QQQ Outperforms S&P 500 Due to Concentration and AI Earnings
Invesco QQQ Trust outpaced the S&P 500 over the past year, driven by heavier weighting in top technology firms and robust earnings growth.
The Invesco QQQ Trust has delivered a 20.67% return over the past year, surpassing the 16.54% gain of the Vanguard S&P 500 ETF. This outperformance extends a decade-long trend where QQQ achieved a 20.64% annualized return compared to 15.44% for its broader market counterpart. As reported by GN stocks/sp500, the divergence stems not from holding different companies, but from how much weight is assigned to the largest non-financial firms.
Both funds hold Nvidia, Apple, and Microsoft as their largest positions, but QQQ allocates significantly more capital to these leaders. The top ten holdings in QQQ constitute 47.14% of its assets, whereas they make up only 37.62% of the Vanguard fund. This structural difference means QQQ is a more concentrated bet on high-growth technology, excluding financial institutions entirely from its index composition.
Concentration Drives Performance Gap
QQQ’s index focuses on the 100 largest non-financial companies listed on the Nasdaq, resulting in higher exposure to semiconductor and AI infrastructure leaders like Micron Technology and Advanced Micro Devices. The Vanguard fund, holding over 500 stocks, includes financial giants like JPMorgan Chase and Berkshire Hathaway, which dilute the growth profile. The absence of banks in QQQ removes slower-growing sectors, amplifying the impact of technology earnings on total returns.
Nasdaq-100 companies reported approximately 75% year-over-year earnings growth in the second quarter, marking a 13th consecutive quarter of double-digit expansion. While some of this growth is inflated by one-time gains such as Alphabet’s unrealized SpaceX stake and Amazon’s Anthropic-related income, the core trend remains strong. Even excluding these outliers, the S&P 500’s growth rate drops to 32%, highlighting the persistent earnings advantage of the tech-heavy index.
Valuation Premium Remains Modest
Despite the superior earnings growth, the valuation premium for QQQ is relatively small. The fund trades at approximately 29.5 times earnings, compared to 27 times for the Vanguard S&P 500 ETF. This 9% premium reflects market confidence in the continued dominance of large-cap technology firms. The lower expense ratio of the Vanguard fund, at 0.03% versus 0.18% for QQQ, is negligible when measured against the historical return differential.
Market Rotation Risks Persist
Recent market dynamics have shown that broader indices can outperform during periods of skepticism regarding AI profitability. In July, the S&P 500 Equal Weight Index beat the Nasdaq-100 by 7.5 percentage points, the widest margin since 2005. The Nasdaq-100 experienced an 11.3% drawdown from its peak before recovering, indicating that concentration carries higher volatility risk.
Over the last five years, QQQ’s annualized return of 14.11% still leads the S&P 500’s 12.85%, but the margin has narrowed to 1.3 percentage points. This period included the 2022 bear market, which disproportionately affected large-cap tech stocks. For the S&P 500 to outperform QQQ in the next five years, AI-driven earnings would need to disappoint significantly, or capital would need to rotate decisively into slower-growing financial and industrial sectors.
