Assets Under Management
The fund has $89 million in total assets, which is below the $2 billion average for the Large Growth category.

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.
RMBHX 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 RMB A expense ratio is high compared to funds in the Large Growth category. RMB A has an expense ratio of 1.23%, which is 28% higher than its category average, making the fund expense ratio grade a D. 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. RMB A has a portfolio turnover rate of 43%, indicating that holds its assets around 0.0 years. By way of comparison, the average portfolio turnover is 54% for the Large Growth category.
Recently, in the month of July 2026, RMB A returned 1.9%, which earned it a grade of A, as the Large Growth category had an average return of -3.1%. 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.
RMB A has a trailing yield of 0.08%, which is above the 0.06% category average. The fund normally distributes its income annually and its capital gains annually.
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.
