景順ＱＱＱ Hisse Grafiği

QQQ is one of the most established and actively traded ETFs in the world. Per the rules of its index, the fund only invests in nonfinancial stocks listed on NASDAQ, and effectively ignores other sectors too, causing it to skew massively away from a broad-based large-cap portfolio. QQQ has huge tech exposure, but it is not a 'tech fund' in the pure sense either. The fund's arcane weighting rules further distance it from anything close to plain vanilla large-cap or pure-play tech coverage. The ETF is much more concentrated in its top holdings and is more volatile than our vanilla large-cap benchmark. Still, the fund has huge name recognition for the underlying index, the NASDAQ-100. In all, QQQ delivers a quirky but wildly popular mash-up of large-cap growth exposure. The fund and index are rebalanced quarterly and reconstituted annually. Prior to December 22, 2025, the fund was one of just a few that had operated as a unit investment trust. Modernizing into the more commonly used open-end fund structure provides greater operational flexibility in terms of securities lending and reinvesting any income.
