About MCBLX

The MassMutual Core Bond Fund Administrative Class is a mutual fund focused on providing investors with a high total rate of return while maintaining prudent investment risk and capital preservation. As an intermediate core bond fund, it primarily invests in a diversified mix of investment-grade U.S. fixed-income securities, including government, corporate, and securitized debt. The majority of assets are in domestic bonds, but the fund also allocates a portion to foreign bonds, enhancing portfolio diversification. Its portfolio management strategy is designed to limit exposure to below-investment-grade securities, with less than 5% typically held in such assets. The fund maintains a moderate interest rate sensitivity, with an effective duration of just over six years, making it sensitive but not overly reactive to changes in interest rates. Dividends are distributed regularly, providing a steady income stream to shareholders. The fund holds hundreds of different securities, ensuring broad diversification within the fixed-income market and aiming to mirror or outperform major bond benchmarks. Managed by MML Investment Advisers, LLC, and backed by MassMutual’s institutional resources, this fund is commonly used as a core fixed-income holding for institutional investors, retirement plans, and individual investors seeking stable, long-term fixed income exposure.
