Assets Under Management
The fund has $3 billion in total assets, which is above the $686 million average for the Mid-Cap 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.
FMDGX 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 Mid Cap Growth Index expense ratio is low compared to funds in the Mid-Cap Growth category. Fidelity Mid Cap Growth Index has an expense ratio of 0.05%, which is 95% 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 Mid Cap Growth Index has a portfolio turnover rate of 53%, indicating that holds its assets around 0.0 years. By way of comparison, the average portfolio turnover is 76% for the Mid-Cap Growth category.
