The S&P 500 closed at 7,585.73 on September 15 2026, down 0.45% on the day and 0.7% from 7,636.36 on September 9, as the 10-year touched 5% into the FOMC. The index remains above the 7,300 the melt-up-completion leg requires and far above any level that would engage the vol-expansion leg, so neither invalidation leg fires on the index component.
