Should You Buy the Invesco QQQ ETF During the Stock Market Sell-Off? History Offers a Clear Answer.

Key Points
The Nasdaq-100 hosts the 100 most valuable nonfinancial companies listed on the Nasdaq stock exchange, with around 60% of its portfolio parked in technology stocks.
The index is down almost 7% from its record high amid rising economic uncertainty and geopolitical tensions.
The Invesco QQQ ETF tracks the performance of the Nasdaq-100, and history suggests there is rarely a bad time to buy it.

Over 3,500 companies have chosen to go public through the Nasdaq stock exchange. The Nasdaq-100 index tracks the performance of the top 100 (by value) companies, excluding banks and other financial institutions.
Since the technology sector is home to more trillion-dollar companies than any other sector, it boasts a dominant weighting of almost 60% in the Nasdaq-100. That means companies at the cutting edge of industries like artificial intelligence (AI) have a significant influence over the performance of the index, which is why it typically delivers higher returns than more diversified indexes like the S&P 500.

But that can also be a recipe for volatility. The Nasdaq-100 is currently trading down 8.8% from its all-time high amid rising economic uncertainty and geopolitical tensions, whereas the S&P 500 has declined by a lesser 7%.
The Invesco QQQ Trust (NASDAQ: QQQ) is an exchange-traded fund (ETF) that tracks the performance of the Nasdaq-100 by holding the same stocks and maintaining similar weightings. Is the recent sell-off a buying opportunity for investors? Here's what history says.
Tech stocks tend to lead the market higher
The Nasdaq-100 (and by extension, the Invesco QQQ ETF) invests across 10 different economic sectors, but as I mentioned earlier, almost 60% of the value of its entire portfolio is parked in technology stocks. The tech sector is home to five companies valued at $1 trillion or more, and four of them are among the top holdings in the Nasdaq-100:
- Nvidia: $4.2 trillion
- Apple: $3.64 trillion
- Microsoft: $2.84 trillion
- Taiwan Semiconductor Manufacturing: $1.71 trillion (not in the Nasdaq-100, because it's listed on the New York Stock Exchange)
- Broadcom: $1.47 trillion
Over the last decade, Nvidia, Apple, Microsoft, and Broadcom have delivered an eye-popping median return of 1,400%. They contributed to a 452% return in the Nasdaq-100 over that period, which was twice the return of the S&P 500.
The Nasdaq-100 also holds large positions in other trillion-dollar giants like Alphabet, Amazon, Tesla, and Meta Platforms. They don't fall into the tech sector specifically, but they are extremely active in emerging industries like artificial intelligence (AI), and their respective stocks have also delivered blistering returns over the last decade.
There are many up-and-coming stocks that could also help drive the Nasdaq-100 higher over the long term:
- Advanced Micro Devices, which competes with Nvidia in the market for AI data center chips.
- Micron Technology, which supplies data center memory hardware to both Nvidia and AMD
- Palantir Technologies, which developed a series of AI-powered software platforms to help organizations extract maximum value from their internal data.
- Netflix, which operates the world's largest streaming service for movies and television shows.
- CrowdStrike, which developed an AI-powered, all-in-one cybersecurity platform for enterprises.
There is rarely a bad time to invest
Volatility is a normal part of the investing journey. Enduring stock market declines is the price of admission for an opportunity to earn significant returns over the long term. The Nasdaq-100 has experienced five bear markets since the Invesco QQQ ETF was established in 1999, which are defined by peak-to-trough declines of 20% or more.
Each bear market was caused by an entirely different event, like the bursting of the dot-com bubble in the year 2000, the global financial crisis in 2008, the COVID-19 pandemic in 2020, the inflation crisis in 2022, and the Trump administration's "Liberation Day" tariffs in 2025. In other words, it's practically impossible to predict when the stock market might slip into bear territory, so staying the course -- even during the most unsettling periods -- is the secret to success.
In fact, the Invesco ETF has still produced a compound annual return of 10.3% since 1999, even after accounting for every sell-off, correction, and bear market along the way. Plus, returns have accelerated to 20.3% per year over the last decade thanks to incredible growth in industries like cloud computing and AI. Therefore, investors who simply stayed in the market over the last 27 years would have done exceptionally well.
AI stocks are likely to continue driving the broader market higher, and with technologies like robotics, autonomous vehicles, and even quantum computing quickly gaining momentum, it's reasonable to expect the Invesco QQQ ETF to trend higher over the long term. As a result, now might be a great time to buy.
