About FSMDX

Fidelity Mid Cap Index Fund is a mutual fund that aims to closely replicate the performance of the Russell Midcap Index, which tracks the returns and characteristics of mid-capitalization U.S. companies. The fund utilizes a passive, index-tracking strategy, investing at least 80% of its assets in the same securities as its benchmark index, which covers a broad spectrum of industries across the American mid-cap market. This approach provides diversified exposure to approximately 800 of the smallest companies in the Russell 1000 Index, representing sectors such as technology, industrials, financial services, and consumer discretionary. The fund is designed with cost efficiency in mind, boasting a low expense ratio and minimal turnover, making it a notable choice for investors seeking broad mid-cap U.S. equity exposure. With assets exceeding $40 billion and more than 800 holdings, it plays a significant role in the mutual fund market by offering investors a straightforward, low-cost avenue to access mid-sized U.S. companies, which often represent a blend of growth potential and established business operations.
