    Question

    Nike Removed From S&P 100 Index Effective September 21 Rebalancing

    Direct answer

    S&P Dow Jones Indices announced the deletion of Nike from the S&P 100 effective September 21 as part of its regular quarterly rebalancing schedule. The exclusion reflects persistent top-line declines and margin pressure that have pushed the equity to 12-year valuation lows, while also rendering it the lowest-weighted constituent in the price-weighted Dow Jones Industrial Average.
