What's inside
VOO tracks the S&P 500, offering exposure to 505 companies. Its largest positions are NVIDIA (NASDAQ:NVDA), Microsoft (NASDAQ:MSFT), and Apple (NASDAQ:AAPL), each accounting for around 0.07%–0.08% of the fund. With over 15 years on the market, VOO seeks to mirror the performance of the U.S. large-cap landscape, minimizing concentration risk.
In contrast, QQQ follows the NASDAQ-100, which results in a much heavier technology tilt (54%), with communication services and consumer cyclical stocks making up another 29%. Its top holdings, NVIDIA, Microsoft, and Apple are the same but they carry slightly more weight in QQQ than in VOO. QQQ's focus on 101 companies means less diversification and greater exposure to tech sector swings.

Foolish take
The Invesco QQQ Trust, Series 1 ETF may be less diversified than the Vanguard 500 Index Fund ETF but this hasn't mattered to investors in recent years. Fear of missing out on the artificial intelligence revolution has been a tremendous tailwind for the tech stocks the Invesco QQQ Trust follows most closely.
Over the past three years, the Vanguard 500 Index Fund ETF delivered an 80.6% return or 88.6% if you included dividend payments. That's a terrific three-year return, but it pales in comparison to the Invesco QQQ Trust's performance. Over the same time frame, it delivered a 130.8% gain, or 135.3% if you add up dividend payments.
While the past few years have been terrific ones for the Invesco QQQ Trust, stocks in the index appear generally overpriced. The average stock in the Nasdaq 100 index has been trading for 33.25 times trailing 12-month earnings.
