S&P 500 Off 1.75% in a Typically Weak September

S&P 500 fell 1.75% in September through Sept. 20, Nasdaq down 1.5%, Yahoo Finance reported. September has averaged a 1.1% loss since 1928, the worst month on record. For savers, context helps: the index was still up 12.3% in 2026. I see this seasonal dip as noise, not a verdict on the year.
