If you want exposure to some of the largest growth-oriented companies in the U.S., the Nasdaq-100 is one of the key indexes to know. A range of ETFs are designed to provide exposure to the index, from traditional index-tracking funds to leveraged and inverse products.
Among the most widely known are Invesco’s QQQ and QQQM, both of which track the Nasdaq-100 Index, as well as ProShares’ TQQQ and SQQQ, which seek to deliver 3x and -3x the index’s daily performance, respectively.
Although all four ETFs are linked to the Nasdaq-100, they serve very different purposes. Understanding how they work—and how they differ—is essential before considering which type of product fits a particular investment objective.
1. What Is the Nasdaq-100?
The Nasdaq-100 Index (NDX) was launched in 1985 and consists of 100 of the largest non-financial companies listed on the Nasdaq Stock Market. The index uses a modified market-capitalization weighting methodology, is rebalanced quarterly, and undergoes an annual reconstitution.
Because financial companies are excluded, the Nasdaq-100 has a different composition from broader U.S. stock indexes such as the S&P 500. Technology companies account for a significant portion of the index, but the Nasdaq-100 is not simply a technology index. Its constituents span multiple industries, including consumer discretionary, healthcare, communication services, and other sectors.
The Nasdaq-100 also includes many of the world’s best-known companies, including NVIDIA, Apple, Microsoft, Amazon, Alphabet, Tesla, Meta Platforms, Broadcom, Walmart, and Netflix. Its constituents span areas such as AI, semiconductors, cloud computing, software, e-commerce, social media, and consumer products, giving investors exposure to many of the largest and most influential companies listed on the Nasdaq.
For investors seeking broad exposure to the Nasdaq-100, QQQ and QQQM offer traditional index exposure, while TQQQ and SQQQ add daily leverage or inverse exposure to the equation.
2. QQQ: A Long-Established and Highly Traded Nasdaq-100 ETF
Invesco QQQ (ticker: QQQ) was launched on March 10, 1999, making it one of the longest-running ETFs tracking the Nasdaq-100.
QQQ seeks to track the performance of the Nasdaq-100 Index, giving investors exposure to the companies that make up the index through a single ETF.
As of 2026, QQQ has a total expense ratio of 0.18%.
Investors should be aware that older sources may still show a 0.20% expense ratio. Invesco reduced QQQ’s expense ratio to 0.18% following a structural change completed in late 2025. The change did not alter QQQ’s core objective of tracking the Nasdaq-100.
Another notable characteristic of QQQ is its high trading activity. For investors who place a strong emphasis on trading liquidity or access to options, QQQ’s established trading market can be an important consideration.
In simple terms:
QQQ is a long-established, highly traded ETF designed to provide direct exposure to the Nasdaq-100.
3. QQQM: Similar Nasdaq-100 Exposure at a Lower Expense Ratio
Invesco NASDAQ 100 ETF (ticker: QQQM) was launched on October 13, 2020, and also tracks the Nasdaq-100 Index.
The most obvious difference between QQQ and QQQM is their expense ratios.
As of 2026, QQQM has a total expense ratio of 0.15%, compared with 0.18% for QQQ.
Because both ETFs track the same underlying index, their overall market exposure is broadly similar. Invesco introduced QQQM as a lower-cost way for investors to gain exposure to the Nasdaq-100, particularly for those focused on long-term investing.
In simple terms:
QQQ: A longer-established ETF with high trading activity.
QQQM: A lower-cost Nasdaq-100 ETF that may appeal to investors focused on long-term holding costs.
For investors primarily interested in long-term Nasdaq-100 exposure, the key differences to consider between QQQ and QQQM are therefore cost and trading needs.
A lower expense ratio does not guarantee higher investment returns. Actual returns can also be affected by trading costs, market conditions, and tracking differences.
4. TQQQ: A Daily 3x Leveraged Nasdaq-100 ETF
While QQQ and QQQM are traditional index ETFs, TQQQ is a fundamentally different type of product.
ProShares UltraPro QQQ (ticker: TQQQ) seeks to provide 3x the daily performance of the Nasdaq-100 Index, before fees and expenses.
For example, if the Nasdaq-100 rises 10% on a particular trading day, TQQQ’s daily target would be approximately a 30% gain, before fees and other factors.
Conversely, if the Nasdaq-100 falls 10% in a single day, TQQQ’s daily target would be approximately a 30% loss.
TQQQ was launched on February 9, 2010. As of 2026, its total expense ratio is 0.97%, while its net expense ratio is 0.82% under the applicable fee waiver arrangement.
However, the most important word in TQQQ’s investment objective is “daily.”
TQQQ seeks to deliver 3x the index’s performance for a single day. It does not promise to deliver three times the Nasdaq-100’s cumulative return over a month, a year, or any other longer period.
Why Isn't TQQQ's Long-Term Return Simply 3x?
The key reason is the ETF’s daily reset mechanism.
Consider a simplified example in which an index rises 10% on the first day and falls 10% on the second day.
An index starting at 100 would rise to 110 after the first day and then fall to 99 after the second day.
Simply multiplying the index’s cumulative return by three would not accurately represent the performance of a daily leveraged ETF.
TQQQ’s returns are compounded based on its daily target. As a result, over periods longer than one day, its cumulative performance can differ significantly from three times the Nasdaq-100’s cumulative return.
ProShares warns that for holding periods longer than one day, TQQQ’s actual return may be higher or lower than its daily target. Factors such as volatility, the magnitude of daily market movements, and the length of the holding period can all affect the outcome.
In other words:
TQQQ is not a “long-term 3x version of QQQ.” It is an ETF designed to target 3x the Nasdaq-100’s daily performance.
5. SQQQ: A Daily Inverse Leveraged Nasdaq-100 ETF
ProShares UltraPro Short QQQ (ticker: SQQQ) takes the opposite approach to TQQQ.
SQQQ seeks to provide -3x the daily performance of the Nasdaq-100 Index, before fees and expenses.
If the Nasdaq-100 rises 10% on a given day, SQQQ’s daily target would be approximately a 30% loss. If the Nasdaq-100 falls 10%, SQQQ’s daily target would be approximately a 30% gain.
SQQQ was also launched on February 9, 2010.
As of 2026, SQQQ has a total expense ratio of 0.99%, with a net expense ratio of 0.95% under the applicable fee waiver arrangement.
SQQQ also resets its exposure daily. As a result, it should not be interpreted as a product that will necessarily deliver three times the Nasdaq-100’s inverse cumulative return over a longer period.
Its objective is -3x the index’s daily performance, not -3x over an extended holding period.
SQQQ can therefore be viewed as a directional trading or hedging tool for investors seeking inverse leveraged exposure to the Nasdaq-100 on a daily basis.
6. QQQ vs. QQQM vs. TQQQ vs. SQQQ: What's the Difference?
The four ETFs represent fundamentally different approaches to Nasdaq-100 exposure.
QQQ: Tracks the Nasdaq-100 and provides approximately 1x exposure to the index.
QQQM: Also tracks the Nasdaq-100 and provides approximately 1x exposure, with a lower expense ratio than QQQ.
TQQQ: Seeks 3x the Nasdaq-100’s daily performance and provides leveraged bullish exposure.
SQQQ: Seeks -3x the Nasdaq-100’s daily performance and provides leveraged inverse exposure.
The two most important distinctions are straightforward.
First, QQQ and QQQM are traditional index ETFs, while TQQQ and SQQQ are leveraged and inverse ETFs.
Second, QQQ and QQQM seek to track the Nasdaq-100 itself, while TQQQ and SQQQ seek to magnify or reverse the index’s performance on a daily basis.
For that reason, comparing the four funds simply by looking at their returns can be misleading. They are designed to serve very different investment purposes.
7. QQQ vs. QQQM: What Should Investors Compare?
For investors seeking traditional Nasdaq-100 exposure, QQQ and QQQM are the most direct comparison.
1. Expense Ratio
As of 2026:
QQQ: 0.18%
QQQM: 0.15%
The difference is 0.03 percentage points.
From an expense perspective alone, QQQM has the lower annual fund cost.
2. Trading Needs
QQQ has a much longer operating history and a highly active trading market.
For investors who place a greater emphasis on secondary-market trading, liquidity, or options-related activity, QQQ’s established market can be an important consideration.
For investors primarily focused on long-term holding costs, QQQM’s lower expense ratio may be more relevant.
The comparison between QQQ and QQQM therefore comes down to factors such as trading needs and long-term costs, rather than simply which ETF has delivered the higher return in the past.
8. TQQQ and SQQQ: Why They Aren't Simply “Amplified” ETFs
When investors first encounter leveraged ETFs, it can be tempting to think of them in very simple terms:
Nasdaq-100 goes up → TQQQ
Nasdaq-100 goes down → SQQQ
This captures the basic daily direction of the two products, but it does not tell the whole story.
Once the holding period extends beyond a single trading day, investors need to consider daily resets and compounding.
For example, during a sustained upward trend, TQQQ’s cumulative performance may differ significantly from three times the Nasdaq-100’s cumulative return.
Likewise, during a prolonged market decline, SQQQ’s cumulative performance cannot simply be calculated as negative three times the Nasdaq-100’s cumulative return.
In a highly volatile, choppy market, repeated daily gains and losses can further increase the difference between the ETFs’ actual cumulative returns and a simple 3x or -3x calculation.
This is one of the most important concepts to understand when comparing leveraged ETFs with traditional index ETFs.
9. How to Think About the Four ETFs
The four ETFs can be viewed as four different tools.
QQQ:
“I want direct exposure to the Nasdaq-100.”
QQQM:
“I also want Nasdaq-100 exposure, but I place more emphasis on long-term holding costs.”
TQQQ:
“I want 3x daily exposure to the upside of the Nasdaq-100 and understand that leverage can significantly increase volatility and risk.”
SQQQ:
“I want -3x daily exposure to the Nasdaq-100 for directional trading or hedging purposes.”
There is no single product that serves all of these objectives.
The key is to understand the investment horizon, market view, risk tolerance, and need for leverage before choosing between them.
10. Three Common Misunderstandings About These ETFs
Misunderstanding 1: TQQQ Will Always Deliver 3x the Nasdaq-100's Long-Term Return
This is one of the most common misconceptions about leveraged ETFs.
TQQQ targets 3x the Nasdaq-100's daily performance, not three times its cumulative long-term return.
Misunderstanding 2: SQQQ Is Simply a Long-Term 3x Short Position on the Nasdaq-100
SQQQ also targets a daily return of -3x.
Over longer holding periods, daily resets and compounding can cause its actual performance to differ substantially from a simple calculation of -3x the index's cumulative return.
Misunderstanding 3: Past Returns Are the Most Important Factor When Comparing These ETFs
Past performance does not change the structure or investment objective of an ETF.
For QQQ and QQQM, investors should focus on factors such as index exposure, expense ratio, and trading needs.
For TQQQ and SQQQ, investors also need to understand daily leverage, daily resets, compounding, and the impact of market volatility.
Conclusion: Understand the Tool Before Choosing the ETF
QQQ, QQQM, TQQQ, and SQQQ are all linked to the Nasdaq-100, but they represent four very different investment tools.
QQQ and QQQM provide traditional Nasdaq-100 exposure. QQQ has a longer operating history and an active trading market, while QQQM has a lower expense ratio.
TQQQ and SQQQ are daily leveraged and inverse ETFs that seek to deliver 3x and -3x the Nasdaq-100’s daily performance, respectively. Their longer-term returns should not be interpreted simply as three times or negative three times the index’s cumulative return.
For investors trying to understand these four ETFs, the most important questions are not simply which one has performed better. Instead, consider:
Am I looking for long-term Nasdaq-100 exposure or short-term directional exposure?
Do I actually need leverage?
Do I understand how daily resets and compounding can affect returns over time?
Understanding these questions is the key to understanding the differences between QQQ, QQQM, TQQQ, and SQQQ.
