Mutual of America

A contributing factor to the firm's favorable rating is its impressive track record of endurance. The Mutual of America 10-year success ratio is 73%, meaning that over the period, 73% of its products have survived and beaten their respective category median. A high success ratio indicates good performance and provides insight into a firm’s discipline around investment strategy and product development. The firm tends to offer open-end and exchange-traded products at lower costs, a strength of the firm. On average, expenses for the firm's funds land in the second-cheapest quintile of category peers. Mutual of America has undergone a bout of turnover in the past five years, as seen in its lower-than-average portfolio manager retention. This is a concern, as long-term stability tends to support positive results.
