What the QQQ ETF Is and How It Tracks the Nasdaq-100

QQQ is an exchange-traded fund that holds the 100 largest non-financial companies on the Nasdaq stock exchange

QQQ is the ticker symbol for the Invesco QQQ Trust, an exchange-traded fund (ETF) that tracks the Nasdaq-100 Index. When you buy one share of QQQ, you own a small piece of 100 large companies — mostly technology firms, but also companies in healthcare, consumer goods, and other sectors. The fund is weighted by market value, meaning the largest companies make up a bigger portion of the fund than smaller ones.

QQQ trades on the Nasdaq stock exchange just like individual stocks do. You can buy and sell it during market hours through any brokerage account. The fund holds actual shares in each of the 100 companies it tracks, and it rebalances quarterly to stay aligned with the Nasdaq-100 Index.

The Nasdaq-100 excludes financial companies — banks, insurance firms, and investment companies are not included. This is different from the S&P 500, which includes financial firms and covers 500 companies across all sectors. Because of this focus, QQQ is heavily weighted toward technology stocks, which makes up roughly 45 to 50 percent of the fund depending on market conditions.

Key Takeaways

• QQQ holds 100 large non-financial companies and is heavily weighted toward technology stocks, making it more volatile than broader market indexes.
• You can buy and sell QQQ shares during regular market hours through any brokerage, and the price changes throughout the day like any stock.
• The fund charges an expense ratio — a yearly fee expressed as a percentage — that covers the cost of managing and operating the fund.
• QQQ is rebalanced quarterly, meaning the fund adjusts its holdings to match the current composition of the Nasdaq-100 Index.

How QQQ differs from other broad market ETFs

QQQ is narrower and more concentrated than funds that track the entire S&P 500 or the total U.S. stock market. Because it holds only 100 companies instead of 500 or 3,000, a single company's performance has a larger effect on QQQ's price. When technology stocks rise sharply, QQQ typically rises faster than a fund tracking the S&P 500. When technology stocks fall, QQQ typically falls faster as well.

The Nasdaq-100's exclusion of financial companies also shapes how QQQ moves. During periods when banks and insurance companies outperform, QQQ may lag behind the S&P 500. During periods when technology leads, QQQ often outperforms.

QQQ is also different from the Nasdaq Composite, which includes all stocks listed on the Nasdaq exchange — thousands of companies, including small ones. The Nasdaq-100 focuses only on the largest and most liquid companies, which is why QQQ is more stable than an ETF tracking the full Nasdaq Composite would be.

What companies are in QQQ

The top holdings in QQQ change based on market value, but they typically include Microsoft, Apple, Nvidia, Amazon, Tesla, Meta, Broadcom, and other large technology and consumer companies. The exact list shifts as companies grow or shrink in market value. You can see the current holdings and their weights on the Invesco website, which updates daily.

Because QQQ is market-cap weighted, the largest companies have the most influence on the fund's price movement. The top 10 holdings usually represent about 45 to 50 percent of the fund's total value. This concentration means that when a few very large companies move sharply, QQQ moves sharply too.

The expense ratio and costs of owning QQQ

QQQ charges an expense ratio of 0.20 percent per year. This means that if you own $10,000 in QQQ, you pay $20 per year in fees. The expense ratio is deducted automatically from the fund's returns, so you do not see a separate bill — it straightforward reduces the value of your shares slightly each year.

Beyond the expense ratio, you may pay a brokerage commission when you buy or sell QQQ shares, depending on your brokerage. Many brokerages now offer commission-free trading on ETFs, so this cost may be zero. You will also owe capital gains tax on any profit when you sell shares outside a tax-advantaged account like a 401(k) or IRA.

How QQQ's price moves during the day

QQQ's price changes throughout each trading day as investors buy and sell shares. The price reflects the current market value of the 100 companies it holds. If those companies' stock prices rise, QQQ's price rises. If they fall, QQQ's price falls.

Because QQQ is heavily weighted toward technology stocks, it tends to be more volatile than funds tracking the broader market. On days when technology stocks surge, QQQ often rises more than the S&P 500. On days when technology stocks decline, QQQ often falls more. This higher volatility appeals to some investors but makes QQQ riskier for those with a low tolerance for price swings.

QQQ versus individual stock picking

Buying QQQ gives you exposure to 100 large companies in a single transaction, whereas buying individual stocks requires you to research and purchase each one separately. QQQ's diversification means that if one company performs poorly, the impact on your overall investment is smaller than if you owned only that stock.

QQQ also requires far less ongoing research and monitoring than a portfolio of individual stocks. You do not need to track earnings reports, management changes, or competitive threats for each company — the index automatically includes the 100 largest non-financial firms, and the fund rebalances quarterly to maintain that focus.

The trade-off is that you own all 100 companies whether you think they are all good investments or not. If you believe certain companies are overvalued, you cannot exclude them from QQQ the way you could if you were picking stocks individually.

Tax treatment of QQQ in different account types

In a taxable brokerage account, you owe capital gains tax on any profit when you sell QQQ shares. If you hold QQQ for more than one year before selling, you pay long-term capital gains tax, which is usually lower than short-term rates. You may also owe tax on any dividends QQQ distributes, though the dividend yield is typically low because many of the companies in the fund reinvest profits rather than paying dividends.

In a tax-advantaged account like a traditional IRA, Roth IRA, or 401(k), you can buy and sell QQQ without triggering capital gains tax each year. In a traditional IRA or 401(k), you pay tax on withdrawals in retirement. In a Roth IRA, withdrawals in retirement are tax-free if you meet the account rules.

Frequently Asked Questions

Is QQQ the same as the Nasdaq-100?

No. The Nasdaq-100 is an index — a list of 100 companies and their weights. QQQ is an ETF that holds shares in those 100 companies and tracks the index. The index itself is not something you can buy; QQQ is the fund you buy to own a piece of all 100 companies at once.

Can I buy QQQ in a retirement account?

Yes. You can hold QQQ in a traditional IRA, Roth IRA, 401(k), or any other brokerage account. The tax treatment depends on the account type — in a Roth IRA, growth is tax-free; in a traditional IRA or 401(k), you pay tax on withdrawals later.

What happens if a company in QQQ goes bankrupt?

If a company in the Nasdaq-100 falls out of the top 100 by market value or is delisted, Invesco removes it from the fund during the next quarterly rebalance and replaces it with the next-largest may be able to access company. Your shares in QQQ are not affected — the fund straightforward adjusts its holdings.

Does QQQ pay dividends?

QQQ distributes dividends, but the yield is typically low — usually between 0.5 and 1 percent per year — because many technology companies reinvest profits rather than pay dividends. Dividend payments are made quarterly and are automatically reinvested if you have that option enabled at your brokerage.

How is QQQ different from VOO or VTI?

VOO tracks the S&P 500 (500 companies across all sectors, including financials) and VTI tracks the entire U.S. stock market (thousands of companies). QQQ tracks only 100 non-financial companies, so it is more concentrated and more heavily weighted toward technology. This makes QQQ more volatile but also means it can outperform during technology-led market rallies.
