    Question

    Nike Removed From S&P 100 Index in Rebalance Effective September 21

    Direct answer

    S&P Dow Jones Indices confirmed Nike's removal from the S&P 100 index effective September 21. The decision follows persistent fundamental weakness, multi-year operating margin compression, and stock performance hovering near 12-year lows. Index removal triggers forced divestment by passive mega-cap funds and benchmark-tracking ETFs, intensifying technical downside pressure while raising market focus on Nike's remaining standing in the Dow Jones Industrial Average.
