About MACMX

BlackRock California Municipal Opportunities Fund Institutional Shares is a municipal bond mutual fund designed to provide investors with income that is exempt from both federal and California state income taxes. The fund primarily invests at least 80% of its assets in municipal bonds issued by California state and local governments, with at least half of the portfolio allocated to investment-grade securities. Under normal market conditions, the fund offers exposure to both fixed and variable rate obligations and may allocate up to 50% to non-investment grade bonds, enhancing its flexibility to seek attractive yields within the municipal bond market. This fund targets intermediate-term California municipal bonds, typically holding securities with maturities of four to twelve years, and maintains an effective duration near six years. By distributing monthly income, it is generally appealing to California residents and institutions seeking tax-advantaged income. Managed by BlackRock, one of the world's largest asset managers, the fund boasts a diversified portfolio with hundreds of bond holdings that finance essential public projects such as infrastructure, clean energy, and utilities throughout California. With a long performance history since its inception in 1988, this fund plays a significant role in facilitating capital for California's public sector while offering institutional investors a specialized vehicle for managing state-specific, tax-exempt fixed income exposure.
