Managed by BlackRock’s municipal bond team, the fund employs rigorous credit research and active duration positioning to navigate changing market conditions, including shifts in yield curves and credit spreads. Portfolio composition is predominantly investment in bonds with minimal equity exposure and a modest cash sleeve for liquidity management.
