it tends to amplify overall market moves in both directions.
Drawdowns tell a similar story: QQQ’s worst historical peak-to-trough decline has been somewhat deeper than VOO’s (in the mid-to-high 30% range for both funds, with QQQ consistently coming in worse), and during the 2022 downturn specifically, QQQ’s decline notably outpaced VOO’s over the same stretch. If you’re the kind of investor who finds it difficult to stay invested through a sharper decline, this volatility gap is worth weighing seriously — it’s not just a statistic, it’s a description of what actually holding this fund through a downturn has felt like.
Dividends
VOO’s diversified holdings across sectors — including financials, consumer staples, and healthcare, which tend to pay more substantial dividends than growth-oriented technology companies — give it a meaningfully higher dividend yield than QQQ, whose Nasdaq-100 companies more often reinvest profits into growth rather than paying it out as dividends. Neither fund is designed as an income-focused holding, but if current dividend income matters to your strategy, VOO’s yield profile is the more natural fit of the two.
Can You Hold Both?
Given a correlation in the 0.90-0.93 range and roughly 55% overlapping asset weight, holding both QQQ and VOO provides less diversification benefit than the “different index, different fund” framing might suggest. You’re not combining two unrelated strategies — you’re layering a concentrated tech/growth tilt on top of a broad index that already includes most of the same top holdings.
That said, some investors do intentionally combine the two: using VOO (or a broader fund like VTI) as the diversified core of a portfolio, with a smaller QQQ allocation layered on top specifically to increase exposure to growth and technology beyond what VOO’s market-cap weighting alone would provide. This is a deliberate concentration decision, not a way to add meaningful new diversification — worth understanding clearly before combining the two.
Rebalancing and Index Turnover
VOO’s underlying S&P 500 Index is reviewed quarterly by an index committee, which can add or remove companies based on eligibility criteria like market cap, liquidity, and profitability — a process that involves some judgment, not just a mechanical formula. QQQ’s Nasdaq-100 also rebalances on a set schedule, with an additional annual reconstitution each December, and includes specific rules that cap how concentrated any single holding can become, to keep the index from becoming excessively dominated by one or two companies.
Both funds are considered relatively low-turnover, tax-efficient index-based ETFs compared to actively managed alternatives — neither generates frequent trading activity purely to chase short-term opportunities, since both are simply following their respective index’s published rules.
Tax Considerations
Both QQQ and VOO primarily distribute qualified dividends, which are generally taxed at the lower long-term capital gains rates rather than ordinary income rates — though QQQ’s much smaller dividend payout means this matters less in practice for QQQ holders, simply because there’s less dividend income to tax in the first place. Both funds also benefit from the standard ETF creation/redemption structure that tends to minimize unexpected capital gains distributions, a structural advantage ETFs generally have over traditional mutual funds regardless of which of these two you choose. This is general tax information, not personalized advice — a tax professional can confirm how this applies to your specific situation and account type.
Which One Fits Your Situation?
VOO may be a better fit if:
- You want broad diversification across every major sector, including financials, healthcare, and consumer staples
- You’re not comfortable with the higher volatility and deeper historical drawdowns that come with QQQ’s concentration
- You want a fund more people would recognize as “the stock market” — the S&P 500 is the most widely cited U.S. market benchmark
QQQ may be a better fit if:
- You specifically want concentrated exposure to large-cap technology and growth companies
- You understand and accept meaningfully higher volatility and steeper potential drawdowns in exchange for that concentration
- You’re using it as a deliberate satellite tilt on top of a diversified core, rather than as your only holding

Frequently Asked Questions
Is QQQ riskier than VOO? Generally yes, based on historical volatility and drawdown data — QQQ’s concentration in technology and its exclusion of financials has historically produced larger price swings in both directions compared to VOO’s broader diversification across sectors.
Why doesn’t QQQ include any bank stocks? The Nasdaq-100 Index, which QQQ tracks, excludes financial companies by its own index construction rules — it’s a structural feature of the index, not an active investment decision by the fund manager.
Has QQQ always outperformed VOO? No. While QQQ has outperformed VOO over the trailing 10-year period through 2026, there have been extended historical periods — including the years following the early-2000s dot-com downturn — where a Nasdaq-heavy fund underperformed the broader market for a prolonged stretch. Recent outperformance reflects a specific tech-led bull market, not a permanent pattern.
Should I replace VOO with QQQ for higher returns? That depends entirely on your risk tolerance and time horizon — this article isn’t a recommendation either way. QQQ’s higher historical returns have come with meaningfully higher volatility and steeper drawdowns, which is a trade-off, not a strictly “better” outcome for every investor.
Do QQQ and VOO provide real diversification if I hold both? Only partially. Their correlation and portfolio overlap are both high, meaning you’re mostly layering additional concentration in shared mega-cap holdings rather than adding a genuinely different exposure. Some investors do this deliberately as a growth tilt, understanding it isn’t the same as diversifying into a different asset class or region.
Which fund is cheaper to hold? VOO’s 0.03% expense ratio is considerably lower than QQQ’s 0.18%. On a $10,000 investment, that’s roughly $3 a year for VOO versus $18 a year for QQQ — a modest difference in isolation, but one more factor in the overall comparison.
