Wealthy PotSPY vs QQQ: The Two Most-Traded ETFs, Compared for Traders and Holders
SPY and QQQ are the ETFs that show up at the top of every volume table. Active traders treat them as the default instruments for the U.S. market and for big tech respectively, and a lot of long-term investors own them for the same reason. But they are not two flavors of the same thing. SPY owns the S&P 500, roughly 500 large companies across every sector. QQQ owns the Nasdaq-100, about 100 non-financial Nasdaq-listed companies, most of them technology. This comparison uses State Street's and Invesco's fund documents and SEC filings, and it treats the two audiences, traders and holders, separately, because the right answer differs for each.
The Short Answer
- Trading or hedging the broad U.S. market? SPY. It is the deepest, most liquid equity ETF in existence, with the largest options market of any listed fund. For a trader, that liquidity is the product.
- Trading or hedging large-cap tech? QQQ. Same story one tier down: enormous volume, a deep options chain, and since December 2025 a modern open-end structure.
- Holding for years? Neither, strictly. SPY at 0.0945% and QQQ at 0.18% are both undercut by same-index twins built for holders: VOO at 0.03% and QQQM at 0.15%. Pick the index first, then buy the cheaper wrapper.
Two Different Indexes
- SPY, the SPDR S&P 500 ETF Trust, launched on January 22, 1993 as the first U.S.-listed ETF. It tracks the S&P 500: about 500 large U.S. companies chosen by an S&P committee, spanning all eleven sectors.
- QQQ, the Invesco QQQ Trust, launched on March 10, 1999. It tracks the Nasdaq-100: the 100 largest non-financial companies listed on the Nasdaq exchange. The listing-venue rule is what makes it tech-heavy, and the no-financials rule means there are no banks, insurers, or payment networks inside. Nasdaq updated the index methodology on May 1, 2026, but the non-financial, Nasdaq-listed core did not change.
The overlap is real but narrow. The largest holdings of both funds are the same handful of mega-cap technology companies. Below that, SPY fans out into healthcare, financials, energy, industrials, and staples, while QQQ stays inside technology, communication services, consumer, and a little healthcare.

What Is Inside Each Fund
How much rides on the top 10 holdings
Higher bar = more concentrated in a few companies.
SPY holds ~504 stocks across all 11 sectors; QQQ holds ~102 and no financials. Source: State Street SPY page (Sep 2026) and Invesco QQQ semi-annual report (Mar 31, 2026).
Nearly half of QQQ sits in ten companies. The S&P 500 is itself top-heavy by historical standards, at around 38%, but QQQ takes that concentration and removes the cushion of 400 other businesses in unrelated industries. That is not a flaw; it is the design. Anyone buying QQQ is buying a focused position in the largest growth companies in America, and should expect it to behave like one. If you want a broad market position, SPY is a broad market position and QQQ is not. Our guide to diversifying to minimize risk explains why the number and spread of holdings matters more than the number of tickers you own.
Structure: The Roles Reversed in December 2025
For most of their history, SPY and QQQ shared an old-fashioned legal form. Both were unit investment trusts, a structure that predates modern ETF rules and comes with two handicaps: the trust must hold dividends as cash until the quarterly payout rather than reinvesting them, and it cannot lend out securities to earn a little offsetting income. On a rising market, idle dividend cash is a small drag, on the order of a few basis points a year.
That changed for QQQ. Effective after the close on December 19, 2025, following a shareholder vote, Invesco reorganized the trust into an open-end management investment company, the same structure used by VOO, IVV, and most modern ETFs. QQQ can now reinvest income and participate in securities lending, and the reorganization came with a fee cut from 0.20% to 0.18%. Its SEC filings for the period ending March 31, 2026 describe the new structure and the 0.18% unitary fee.
SPY did not follow. It remains a unit investment trust, so it still carries the cash-drag and no-lending quirks that older comparisons attribute to both funds. This matters mostly to long-term holders, where a few basis points compound. Traders holding for hours or days will never notice it. For a fuller treatment of what the UIT structure does and does not cost, see SPY vs VOO; for QQQ's conversion in detail, see QQQ vs QQQM.
Return and Drawdown
QQQ's ten-year average annual NAV return of about 22% against SPY's roughly 15% is a wide gap, and it is entirely a story about which sectors led. The Nasdaq-100's technology weight captured the strongest run large-cap growth has ever had. The same weighting cut the other way in the years when tech lagged: QQQ's own financial highlights show a −24.86% NAV total return for the fiscal year ending September 30, 2022, alongside gains of roughly 29% to 37% in the surrounding years. The Nasdaq-100 also fell far deeper than the S&P 500 in the 2000 to 2002 dot-com collapse and took far longer to recover.
The practical reading is that SPY and QQQ are not interchangeable at different risk settings; they are exposures to different things. If you hold QQQ, you are choosing a large-cap growth bet and should size it as one. If you hold SPY, you own the market and will get the market's result, whatever leads next.
For Buy-and-Hold, Both Have Cheaper Twins
Here is the part traders can skip and holders should not. Both funds charge more than the cheapest fund on their index, and both issuers, or their competitors, sell a lower-cost version aimed at people who never intend to trade:
- S&P 500: SPY charges 0.0945%. Vanguard's VOO charges 0.03% and, as an open-end fund, avoids the UIT quirks above. The full case is in SPY vs VOO.
- Nasdaq-100: QQQ charges 0.18%. Invesco's own QQQM charges 0.15% on the identical index. See QQQ vs QQQM.
The fee gaps are small in isolation, but for money you plan to hold for a decade or more there is no reason to pay for liquidity you will not use. Decide between the two indexes first, then buy the cheaper wrapper. If the real question you are asking is "Nasdaq-100 or S&P 500 for a long-term core," QQQ vs VOO is written for exactly that.
Which One Fits You
Choose SPY if: you trade or hedge the broad market, write or buy index options, or need to move large sums with the tightest possible spread. It is the most liquid equity ETF in the world, and that is worth its fee to the people who use it that way. For a long-term core in a retirement account, VOO gives you the same index cheaper.
Choose QQQ if: you trade or hedge large-cap tech and want the deepest Nasdaq-100 market, or you want a deliberate growth tilt and value QQQ's options liquidity. For a long-term Nasdaq-100 position, QQQM does the same job at a lower fee. Either way, treat the Nasdaq-100 as a concentrated satellite, not a substitute for a diversified core.
FAQ
Is SPY or QQQ better?
They track different indexes, so it depends on what you want to own. SPY is the diversified S&P 500 across all sectors; QQQ is the concentrated, tech-heavy Nasdaq-100. For trading, both are top-tier and SPY is the most liquid. For long-term holding, each has a cheaper twin: VOO for the S&P 500 and QQQM for the Nasdaq-100.
Do SPY and QQQ hold the same stocks?
They share the same mega-cap technology leaders at the top, but SPY holds about 500 companies across all eleven sectors while QQQ holds about 100 Nasdaq-listed non-financial companies. Roughly 400 of SPY's holdings, including every bank and insurer, are absent from QQQ.
Is QQQ still a unit investment trust like SPY?
No. QQQ converted to an open-end fund effective December 19, 2025, and can now reinvest dividends and lend securities. SPY remains a unit investment trust and still cannot do either.
Why has QQQ returned more than SPY?
Because large-cap technology led the market for most of the past decade and QQQ is concentrated in it. The same concentration produced a roughly 25% loss in QQQ's fiscal 2022 and much deeper losses than the S&P 500 in the dot-com crash. Past performance does not guarantee future results.
Are SPY and QQQ good long-term investments?
Both are sound funds, but both cost more than the cheapest fund on their index. Long-term holders usually do better with VOO (0.03% vs SPY's 0.0945%) or QQQM (0.15% vs QQQ's 0.18%), which own the same stocks.
