A multi-manager fund that invests primarily in bonds. Bonds are fixed-income securities representing debt obligations that require the issuer to repay the bondholders the principal amount borrowed and to generally pay interest. The objective is to provide current income and the preservation of capital.

Asset Class:



Broad Market/Sector Rotation

Bonds and other debt obligations are affected by changes in interest rates, inflation risk and the creditworthiness of their issuers. High yield bonds generally have greater price swings and higher default risks than investment grade bonds. Return of principal is not guaranteed. In contrast to owning individual bonds, there are ongoing fees and expenses associated with owning shares of bond funds.

Overseas investments can pose more risks than domestic investments due to fluctuations in foreign stock markets, currency values, interest rates, government regulations and political conditions.
