- The RBB Fund, Inc. operates as a Maryland-domiciled open-end investment management company and the first organized multiple series trust, providing turnkey platform services for exchange-traded funds (ETFs) and mutual funds, including establishment, servicing, and corporate governance to enable investment advisors to focus on asset management. Founded in 1988 and headquartered in Lutherville Timonium, Maryland, the company oversees more than $23 billion in assets across over 60 fund offerings from 13 investment advisors and more than 20 unaffiliated subadvisors, with primary operations in the United States. Among its series is the Motley Fool Innovative Growth Factor ETF (MFIG), a passively managed ETF that seeks to track the total return performance (before fees and expenses) of the Motley Fool Innovative Growth Index through investments in equity securities exhibiting rapid profitability growth, innovation metrics including gross profit growth and acceleration, and future growth potential via a proprietary Innovative Growth Composite Score; the fund maintains approximately 150 holdings, applies tax diversification adjustments to limit individual position weights (no more than 24% per holding, with positions over 4.8% not exceeding 48% cumulatively), and charges a 0.50% expense ratio.
RBB Fund supports a broad range of passive and active strategies across U.S. large-cap, mid-cap, small-cap, and global equities, targeting institutional and retail investors seeking diversified exposure to growth, value, momentum, and capital efficiency factors; geographic focus remains predominantly on U.S.-traded securities, including American Depositary Receipts for international companies listed on U.S. exchanges. Motley Fool Asset Management, LLC serves as investment adviser for MFIG and related series, leveraging methodologies developed by The Motley Fool, LLC's Investing Intelligence team.
In recent developments, RBB Fund completed mutual fund-to-ETF conversions for two Motley Fool-advised strategies, enhancing tax efficiency and liquidity for investors. On December 9-10, 2025, Motley Fool Asset Management launched MFIG alongside the Motley Fool Value Factor ETF (MFVL) and Motley Fool Momentum Factor ETF (MFMO) under the RBB Fund umbrella as part of a major expansion, introducing systematic index-based products reflecting evidence-based investing principles with composite factor scores; this follows September 2025 announcements of plans for 15 additional ETFs and builds on Motley Fool's existing six ETFs managing over $2.5 billion, including the flagship Motley Fool 100 Index ETF (TMFC) at $1.9 billion in assets. These launches mark RBB Fund's continued growth in the competitive ETF marketplace, supporting boutique advisors like Motley Fool amid industry trends toward factor-focused and tax-optimized vehicles.
