Data spanning 1950 through 2026 identifies October 28 as the historically best-performing trading day for the S&P 500, with an average gain of 0.50%. This calendar trend coincides with a scheduled Federal Reserve meeting.
Why it matters
Understanding seasonal market patterns can help investors maintain perspective on day-to-day volatility during key economic events. Historical averages provide context for market moves rather than signaling guaranteed outcomes for individual portfolios.
Since 1950, October 28 has yielded a 0.50% average gain for the S&P 500, while October 19 marks the year's worst day with an average 0.52% decline. The SPDR S&P 500 ETF Trust remains up 12.7% year-to-date in 2026.
