Invesco Top QQQ ETF (QBIG) is an actively managed exchange-traded fund that provides exposure to the top companies in the Nasdaq-100 Index, as represented by the Nasdaq-100 Mega Index, comprising approximately the top 45% by weight of Nasdaq-100 companies not exceeding 47%; it invests through a combination of direct equity holdings in select mega-cap securities, total return swaps, and derivatives such as futures contracts. The fund's portfolio is concentrated in high-weighted names including Nvidia, Microsoft, Apple, Amazon, Broadcom, Meta Platforms, Tesla, and Alphabet, with sector allocations dominated by information technology (64%), communication services (18%), and consumer discretionary (17%); it features a total expense ratio of 0.29%, 9 holdings as of mid-2025, and trades on the Nasdaq exchange with creation/redemption in cash creation units of 50,000 shares. Launched on December 4, 2024, and managed by Invesco Ltd., headquartered at 3500 Lacey Road, Suite 700, Downers Grove, Illinois, the ETF targets investors seeking concentrated growth from large-cap, non-financial U.S.-listed companies in the Nasdaq-100 universe, with 100% geographic allocation to the United States. In a key recent development, Invesco launched QBIG as part of the expansion of its QQQ Innovation Suite in December 2024, alongside the Invesco QQQ Low Volatility ETF (QQLV), strengthening its position as the leading provider of Nasdaq-100-based ETFs through a strategic partnership with Nasdaq, Inc., which licenses the underlying Nasdaq-100 Mega Index and enables quarterly rebalancing to adapt to shifts in mega-cap leadership beyond fixed groups like the Magnificent Seven. No subsequent major acquisitions, funding rounds, or operational reorganizations have been reported for the fund as of late 2025, though Invesco broadly announced QQQ structure modernization initiatives in its Q2 2025 earnings to enhance profitability across its ETF lineup.
