The Invesco QQQ ETF provides exposure to many large businesses associated with American innovation, including NVIDIA, Apple, Microsoft, Amazon, Alphabet, and other leaders in semiconductors, cloud computing, artificial intelligence, and digital commerce.
That quality can create a dangerous assumption: because the companies are large and profitable, QQQ must be a sufficiently safe foundation for an entire retirement account.
It is not that simple.
QQQ may be a suitable long-term growth investment for some investors. But investing in QQQ and placing nearly an entire large IRA in QQQ are two very different decisions. The first is a security-selection decision. The second is a portfolio-risk decision.
QQQ is diversified by company but concentrated by economic exposure
QQQ tracks the Nasdaq-100 Index, which holds 100 of the largest nonfinancial companies listed on Nasdaq. On the surface, owning approximately 100 companies sounds diversified.
The weights tell a different story. Based on a September 4, 2026 holdings snapshot:
- The 10 largest positions represented approximately 46% of QQQ.
- The 20 largest positions represented approximately 64.7% of QQQ.
- The remaining holdings collectively represented only about 35.3%.
Alphabet’s Class A and Class C shares are listed as separate positions, but they represent exposure to the same underlying company. More importantly, many of the largest holdings share similar economic drivers: technology spending, semiconductor demand, artificial-intelligence investment, interest rates, and growth-stock valuation multiples.
This means QQQ offers substantial company-level diversification but considerably less diversification across investment styles and economic risk factors. QQQ’s SEC-filed summary prospectus classifies the fund as non-diversified and warns that its value may be more susceptible to adverse developments affecting a single issuer.
What the constituent drawdowns reveal
We calculated the maximum drawdowns of 10 leading QQQ positions using daily adjusted closing prices from September 4, 2020, through September 4, 2026.
| Holding | Maximum drawdown | Peak to trough |
|---|---|---|
| NVIDIA | −66.34% | Nov. 29, 2021–Oct. 14, 2022 |
| Apple | −33.36% | Dec. 26, 2024–Apr. 8, 2025 |
| Microsoft | −37.15% | Nov. 19, 2021–Nov. 3, 2022 |
| Micron | −57.63% | June 18, 2024–Apr. 4, 2025 |
| Amazon | −56.15% | July 8, 2021–Dec. 28, 2022 |
| AMD | −65.45% | Nov. 29, 2021–Oct. 14, 2022 |
| Alphabet Class A | −44.32% | Nov. 18, 2021–Nov. 3, 2022 |
| Alphabet Class C | −44.60% | Nov. 18, 2021–Nov. 3, 2022 |
| Tesla | −73.63% | Nov. 4, 2021–Jan. 3, 2023 |
| Meta Platforms | −76.74% | Sept. 7, 2021–Nov. 3, 2022 |
After normalizing the 10 QQQ weights to represent a portfolio containing only those positions, their weighted-average individual maximum drawdown was approximately 53.5%.
That number is alarming, but it must be interpreted correctly. It is not the historical drawdown of a top-10 portfolio, and it is not a forecast that QQQ will fall 53.5%. Each company reached its maximum drawdown on different dates. A real portfolio combines the daily returns of all its holdings, so diversification and the timing of individual declines matter.
Over the same six-year measurement window, QQQ’s own maximum adjusted-close drawdown was approximately 35.1%, from December 27, 2021, to November 3, 2022. The difference demonstrates that portfolio diversification worked—but it did not prevent a substantial loss.
Could QQQ still decline 50% to 70%?
Yes. A decline of that magnitude remains possible even though today’s largest companies are generally more mature and profitable than many of the speculative businesses associated with the dot-com bubble.
Profitability does not eliminate valuation risk. A stock can decline sharply when earnings weaken, its valuation multiple contracts, or both happen simultaneously. For example, if earnings fall 20% while the valuation multiple contracts by approximately 38%, the combined price decline would be about 50%.
| QQQ drawdown | Illustrative environment |
|---|---|
| −20% to −35% | Growth-stock bear market or valuation correction |
| −35% to −50% | Recession with earnings and multiple compression |
| −50% to −60% | Severe recession, technology bust, or major geopolitical or financial shock |
| −60% to −70% | Extreme systemic crisis or prolonged speculative-bubble collapse |
These are scenarios, not probability forecasts. A 50% decline is a credible severe stress case. A 60% to 70% decline is a lower-probability tail event, but it cannot be dismissed simply because QQQ owns high-quality companies.
During a crisis, correlations between growth companies can rise sharply. Semiconductor demand can weaken at the same time that cloud spending slows, advertising contracts, and investors demand lower valuation multiples. When the same forces affect most of QQQ’s largest positions, its apparent diversification offers less protection.
Why a major drawdown matters more inside an IRA
A long-term investor who is still contributing may have time to wait for recovery and purchase additional shares at lower prices. A retiree withdrawing money faces a different problem.
If withdrawals continue during a major decline, shares must be sold when prices are depressed. Those shares no longer participate in the eventual recovery. This is commonly called sequence-of-returns risk.
Recovery mathematics also becomes increasingly demanding:
- A 35% loss requires a 53.8% gain to recover.
- A 50% loss requires a 100% gain.
- A 60% loss requires a 150% gain.
- A 70% loss requires a 233% gain.
For a $2 million IRA, a 50% decline means a temporary loss of $1 million. Whether the investor can emotionally tolerate that decline is important, but the more important question is whether the retirement plan can financially survive it while continuing required or planned withdrawals.
The dollar size of the account alone does not determine the risk. What matters is the relationship between the account, annual spending, outside income, withdrawal timing, and the investor’s remaining horizon.
Is buying and holding QQQ unwise?
Not necessarily.
The stronger conclusion is that using QQQ as nearly the entire large IRA is an aggressive concentration that should not be treated as a default retirement strategy.
A nearly 100% QQQ allocation may be defensible for an investor who:
- Has decades before withdrawals begin.
- Receives substantial dependable income from other sources.
- Can tolerate a decline of 50% or more without selling.
- Understands and deliberately accepts growth and technology concentration.
- Has sufficient flexibility to reduce spending during a prolonged bear market.
It becomes harder to justify when the investor is approaching retirement, depends on the IRA for essential expenses, would abandon the strategy during a large decline, needs capital stability over the next several years, or already owns substantial technology exposure elsewhere.
A more resilient role for QQQ
An investor does not have to choose between owning no QQQ and holding only QQQ. QQQ can serve as a growth allocation within a portfolio whose other components address different risks.
Depending on the investor’s circumstances, a broader structure could include diversified U.S. equities, international equities, high-quality bonds or U.S. Treasuries, cash or short-term bonds for near-term withdrawals, and a defined rebalancing policy.
This structure will not eliminate losses. Its purpose is to reduce dependence on one market segment and avoid being forced to sell QQQ after a severe decline.
The real question every QQQ investor should ask
The central question is not whether QQQ owns excellent companies today. It does.
If QQQ falls 50% and remains below its previous high for several years, can my retirement plan continue without forcing me to sell?
If the answer is yes, a substantial QQQ allocation may be compatible with the investor’s risk capacity. If the answer is no, the allocation—not necessarily the ETF—is the problem.
QQQ can be a powerful long-term growth vehicle. It should not be confused with a complete retirement plan.
Methodology and sources
Holdings weights are approximate and change daily with market prices and portfolio activity. The top-10 and top-20 concentration figures use a September 4, 2026 holdings snapshot. Maximum drawdowns were calculated from Yahoo Finance daily adjusted closing prices between September 4, 2020, and September 4, 2026. For each price series, drawdown was measured from the highest prior adjusted close to each subsequent adjusted close; the most negative observation is reported.
