The U.S. Core Fixed Income strategy invests across the major investment-grade bond sectors in an effort to create a broadly diversified, high-quality, intermediate-duration, fixed income portfolio, while controlling risk relative to the benchmark.

We believe that significant areas of the bond market are inherently inefficient and mean reverting. Opportunities exist to exploit the bond market's inefficiencies and mean reversion tendencies through a diverse collection of active positions in duration, yield curve, sector allocation, sector management and security selection encompassed within a risk-managed framework.

Underlying Tenets:

  • Proprietary Fundamental Research
  • Diversified Sources of Return
  • Active Risk Budgeting
