TQQQ, QQQ, VOO, and SPY are among the most widely followed U.S. equity ETFs. They represent fundamentally different strategies: TQQQ is a 3x leveraged bet on the Nasdaq-100; QQQ tracks the Nasdaq-100 without leverage; VOO and SPY both track the S&P 500. Choosing the right one depends on your time horizon, risk tolerance, and investment goals.
This article provides a comprehensive comparison of long-term performance, risk exposure, sector concentration, expense ratios, and volatility behavior across bull markets, sideways markets, and downturns. We explain how leveraged ETFs like TQQQ behave differently from traditional index ETFs and how to determine which strategy aligns best with your long-term portfolio goals in 2026.
At-a-Glance: TQQQ vs QQQ vs VOO vs SPY
| ETF | Index | Leverage | Expense Ratio | Best For | Long-Term Hold? |
|---|---|---|---|---|---|
| TQQQ | Nasdaq-100 | 3x daily | 0.88% | Short-term traders only | No — SEC warns |
| QQQ | Nasdaq-100 | 1x | 0.18% | Growth/tech tilt | Yes |
| VOO | S&P 500 | 1x | 0.03% | Low-cost core holding | Yes |
| SPY | S&P 500 | 1x | 0.09% | Active traders; options | Yes |

Understanding Leveraged vs. Non-Leveraged ETFs
TQQQ: The 3x Daily Reset Trap
ProShares UltraPro QQQ (TQQQ) seeks to deliver three times the daily returns of the Nasdaq-100 Index. It uses derivatives and debt to amplify gains and losses. The critical issue: TQQQ resets its leverage daily, not annually. Per SEC guidance, “performance over a period longer than one day can differ significantly from their stated daily performance objectives” — and the SEC gives a striking example: “An ETF seeking to deliver three times the daily return of a different index fell 53 percent, while the underlying index actually gained around 8 percent.”
This phenomenon is called volatility decay. Per CFA Institute, as volatility increases, compound returns decrease; leveraged ETFs deliver “at least twice the risk of the index but less than twice the return” over extended periods. AInvest documented a case where the Nasdaq gained 3.44% but TQQQ gained only 9.79% instead of ~10.3% — a daily tracking deficit. In choppy markets, TQQQ can lose value even when the index moves sideways.
The Motley Fool and Proactive Advisor conclude leveraged ETFs do not belong in long-term portfolios. When QQQ suffered a 37% drawdown from November 2021, TQQQ experienced an 82% drawdown and would have needed a 450% gain to break even. Yahoo Finance data show TQQQ fell 79% in 2022, then rallied 198% in 2023 and 58% in 2024 — extreme volatility unsuitable for buy-and-hold.
QQQ: Traditional Nasdaq-100 Exposure
Invesco QQQ Trust (QQQ) tracks the Nasdaq-100 Index — the 100 largest non-financial companies listed on Nasdaq. It is technology-heavy: per SlickCharts, the top three holdings are Nvidia (13%), Apple (11%), and Microsoft (9%) — about 33% in three stocks. Nasdaq reports the index is approximately 59% technology by sector. QQQ has an expense ratio of 0.18%, per CompaniesMarketCap. It is designed for long-term holding and has delivered strong returns: over 18 years (2007–2025), the Nasdaq-100 returned 1,342% cumulative (16% annualized) vs. the S&P 500’s 560% (11% annualized), per Investopedia.
VOO vs SPY: Two S&P 500 Giants
Both Vanguard S&P 500 ETF (VOO) and SPDR S&P 500 ETF Trust (SPY) track the S&P 500. They deliver nearly identical performance. The key difference: expense ratio. VOO charges 0.03%; SPY charges 0.09% — three times more, per The Motley Fool and Morningstar. Over 30 years, a 0.06% fee difference can cost tens of thousands of dollars on a $100,000 portfolio, per ICFS.
Morningstar rates VOO Gold and SPY Silver. SPY operates as a unit investment trust, which prevents dividend reinvestment and securities lending — small structural disadvantages. SPY’s advantage: superior liquidity and the world’s most active options market, per Nasdaq. For active traders and options users, SPY may be preferable. For long-term buy-and-hold, VOO wins on cost. VOO became the first ETF to cross $700 billion in assets in 2025 and held ~$861 billion as of early 2026, per AAII.
Index Exposure: Nasdaq-100 vs S&P 500
The Nasdaq-100 and S&P 500 are different indices. The Nasdaq-100 includes the 100 largest non-financial Nasdaq-listed companies — heavily weighted to technology, consumer discretionary, and healthcare. The S&P 500 includes 500 large-cap U.S. companies across all sectors, with broader diversification. Per Nasdaq, the Nasdaq-100’s annualized volatility is 22.9% vs. the S&P 500’s 20.1%; daily return correlation is 93%. The Nasdaq-100 outperformed in 14 of 18 years (2007–2025) but carries higher risk. Morningstar notes substantial overlap — both are dominated by mega-cap tech (Microsoft, Apple, Alphabet) — so owning both QQQ and VOO may not add much diversification.
| Index | Holdings | Sector Concentration | Volatility (Ann.) | 18-Year Return (2007–2025) |
|---|---|---|---|---|
| Nasdaq-100 | 100 non-financial | ~59% tech | 22.9% | 1,342% (16% CAGR) |
| S&P 500 | 500 large-cap | Diversified | 20.1% | 560% (11% CAGR) |
Long-Term Performance and Volatility Comparison
| ETF | 2022 Return | 2023 Return | 2024 Return | YTD 2026 (Est.) | 5Y Ann. Volatility |
|---|---|---|---|---|---|
| TQQQ | -79% | +198% | +58% | -8% to -10% | ~62% |
| QQQ | -33% | +55% | +19% | -2% to -3% | ~23% |
| VOO | -18% | +26% | +24% | ~0% to +0.5% | ~18% |
| SPY | -18% | +26% | +24% | ~-0.2% | ~18% |
Sources: Yahoo Finance, YCharts, FinanceCharts. TQQQ 2022 drawdown per Yahoo; volatility per YCharts. Past performance does not guarantee future results.
TQQQ’s 2022 collapse illustrates the risk: a 79% loss in one year. Even after 198% and 58% rebounds in 2023–2024, TQQQ can give back gains rapidly in choppy conditions. As of March 2026, TQQQ was down 8–10% YTD while QQQ was down only 2–3%, per AInvest and NPI Fund — volatility decay in action. VOO and SPY, tracking the S&P 500, delivered 16–17% over trailing 12 months as of early 2026, per TipRanks.
Expense Ratios: The Hidden Cost of Long-Term Investing
Expense ratios compound over time. Per ICFS, with $100,000 earning 7% annually over 30 years, a 1% expense ratio vs. 0.10% costs approximately $165,800 in lost wealth. At 1.5%, investors forfeit 32.7% of potential ending wealth. TQQQ’s 0.88% expense ratio (per Investopedia) compounds with volatility decay — a double drag. VOO at 0.03% costs $3 per $10,000 per year; TQQQ at 0.88% costs $88. Over 30 years, that difference is enormous.
| ETF | Expense Ratio | Cost per $10,000/Year | 30-Year Impact (7% return, $100K) |
|---|---|---|---|
| VOO | 0.03% | $3 | Lowest |
| SPY | 0.09% | $9 | Moderate |
| QQQ | 0.18% | $18 | Moderate |
| TQQQ | 0.88% | $88 | High — plus volatility decay |
Which ETF Fits Your Investor Profile?
Long-term retirement investors (IRA, 401k): Morningstar and 24/7 Wall St recommend VOO or a total market ETF (VTI) for core holdings. The Motley Fool highlights VOO’s ultra-low cost for retirement. Avoid TQQQ in retirement accounts — the SEC and every major source warn against long-term leveraged ETF holding.
Growth-focused investors: QQQ offers tech tilt with manageable risk. Per 24/7 Wall St, a two-ETF strategy pairing SCHD (dividends) with QQQ (growth) can work for balanced growth and income. QQQ has delivered 20.5% annualized in some periods.
Active traders: SPY offers the deepest options liquidity. TQQQ may be used for short-term tactical bets, but ProShares and the SEC explicitly state it is not for buy-and-hold.
Diversified portfolio builders: A Bogleheads-style 3-fund portfolio uses VTI (U.S. total market), VXUS (international), and BND (bonds). VOO can substitute for VTI as the U.S. large-cap core. Per The Motley Fool, a 60/20/20 split (60% U.S. stocks, 20% international, 20% bonds) works for beginners.
Best Brokers to Buy ETFs in 2026
All major brokers offer commission-free ETF trading. Per NerdWallet and Investopedia:
- Fidelity — Best overall for ETFs: $0 commissions, 2,500+ ETFs, 90+ screening criteria, excellent research.
- Charles Schwab — 4.8/5 rating, 2,400+ funds, strong ETF screening; best for beginners per Investopedia.
- Vanguard — $0 trades, no minimum; best for experienced buy-and-hold investors who prefer Vanguard’s own ETFs.
- E*TRADE — Commission-free; best for pre-built ETF portfolios.
- Interactive Brokers — Best for advanced traders and global ETF access.
MarketWatch and Benzinga provide additional broker comparisons. All three leaders (Fidelity, Schwab, Vanguard) offer zero-commission ETF trading and no account minimums.
Best ETF Portfolio Allocation for 2026
Per AlphaEx Capital and AllInvestView, a simple low-cost portfolio can be built with 2–3 ETFs:
| Strategy | Allocation | ETFs | Expense Range |
|---|---|---|---|
| 60/40 Balanced | 60% U.S. stocks, 40% bonds | VOO or VTI + BND | 0.03–0.05% |
| 3-Fund Bogleheads | 60% U.S., 25% intl., 15% bonds | VTI + VXUS + BND | 0.03–0.07% |
| Growth Tilt | 70% U.S. growth, 30% bonds | QQQ + BND | 0.10–0.18% |
| Core-Satellite | 80% core, 20% satellite | VOO + sector ETFs | 0.03–0.15% |
Rebalance annually when allocations drift 5% from target. Limit any single ETF to a reasonable percentage of the portfolio; avoid TQQQ in core allocations.
Which ETF Is Best for Retirement Accounts (IRA or 401k)?
For IRAs and 401(k)s, VOO, VTI, or VT are top choices. Morningstar recommends VOO, VT (total world), and IUSB (bonds) for IRA diversification. The Motley Fool cites VT as a single-ETF option for maximum diversification. 24/7 Wall St suggests a 3-ETF portfolio: VTI (60%), IWDA (25%), SCHB (15%).
QQQ can complement a core S&P 500 or total market holding for growth tilt, but it adds concentration risk. TQQQ should never be held long-term in retirement accounts — the SEC, ProShares, and every major financial publication warn against it. Tax-advantaged accounts do not change the fundamental risk of volatility decay.
Volatility and Drawdown Analysis
Per YCharts, TQQQ’s 5-year annualized standard deviation is ~62%; beta is ~3.5x the market. When QQQ fell 37% from its 2021 peak, TQQQ fell 82%. 24/7 Wall St notes TQQQ holders face volatility decay risk “that has nothing to do with the Nasdaq falling” — choppy sideways markets can grind the fund down. Historical analysis cited by The Motley Fool shows a hypothetical 3x QQQ from 1999 would have experienced a 99.96% decline from 2000–2009.
Historical 10-Year Return Comparison
Long-term performance data helps contextualize the trade-offs. Per FinanceCharts, VOO delivered a 306% total return from 2016–2025 with a 15.31% compound annual growth rate. Total Real Returns shows SPY and VOO tracking nearly identically over long periods. QuantFlowLab illustrates that a $10,000 investment in VOO from 2016–2025 grew to approximately $39,747 with no additional contributions, or $98,583 with $200 monthly contributions. TQQQ has no meaningful 10-year comparison because it was launched in 2010 and its structure makes long-term returns unpredictable — in some periods it vastly outperforms; in others it collapses. Options Trading IQ and PortfoliosLab provide side-by-side performance tools for those comparing TQQQ and QQQ over various windows.
Sector Concentration: Why It Matters
QQQ and TQQQ are heavily concentrated in technology. Per SlickCharts, the top five Nasdaq-100 holdings — Nvidia, Apple, Microsoft, Amazon, and Meta — represent a significant portion of the index. When tech corrects, QQQ and TQQQ suffer more than the S&P 500. VOO and SPY, by contrast, hold 500 stocks across 11 sectors, with technology at roughly 28% — still substantial but less concentrated. The Motley Fool notes that in early 2026, concerns about AI valuations caused the Nasdaq-100 to trade sideways while the S&P 500 held up slightly better. For investors seeking diversification, VOO or SPY reduce single-sector risk. For those bullish on tech long-term, QQQ offers targeted exposure — but with the understanding that concentration amplifies both gains and losses.
Practical Allocation Examples for Different Goals
Conservative retiree (age 60+): 50% VOO, 30% BND (bonds), 20% VXUS (international). Focus on capital preservation and income. Avoid TQQQ entirely; limit QQQ to 5–10% if desired for growth tilt.
Moderate investor (age 40–50): 50% VOO, 20% QQQ, 20% VXUS, 10% BND. Balances S&P 500 core with tech tilt and international diversification. Rebalance annually.
Aggressive growth (age 25–35): 60% VOO, 25% QQQ, 15% VXUS. Higher equity allocation; no bonds if risk tolerance permits. Still no TQQQ — use QQQ for growth, not leveraged products.
Beginner with $1,000: Per The Motley Fool, start with a single ETF like VOO or VTI. Add VXUS and BND as the portfolio grows. Million Dollar Journey and AllInvestView provide simple low-cost diversified ETF portfolio templates for 2026.
Expense Ratio Impact: A Concrete Example
Per Model Investing and ICFS, the impact of expense ratios compounds dramatically. Consider a $100,000 investment earning 7% annually for 30 years. At 0.03% (VOO), you keep nearly all of the growth. At 0.09% (SPY), you lose a small amount. At 0.88% (TQQQ), the fee drag is substantial — and that is before accounting for volatility decay, which can erase gains regardless of fees. ICICI Direct notes that a 0.50% difference compounds to significant losses over 20 years. Trade That Swing emphasizes that low fees alone do not guarantee performance — but high fees virtually guarantee underperformance over time. For TQQQ, the 0.88% expense ratio is the least of an investor’s worries; the structural volatility decay is the primary risk.
SEC and Regulatory Warnings on Leveraged ETFs
The SEC’s Updated Investor Bulletin on Leveraged and Inverse ETFs (August 2023) states clearly: “Leveraged and inverse ETFs typically are designed to achieve their stated performance objectives on a daily basis.” The SEC warns that “performance over a period longer than one day can differ significantly” and that investors “can suffer significant losses even if the long-term performance of the index showed a gain.” The bulletin includes a hypothetical example: over two days, a 2x leveraged ETF can lose 4x the index’s two-day return instead of 2x, due to daily reset mechanics. Reuters reported in 2009 that the SEC warned investors on leveraged ETF holdings. AInvest reported that in December 2025, the SEC blocked proposed 3x to 5x leveraged ETFs from Direxion and ProShares, citing Rule 18f-4 violations. Bloomberg reported the SEC instructed fund trustees not to activate registration of these products in March 2026. The regulatory stance is clear: leveraged ETFs are not suitable for buy-and-hold investors.
| ETF | Max Drawdown (2022) | 5Y Volatility | Beta | Recovery Needed (82% loss) |
|---|---|---|---|---|
| TQQQ | ~79% | ~62% | ~3.5x | 450% gain to break even |
| QQQ | ~33% | ~23% | ~1.1x | 49% gain |
| VOO | ~18% | ~18% | 1.0x | 22% gain |
| SPY | ~18% | ~18% | 1.0x | 22% gain |
Methodology: How We Compared These ETFs
We evaluated TQQQ, QQQ, VOO, and SPY using data from more than 30 sources, including: ProShares, Invesco, Vanguard, State Street (issuer websites); SEC, FINRA (regulatory guidance); CFA Institute, Investopedia, The Motley Fool, Morningstar, NerdWallet, Bankrate (editorial and research); Yahoo Finance, YCharts, FinanceCharts, Nasdaq (performance data); Nasdaq, SlickCharts (index composition); ICFS, Model Investing (expense ratio impact); 24/7 Wall St, TipRanks, AlphaEx Capital, AllInvestView, Benzinga, MarketWatch (portfolio and broker recommendations). We weighted regulatory warnings (SEC, FINRA) for leveraged ETF risk; issuer prospectuses for structural details; and third-party performance data for returns and volatility. All figures reflect data available as of March 2026.
Frequently Asked Questions
Is TQQQ good for long-term investing?
No. The SEC, Investopedia, The Motley Fool, and ProShares all warn that TQQQ is designed for daily performance, not long-term holding. Volatility decay can cause significant losses even when the Nasdaq gains.
QQQ vs VOO long-term returns — which wins?
Over 18 years (2007–2025), the Nasdaq-100 returned 1,342% (16% CAGR) vs. the S&P 500’s 560% (11% CAGR), per Investopedia. QQQ outperformed but with higher volatility. Past performance does not guarantee future results.
SPY vs VOO: which is better for retirement?
Morningstar rates VOO Gold and SPY Silver. VOO’s 0.03% expense ratio vs. SPY’s 0.09% makes VOO the better choice for long-term retirement investing. SPY may be preferred for active traders who use options.
What is the best ETF for beginners?
Investopedia recommends Charles Schwab for beginners. For the ETF itself, VOO or VTI offer low-cost, diversified exposure. Avoid TQQQ and other leveraged ETFs.
How do I build a low-cost ETF portfolio?
Use a 3-fund approach: VTI (U.S. stocks) + VXUS (international) + BND (bonds). Allocate 60/20/20 or adjust by age. Rebalance annually. Per The Motley Fool, this approach requires minimal maintenance.
Can I hold both QQQ and VOO?
Yes, but Morningstar notes substantial overlap — both are dominated by mega-cap tech (Microsoft, Apple, Alphabet). Owning both adds concentration rather than diversification. If you want tech tilt, consider 70% VOO + 30% QQQ; if you want pure diversification, VOO alone or VTI is sufficient.
What is volatility decay and why does it hurt TQQQ?
Volatility decay occurs because TQQQ resets its 3x leverage daily. When the market oscillates up and down, the math of compounding works against you: a 10% drop followed by an 11.1% gain does not break even for a 3x fund — you need a larger gain to recover. CFA Institute explains that as volatility increases, compound returns decrease. In choppy sideways markets, TQQQ can lose value even when QQQ is flat.
Decision Framework: Which ETF Should You Choose?
Use this simple framework to narrow your choice:
Step 1 — Define your holding period. If you plan to hold for more than one day, eliminate TQQQ. The SEC, ProShares, and every major financial source advise against it. TQQQ is for intraday or very short-term tactical trades only.
Step 2 — Choose your index. Do you want S&P 500 (broader, 500 stocks) or Nasdaq-100 (tech-heavy, 100 stocks)? S&P 500 = VOO or SPY. Nasdaq-100 = QQQ.
Step 3 — Optimize for cost or liquidity. For S&P 500: VOO (0.03%) wins on cost for long-term holders; SPY (0.09%) wins on liquidity and options depth for active traders. For most buy-and-hold investors, VOO is the better choice.
Step 4 — Consider combining. A core-satellite approach: 70% VOO (core) + 20% QQQ (growth satellite) + 10% bonds or international. Adjust percentages based on risk tolerance and time horizon.
How to Build a Low-Cost ETF Portfolio in 2026
Per AllInvestView, the Bogleheads 3-fund portfolio remains a proven strategy: VTI (U.S. total market), VXUS (international), and BND (bonds). You can substitute VOO for VTI as the U.S. large-cap core — the performance difference is minimal since the S&P 500 represents about 80% of the U.S. market by cap. AlphaEx Capital recommends rebalancing quarterly with a 5% drift tolerance, prioritizing expense ratios under 0.10%, and limiting any single ETF to a reasonable percentage of the portfolio. Active Calculator and FINRA’s Fund Analyzer (cited by the SEC) can help you estimate the true cost of fees over time. The key principle: keep costs low, diversify broadly, and hold for the long term. Avoid the temptation to chase TQQQ’s bull-market returns — the drawdowns can be devastating.
Bottom Line: Match the ETF to Your Goals
For long-term investors: VOO or SPY for S&P 500 exposure; QQQ for tech tilt. VOO wins on cost for buy-and-hold. Avoid TQQQ for any holding period beyond a day — the SEC, CFA Institute, and every major source agree.
For active traders: SPY offers superior options liquidity. TQQQ may be used for short-term tactical bets only, with full awareness of volatility decay.
For retirement: VOO, VTI, or VT as core; add bonds (BND) and international (VXUS) for diversification. Rebalance annually. The 4% safe withdrawal rule suggests a $500,000 portfolio can generate approximately $20,000 annually while preserving principal — per AlphaEx Capital. Build that portfolio with low-cost index ETFs, not leveraged products.
Next steps: Open an account at Fidelity, Schwab, or Vanguard; choose your core ETF (VOO or VTI); add international and bonds if desired; invest regularly and hold. Do not chase TQQQ’s bull-market gains — the drawdowns can wipe out years of returns. Set up automatic contributions if possible; dollar-cost averaging reduces the impact of market timing. Review your allocation annually and rebalance when drift exceeds 5%. For retirement accounts, maximize tax-advantaged contributions before investing in taxable brokerage accounts.
