American Century Securitized Credit ETF (ASEC) is an actively managed exchange-traded fund offered by American Century Investments that seeks to deliver high income and diversification benefits to traditional core fixed income allocations by investing primarily in investment-grade U.S. securitized debt securities within non-traditional asset-backed sectors, including aircraft and equipment leases, consumer loans, cell towers, and digital infrastructure; with opportunistic exposure to residential mortgage-backed securities (RMBS), commercial mortgage-backed securities (CMBS), collateralized loan obligations (CLOs), and select government and nongovernment agency securities. The fund operates to complement core bond portfolios by expanding exposure beyond conventional fixed income, aiming to enhance yield while adding diversification and resilience to rate environments; it invests across securitized credit instruments such as asset-backed securities (ABS), RMBS, CMBS, CLOs, and related securitized debt, and may also allocate to related investment-grade assets as opportunities arise. The ETF is structured to provide liquidity and transparency for investors seeking a specialized fixed-income sleeve within a broader portfolio, with a management team applying an active approach to security selection and sector allocation. It carries a gross expense ratio of 0.29% and is managed from American Century Investments’ headquarters, with a distribution and trading presence on the NASDAQ Exchange. The firm positions ASEC within its broader fixed-income ETF lineup, alongside other municipal, corporate, and multi-sector products, and targets institutional and individual investors seeking enhanced income generation and diversification within a securitized credit framework. Founding context and headquarters: American Century Investments is headquartered in Kansas City, Missouri, and operates as a global asset manager offering a range of investment products and strategies across equity, fixed income, and multi-asset platforms. The firm’s latest changes include the launch of ASEC in 2026, expanding its ETF platform and fixed-income offerings to address demand for securitized credit exposure and diversified income solutions. Subsidiaries and parent relationships follow American Century Investments’ corporate structure, with ASEC positioned as a product within the American Century ETF Trust framework. Market coverage emphasizes U.S. investors and institutions seeking sophisticated securitized credit exposure within a diversified fixed-income plan. The vehicle adheres to a strategy emphasizing investment-grade securitized debt in non-traditional ABS sectors, with flexible allocation to RMBS, CMBS, CLOs, and related securities to meet income, diversification, and risk management objectives.
