JPMorgan Fundamental Data Science Mid Core ETF (MCDS) is an actively managed exchange-traded fund that seeks long-term capital appreciation by investing primarily in equity securities of mid-cap companies. The fund employs a proprietary fundamental data science-enabled investment approach, combining research, data insights, and risk management to forecast the financial prospects of securities, identify those priced favorably relative to their risk levels, and construct a diversified portfolio across sectors such as industrials, financials, consumer discretionary, information technology, and health care; it benchmarks performance against the Russell Midcap Index while maintaining a weighted average market capitalization of approximately $31.43 billion and holding around 181 securities. Launched on August 7, 2024, as part of J.P. Morgan Asset Management's Fundamental Data Science ETF Suite on the Nasdaq Stock Exchange—which also includes the Large Core ETF (LCDS) and Small Core ETF (SCDS)—MCDS represents a strategic expansion into data-driven active ETFs targeting core equity segments for institutional and retail investors.
