Thornburg Short Duration Municipal Strategy

Strategy Overview
The Short Duration Municipal Strategy is an actively managed diversified portfolio of municipal bonds with an average maturity of less than five years and average duration range of less than three years. All bonds are investment grade at time of purchase. The strategy applies a relative value framework, focusing on fundamentals and valuations to identify inefficiencies in the market. Team members are responsible for credit research, portfolio construction, trading and risk oversight and have the flexibility to source ideas across sector, geography and issuer. The strategy maintains exposure across the maturity spectrum in order to manage duration, hedge against interest rate fluctuations and limit taxable events.

Overview

Why Invest in This Strategy?

  • Actively managed diversified portfolio of high-quality municipal bonds with an average duration of no more than three years.

  • Income-seeking strategy that aims for a stable net asset value, making it attractive for those with a short investment horizon, and is positioned to quickly take advantage of any increases in short-term interest rates.
