Morningstar Completes Quarterly Reconstitution for Morningstar Market Indexes<\/b><\/p>\n

SpaceX joins index, micro-cap and value gain ground, and concentration remains elevated, headlining a quarter showcasing the ability of the Morningstar Market Indexes to evolve with changing markets, maintaining the most comprehensive, efficient, accurate representation of the entire investable U.S. equity market<\/i><\/p>\n

CHICAGO–(BUSINESS WIRE<\/a>)–
\nMorningstar, Inc. (Nasdaq: MORN), a leading provider of independent investment insights, announced the completion of the third quarter reconstitution<\/a> for the Morningstar Market Indexes.<\/p>\n

\nConducted quarterly to reflect changes across the U.S. equity market, the reconstitution helps ensure the indexes continue to serve as robust, representative, and investable benchmarks for investors. Built on CRSP\u2019s long-established methodology, research foundation, and academic heritage, and now under the Morningstar banner, the Morningstar Market Indexes currently underpin more than $3 trillion in investor assets.<\/p>\n

\nThis includes more than $2 trillion linked to the Morningstar US Total Market Index<\/a>, the parent for the Morningstar Market Indexes, making the update an important event for investors, asset managers, and market participants following the index. Additionally, Morningstar\u2019s research, analytics, and investment platforms will begin using the Morningstar Market Indexes as category benchmarks in the fourth quarter.<\/p>\n

\n“Our quarterly reconstitution is more than an index maintenance event. It provides a transparent and objective view into how the U.S. equity market is evolving and ensures benchmarks continue to reliably reflect the opportunity set for stock investors,\u201d said Amelia Furr, president of Morningstar Indexes<\/b>. “What sets our indexes apart is a methodology designed to capture the most comprehensive U.S. equity opportunity set while minimizing unnecessary turnover. By systematically incorporating major market events \u2015 from IPOs to shifts in company size and style \u2015 we help investors maintain the broadest market exposure without introducing excessive trading caused by short-term market movements.”<\/p>\n

\nAt the core of the reconstitution is the Morningstar US Total Market Index<\/b>, Morningstar\u2019s flagship U.S. equity benchmark, designed to capture the entire U.S. stock market. The index serves as the foundation for many of the industry\u2019s most widely used index-linked investment products, including the world\u2019s largest mutual fund, and is a critical barometer of changes shaping the U.S. equity landscape.<\/p>\n

“<\/i>While SpaceX dominated the headlines three months ago, its IPO has had only a modest impact on the US Total Market Index so far, largely due to its limited free float,\u201d said Alex Poukchanski, director of analytics at Morningstar Indexes<\/b>. \u201cBecause our flagship index represents the entire U.S. equity market, we can capture emerging market trends. For example, beneath the surface, market leadership has broadened. While the top end of the U.S. stock market remains relatively concentrated, micro caps and value stocks have outperformed larger growth companies, underscoring the importance of diversification and exposure across size and style segments.”<\/p>\n
