Over the ten years to the end of 2025, the Nasdaq 100 returned roughly +504% while the S&P 500 returned about +301%. That 200-point gap is why the Nasdaq 100 vs S&P 500 question dominates every "which index fund should I buy" search. But the headline hides the real story: the same index that ran that far ahead also fell 83% in the dot-com crash and took about 15 years to get your money back.
This guide gives you the verdict first, then the evidence — composition, returns, drawdowns, cost and volatility — so you can decide which index belongs at the core of your portfolio and which belongs as a tilt. If you want the structured version of everything below, our a structured ETF investing course walks through index selection step by step. This is education, not advice.
- The Nasdaq 100 is ~100 large non-financial companies, roughly 59% technology; the S&P 500 is ~500 companies across all 11 sectors.
- The Nasdaq 100 beat the S&P 500 in 7 of the last 10 calendar years — but fell 82.9% in 2000–02 versus 49.1% for the S&P.
- The two move together (0.92 correlation): owning both mostly doubles your bet on the same mega-cap tech names.
- For most investors the S&P 500 is the core and the Nasdaq 100 is a 5–20% growth tilt, not a whole portfolio.
Nasdaq 100 vs S&P 500: the verdict in 30 seconds
If you want one broad, diversified holding to build a portfolio around, the S&P 500 is the better default: cheaper, less concentrated, and spread across the whole US economy. The Nasdaq 100 is the higher-growth, higher-risk option — a concentrated bet on large-cap technology and consumer names that has paid off handsomely in the last decade and punished holders brutally in the two before it.
Neither is a "trade." Both are long-term index exposures. The real decision is not which one is good — both are — but how much volatility you can hold through without selling at the bottom. Get that honest, and the choice makes itself.
What's actually inside each index?
The Nasdaq 100 holds about 100 of the largest non-financial companies listed on the Nasdaq exchange, and roughly 59% of it sits in technology. The S&P 500 holds around 500 US companies weighted by market value and spans all 11 stock-market sectors, from banks and energy to healthcare and utilities. That single difference — sector spread — drives everything else you will read below.
The Nasdaq 100 also concentrates at the top. Its three largest sectors — technology, consumer discretionary and communication services — make up about 83% of the whole index. There are no financials and no real estate in it at all. So when you buy the Nasdaq 100, you are not buying "innovation" in the abstract; you are buying a specific, tech-led slice of the market.
The S&P 500 is not immune to concentration either — its biggest names now carry serious weight, which is worth understanding before you assume it is fully diversified. We covered exactly that in how seven mega-caps came to dominate the S&P 500. The point holds: the two indices overlap heavily at the top.
How much has the Nasdaq 100 really beaten the S&P 500?
By a lot — and consistently, in the recent past. The Nasdaq 100 has outperformed the S&P 500 in 7 of the last 10 calendar years (as of 30 June 2026). Over the decade to the end of 2025, it roughly doubled the S&P's cumulative return.

Here is what those two numbers say together: the Nasdaq 100 has delivered more, but it has not delivered something different. A 0.92 correlation means the two indices move in near-lockstep. When the S&P 500 has a bad day, the Nasdaq 100 almost always has a worse one. The outperformance is real; the diversification benefit of holding both is mostly an illusion.
What should you do with that? Treat past outperformance as a description of one favourable decade for technology, not a promise. The next section shows the bill that came with it.
The catch: what that outperformance costs you in a crash
Higher returns are the reward for holding higher risk — and the Nasdaq 100's risk shows up in drawdowns, the peak-to-trough falls that test whether you can actually stay invested.

In the dot-com collapse the Nasdaq 100 lost 82.9% while the S&P 500 lost 49.1% — and it took roughly 15 years to reclaim its 2000 high. In 2022 the pattern repeated at smaller scale: down 33.0% versus 18.1%. In both crashes, the tech-heavy index fell nearly twice as far.
What this means for you: a 50% fall needs a 100% gain to recover; an 83% fall needs a 490% gain. The deeper the hole, the more of your compounding is spent climbing out. If you would panic-sell at −40%, the Nasdaq 100 is not the index to build your core around, whatever its ten-year chart looks like.
QQQ vs VOO: cost, yield and concentration compared
Most investors do not buy the indices directly — they buy an ETF that tracks them. The two best-known are Invesco QQQ (Nasdaq 100) and Vanguard VOO (S&P 500). Here is how they line up on the factors that actually change your outcome.
| Factor | Nasdaq 100 (QQQ) | S&P 500 (VOO) |
|---|---|---|
| Holdings | ~102 companies | ~507 companies |
| Sector spread | ~59% technology; no financials | All 11 sectors |
| Top-10 concentration | ~47.4% | ~36.5% |
| Expense ratio | 0.18% (0.15% via QQQM) | 0.03% |
| Dividend yield | ~0.39% | ~1.05% |
| Recent record | Beat S&P in 7 of 10 years | The benchmark |

The cost gap is real but small in absolute terms. On a $50,000 position, the 0.15-point difference between VOO (0.03%) and QQQM (0.15%) is roughly $60 a year before compounding — illustrative, and far smaller than a single bad month of volatility. Cost should not be the deciding factor here; risk and concentration should.
Note the yield line too. VOO pays roughly two-and-a-half times the dividend income of QQQ, because the S&P 500 holds mature, cash-returning businesses the Nasdaq 100 leaves out. If you want your portfolio to pay you along the way, that matters. If you are choosing between fund wrappers more broadly, our guide to the difference between index funds and ETFs covers the structural side.
Is the Nasdaq 100 riskier than the S&P 500?
Yes — measurably. The Nasdaq 100 has run at an annualized volatility of about 18.9% versus roughly 16.0% for the S&P 500. That may sound modest, but volatility compounds into the far deeper drawdowns you saw above, and it hits hardest exactly when markets fall.
The risk is not random — it is structural. With about 59% in technology and no financials, energy or real estate to cushion it, the Nasdaq 100 rises fastest when tech is in favour and falls hardest when interest rates rise or growth stocks fall out of fashion. It is a factor bet dressed as a broad index.
Risk is also not the same as danger. Higher volatility is fine if your time horizon is long and your nerve holds. The problem is never the drawdown itself; it is the investor who sells into it. Match the index to the temperament, not the temperament to the chart.
One practical test: look at the −33% Nasdaq 100 fall of 2022 and ask honestly whether you would have kept buying through it or frozen. Your answer, not the ten-year return, is the number that should size your position.
Can you own both, and who should own which?
You can own both, and many people do — but understand what you are actually buying. Because the two indices correlate at 0.92 and share the same mega-cap names at the top, holding both does not diversify you much. It simply increases your technology weighting above what the S&P 500 already gives you.
That is not automatically wrong. A common, defensible approach is core-and-satellite: the S&P 500 as your diversified core, with the Nasdaq 100 layered on top as a deliberate 5–20% growth tilt. That gives you extra technology exposure in a size you have chosen on purpose, rather than by accident.
What you should not do is hold both in equal measure and tell yourself you are diversified. If you want genuinely different return streams, you diversify across regions, asset classes and company sizes — not across two US large-cap indices that own many of the same shares. For a sense of how much geography alone can change outcomes, see how the S&P 500 has compared with the FTSE 100.
There is also a behavioural trap worth naming. Investors often reach for the Nasdaq 100 after a long tech run, precisely when it looks unbeatable and its recent chart is steepest — then abandon it in the first deep drawdown. That is buying high and selling low with extra steps. The index did not fail them; the timing and the temperament did. Choosing your allocation calmly, in advance, is the only reliable defence against your own future panic.
So who should actually own which? Map the index to your goal, your horizon and your nerve, not to last year's return table:
- Choose the S&P 500 (VOO) as your core if you want one diversified, low-cost, income-paying holding you can leave untouched for decades. It is the sensible default for most portfolios.
- Add the Nasdaq 100 (QQQ or QQQM) as a tilt if you specifically want more technology-and-growth exposure, understand the deeper drawdowns, and have a horizon long enough to ride them out.
- Prefer QQQM over QQQ for buy-and-hold: same Nasdaq 100 index, lower ongoing cost. QQQ's extra liquidity mainly benefits active traders, not long-term holders.
- If a 40% fall would make you sell, keep the Nasdaq 100 small or skip it. An index you abandon at the bottom is worse than one you never bought.
