Nike dropped from S&P 100 after 18 years, remains in S&P 500

Nike will be removed from the S&P 100 index on September 21, 2026, marking its first exclusion in 18 years, though it stays in the S&P 500. The move reflects a decline in Nike's market capitalization relative to other large U.S. companies, signaling sustained underperformance. This index change is a lagging indicator of Nike's weakened market position and may prompt passive fund selling, adding pressure on the stock.
