The RBB Fund, Inc. - F/m Opportunistic Income ETF (ZHOG) operates as an actively managed exchange-traded fund focused on opportunistic fixed income investments. The fund seeks current income and capital appreciation through a flexible portfolio that includes high-yield corporate bonds, mortgage-backed securities, asset-backed securities, bank loans, and opportunistic allocations to emerging market debt and structured credit products; it employs a bottom-up research process emphasizing undervalued securities with strong risk-adjusted return potential. ZHOG targets institutional and retail investors seeking enhanced yield in varying interest rate environments, with geographic operations spanning U.S. and select international fixed income markets. Established under The RBB Fund, Inc., the fund is headquartered in Rye Brook, New York, and managed by F/m Investments, with the ETF listed on major U.S. exchanges. In late 2025, F/m Investments launched the ZHOG ticker as part of an expansion of its ETF suite via the provided fund platform at fmetfs.com, marking a strategic shift toward broader opportunistic income strategies amid evolving market dynamics; this followed a rebranding and product suite enhancement announced in mid-2025 to capitalize on heightened demand for flexible fixed income solutions.
