Comparisons7 min readUpdated March 17, 2026

Key Takeaways

✓SPY tracks 500 stocks across all sectors; QQQ tracks 100 non-financial Nasdaq stocks with heavy tech weighting.
✓QQQ has outperformed SPY over the past decade due to tech dominance, but with higher volatility.
✓SPY charges 0.0945% while QQQ charges 0.20% — both higher than cheaper alternatives.
✓SPY offers broader diversification; QQQ is essentially a concentrated growth/tech bet.

QQQ and SPY are two of the most popular ETFs in the world, with combined assets exceeding $1 trillion. Both provide large-cap US stock exposure, but their index methodologies and sector compositions create meaningfully different investment experiences.

Index Differences

SPY tracks the S&P 500 — 500 large-cap companies selected by a committee based on size, profitability, and liquidity, weighted by market capitalization across all sectors. QQQ tracks the Nasdaq-100 — the 100 largest non-financial companies listed on the Nasdaq exchange, also cap-weighted but inherently tilted toward technology and growth.

The key distinction: SPY includes financials, energy, utilities, and other traditional economy sectors that QQQ excludes. QQQ concentrates in technology, consumer discretionary, and communications, creating what is essentially a mega-cap growth bet.

Performance Comparison

QQQ has dramatically outperformed SPY during the tech-led bull market of the 2010s and 2020s. However, during the dot-com crash (2000-2002), QQQ lost over 80% while SPY declined about 45%. During the 2022 downturn, QQQ fell 33% versus SPY's 19%. Higher returns come with higher risk — there is no free lunch.

The Overlap Issue

Roughly 40% of SPY's market cap overlaps with QQQ. The mega-cap tech companies dominate both indexes. Holding both SPY and QQQ does not provide as much diversification as many investors believe — it effectively doubles down on big tech exposure. If you want QQQ-like returns with some diversification, consider VUG (growth) or hold SPY alongside a dedicated small-cap or value ETF.

Which Should You Choose?

SPY (or the cheaper VOO) is the better default for most investors because it provides broader market coverage. QQQ makes sense as a satellite position for investors who want to overweight technology and growth stocks. Holding both is acceptable if you understand and intentionally want the increased tech concentration. Visit our education center for portfolio allocation guidance.

Frequently Asked Questions

Is QQQ better than SPY?

QQQ has outperformed SPY during the recent tech-led bull market, but it is not inherently better. QQQ concentrates in technology and growth stocks, making it more volatile. In the 2000-2002 dot-com crash, QQQ lost over 80% while SPY lost about 45%. The better choice depends on your risk tolerance and existing portfolio composition.

Can I hold both QQQ and SPY?

You can, but there is significant overlap. Roughly 40% of SPY's weight overlaps with QQQ holdings since the largest tech companies dominate both indexes. Holding both increases your tech concentration. If you want broader coverage, pair SPY with a small-cap or international ETF instead.

Are there cheaper alternatives to QQQ and SPY?

Yes. VOO and IVV track the S&P 500 at 0.03% versus SPY's 0.0945%. QQQM is an identical Nasdaq 100 ETF at 0.15% versus QQQ's 0.20%. For long-term holding, the cheaper alternatives are preferable unless you need SPY's unmatched trading liquidity.
