3 Harbor Mutual Funds for a Research-Driven Portfolio

The investment platform at Harbor was established more than 35 years ago through the selection of external boutique managers instead of internal portfolio management. The organization bases its mutual fund design and portfolio diversification on its external boutique manager selection model. 

The company starts its process by locating boutique investment managers who focus on particular worldwide markets through established investment methods. The team performs complete manager due diligence through method verification and achievement assessment instead of relying on manager self-reported data. The selection process for managing Harbor mutual funds requires teams to fulfill specific criteria. It tracks its investment strategies continuously to verify that the actual results match their originally set targets. Managers are replaced if the investment strategies do not perform, or if market conditions require different expertise. This combination of factors at Harbor establishes it as a dependable investment option.
