iShares U.S. Equity Factor ETF (LRGF) is an exchange-traded fund that seeks to track the investment results of the STOXX U.S. Equity Factor Index, composed of U.S. large- and mid-capitalization equities selected and weighted through an optimization process to maximize exposure to five target style factors: quality, value, momentum, low volatility, and size; the fund employs a representative sampling technique and invests at least 80% of its assets in component securities of the index or substantially identical investments. Launched on April 28, 2015, by BlackRock, Inc. through its iShares Trust, domiciled at 100 Bellevue Parkway, Wilmington, Delaware, with BlackRock Fund Advisors serving as investment adviser, the ETF maintains a low expense ratio of 0.08% and targets institutional and retail investors seeking factor-based equity strategies in the U.S. market. As of late 2025, LRGF manages approximately $3.0 billion in assets under management, with a portfolio of around 289-291 holdings diversified across sectors such as information technology, financials, and consumer discretionary, featuring top positions in companies like Nvidia Corp. and Microsoft Corp. In a major strategic shift, BlackRock in June 2022 transitioned LRGF from its prior benchmark to the STOXX U.S. Equity Factor Index as part of an enhanced multifactor collaboration with STOXX Ltd., revitalizing the product suite and improving factor optimization while controlling for systematic risks; this change, which also applied to the related iShares International Equity Factor ETF (INTF), has supported consistent performance outperformance relative to peers. The partnership with STOXX expanded further in January 2025 to additional iShares ETFs tracking screened variants of equity factor indices incorporating sustainability screens for controversial activities and carbon emissions, though LRGF itself does not pursue an ESG strategy. LRGF trades on the NYSE Arca exchange, distributes dividends quarterly, and continues to exhibit strong inflows and market-beating returns amid ongoing AUM growth into 2025.
