Fund Details
MoA Equity Index Fund Overview
MoA Equity Index Fund (MAEIX) is a passively managed U.S. Equity Large Blend fund. Mutual of America launched the fund in 1993.
The investment seeks investment results (before fees and expenses) that correspond to the investment performance of the S&P 500® Index. The fund primarily invests in the 500 common stocks included in the S&P 500® Index to replicate, to the extent practicable and cost effective, the weightings of such stocks in the index. Under normal circumstances, at least 80% of the fund's total assets are invested in securities included in the S&P 500® Index.

Assets Under Management
The fund has $5 billion in total assets, which is below the $6 billion average for the Large Blend category. Normally, lower assets under management translates to higher average expense ratios, and greater total assets are desired. However, for some investment categories, such as small-cap investing, it may be difficult for the manager to fully employ the desired active strategy if assets grow too large or too quickly.
MAEIX Performance and Fees
The expense ratio measures how much of a fund’s assets are used for administrative expenses and operating expenses, including adviser fees and fees for the transfer agent and custodial services. The MoA Equity Index Fund expense ratio is low compared to funds in the Large Blend category. MoA Equity Index Fund has an expense ratio of 0.14%, which is 83% lower than its category average, making the fund expense ratio grade a A. While it is difficult to predict returns, it is known that high annual expense ratios reduce your rate of return, and excessive fees are difficult to overcome. Active management normally comes with higher expense ratios than passive index management. Certain investment categories such as small company and foreign also normally have higher expense ratios. It is best to compare fund expense ratios against the category averages for meaningful assessments.
High portfolio turnover can translate to higher expenses and lower aftertax returns. MoA Equity Index Fund has a portfolio turnover rate of 2%, indicating that holds its assets around 0.4 years. By way of comparison, the average portfolio turnover is 48% for the Large Blend category.
Recently, in the month of July 2026, MoA Equity Index Fund returned -0.1%, which earned it a grade of D, as the Large Blend category had an average return of 0.4%. The letter grades of A, B, C, D and F are based upon relative rankings within the investment category. A grade of A, for example, would indicate that the return is in the highest 20% for that time period compared to all funds in that category.
MoA Equity Index Fund has a trailing yield of 0.98%, which is above the 0.56% category average. The fund normally distributes its income monthly.
It’s natural to seek the best-performing investments, but you must consider the relationship between risk and return and the impact of costs and taxes on your realized returns.
