QQQ vs. IWO: Big Tech Dominance or Small-Cap Potential?
The Invesco QQQ Trust (QQQ +1.37%) and iShares Russell 2000 Growth ETF (IWO +2.37%) differ most in market cap focus and sector allocation—QQQ leans into large-cap tech, while IWO broadens exposure to small-cap growth, with IWO charging a modestly higher expense ratio.
Both QQQ and IWO offer exposure to U.S. growth equities, but their approaches diverge sharply: QQQ tracks the tech-heavy Nasdaq-100, favoring established giants, while IWO taps into the Russell 2000 Growth Index for small-cap growth opportunities. This comparison looks at cost, performance, risk, and portfolio makeup to help clarify which may appeal for different objectives.

IWO comes with a slightly higher expense ratio than QQQ, making QQQ more affordable for long-term holders. Both funds offer a modest 0.4% yield, so neither stands out for income-seeking investors.
Performance & risk comparison
| Metric | QQQ | IWO |
|---|---|---|
| Max drawdown (5 y) | -35.12% | -40.51% |
| Growth of $1,000 over 5 years | $1,947 | $1,198 |
IWO has experienced a deeper five-year maximum drawdown than QQQ, reflecting higher risk, and delivered significantly less growth over the past five years despite a recent one-year performance edge. This highlights the more volatile nature of small-cap growth stocks compared to large-cap tech leaders.

What’s inside
IWO tracks small-cap U.S. companies with growth characteristics, holding over 1,100 stocks—far broader than many growth ETFs. Its sector mix skews toward healthcare (25%), technology (22%), and industrials (21%), with top positions like Bloom Energy (BE 3.39%), Credo Technology Group (CRDO 3.66%), and Fabrinet (FN +2.32%), none exceeding a 3% weight. With a fund age of nearly 26 years, IWO offers seasoned exposure to the small-cap growth space.
QQQ, in contrast, concentrates on large, established U.S. companies, with more than half the portfolio in technology and notable weights in communication services and consumer cyclicals. Its top holdings—Nvidia (NVDA +1.30%), Apple (AAPL +3.17%), and Microsoft (MSFT +1.87%)—dominate the fund, lending it a pronounced megacap tilt and less diversification by number of holdings compared to IWO.

What this means for investors
Both QQQ and IWO are built around growth, but they pursue it at opposite ends of the market cap spectrum. QQQ tracks the 100 largest non-financial companies on the Nasdaq, a concentrated bet on megacap technology dominance, with roughly 50% in tech alone and household names like Nvidia, Apple, and Microsoft carrying outsized weight. IWO tracks the Russell 2000 Growth Index, spreading over 1,100 small-cap growth stocks across healthcare, industrials, and technology in roughly equal measure, with no single holding above 3%.
The scale difference is striking. QQQ manages around $375 billion; IWO manages roughly $12 billion. QQQ’s companies are global giants with established revenue streams. IWO’s companies are earlier-stage businesses with more room to grow — and more room to stumble.
QQQ charges a slightly lower fee than IWO, but the more meaningful cost is volatility. Small-cap growth stocks historically experience sharper swings than their large-cap counterparts. QQQ is the high-conviction tech wager, while IWO is the diversified small-cap growth bet for investors willing to accept a rougher ride for potentially higher long-term rewards.
