Data Analytics and Indices

Equity investors enjoyed another month of meaningful gains in September 2025 — the fifth consecutive monthly advance — with the S&P 500® Index (SPX) rising 3.5% to 6,688 and the Russell 2000® Index (RUT) up nearly 3% to 2,436. Both benchmarks ended the month near all-time highs, supported by the long-anticipated Federal Reserve interest rate cut and a relatively stable geopolitical backdrop.
