- Optimum Large Cap Growth Fund (OILGX) is an open-end mutual fund that seeks long-term growth of capital by investing at least 80% of its net assets in equity securities of large market capitalization companies, defined as those with market capitalizations similar to companies in the Russell 1000 Growth Index; it may also allocate up to 20% to foreign securities including American Depositary Receipts, derivatives such as futures and options, and fixed income securities including those rated below investment grade. The fund offers institutional class shares with a net expense ratio of 0.95%, no front-end or deferred loads, and a minimum initial investment of $1,000; as of late 2025, it manages approximately $2.04 billion in total net assets, with top holdings concentrated in leading growth names such as NVIDIA Corporation, Microsoft Corporation, Apple Inc., Amazon.com, Inc., and Meta Platforms, Inc., representing over 54% of the portfolio. It belongs to the large growth category, targets investors seeking capital appreciation through U.S.-centric large-cap equities with growth potential, and is available for sale in the United States.
Launched on August 1, 2003, and domiciled in the United States, the fund is part of Optimum Fund Trust and managed by a team at Delaware Management Company (DMC), a series of Macquarie Investment Management Business Trust, with key portfolio managers including Keith Lee and Jeffrey Bourke (since July 2022), Hal Reynolds, Daniel Allen, and Daniel Arche (since January 2023), and Tong Li (since July 2024). The fund's investment adviser operates from headquarters in Philadelphia, Pennsylvania.
In a major strategic development, Nomura Holdings, Inc. announced on April 21, 2025, its agreement to acquire Macquarie Asset Management's (MAM) U.S. and European public investments business—including DMC, the adviser to Optimum Fund Trust—for approximately $1.8 billion, with the transaction completing on November 30, 2025, and including a strategic partnership for product distribution and co-development of investment strategies. This change enhances Nomura's asset management capabilities, adding roughly $180 billion in AUM focused on equities (50%), fixed income (40%), and multi-asset strategies (10%), while Macquarie shifts focus to private markets; shareholder approval was sought for interim sub-advisory agreements to ensure continuity during the transition. No other significant acquisitions, funding rounds, or product launches were reported for the fund in 2024-2025, though portfolio adjustments included new positions in Nu Holdings Ltd., General Electric Company, HEICO Corporation, Halozyme Therapeutics, Inc., and Carnival Corporation & plc.
