Invesco QQQ Trust (QQQ)

The Invesco QQQ Trust (QQQ) delivers unmatched concentration in mega-cap tech, with $290 billion in assets under management tracking the Nasdaq-100. Its heaviest weighting in FANG+ stocks — including Apple, Microsoft, and Nvidia — gives it a 32% higher exposure to the technology sector than the typical S&P 500 ETF. This focus amplifies both growth potential and volatility, making it ideal for aggressive investors: over the past decade, QQQ has outperformed the broad market with a 15.2% annualized return, nearly 5 percentage points ahead of #5 on this list, SPY. Since inception in 1999, it has delivered a cumulative return exceeding 500%, driven by tech innovation.
