Fidelity ZERO Large Cap Index Fund (FNILX) is an open-end mutual fund that seeks to provide investment results corresponding to the total return of stocks of large-capitalization U.S. companies by normally investing at least 80% of its assets in common stocks included in the Fidelity U.S. Large Cap Index, a float-adjusted market capitalization-weighted index reflecting the performance of the largest 500 U.S. companies based on float-adjusted market capitalization. The fund offers a zero expense ratio with no minimum initial investment, low turnover of approximately 3%, and a share class type designated as no load, targeting retail investors seeking passive exposure to the large blend equity segment. It is part of Fidelity's ZERO index fund suite, managed under Fidelity Concord Street Trust, with portfolio managers Louis Bottari and Robert Regan overseeing operations since inception.
The fund provides investment in a diversified portfolio heavily weighted toward U.S. stocks (approximately 99.53%), spanning sectors such as financial services, technology, and consumer goods, with top holdings including companies like Berkshire Hathaway Inc., Microsoft Corp., and NVIDIA Corp.; it maintains minimal non-U.S. stock exposure (0.47%) and no bond or cash allocations. Assets under management stand at over $15 billion, with a TTM yield of 0.93% and daily NAV pricing. Fidelity Concord Street Trust, the series trust for FNILX, is headquartered at 245 Summer Street, Boston, Massachusetts, and operates primarily in the United States.
Launched on September 13, 2018, as part of Fidelity's expansion of its zero-fee index offerings following the introduction of funds like FZROX and FZILX, FNILX has grown significantly, achieving strong performance with year-to-date returns of approximately 16.30% in 2025, 25.47% in 2024, and cumulative returns exceeding 104% since inception. Recent operational stability includes maintenance of its zero expense ratio and low turnover amid market volatility, with no reported mergers, acquisitions, partnerships, or strategic shifts specific to FNILX in 2024 or 2025; the fund continues to serve as a core holding for long-term investors tracking large-cap U.S. equity performance.
