Assets Under Management
The fund has $1 billion in total assets, which is above the $337 million average for the Government Mortgage-Backed Bond 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.
FGMNX 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 Fidelity GNMA expense ratio is average compared to funds in the Government Mortgage-Backed Bond category. Fidelity GNMA has an expense ratio of 0.44%, which is 50% 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. Fidelity GNMA has a portfolio turnover rate of 639%, indicating that holds its assets around 0.0 years. By way of comparison, the average portfolio turnover is 367% for the Government Mortgage-Backed Bond category.

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.
