The S&P 500 closed at 7,807.24 on October 12, 2026, within 0.5% of its record high of 7,818.93 set earlier in the month and up roughly 14% year-to-date. Robust third-quarter earnings growth, consensus forecasts around 29-30% year-over-year, remains the dominant driver, fueled by AI spending and broadening profit gains across technology and other sectors. September CPI and PPI releases due mid-month, alongside the FOMC decision late in October, represent key near-term catalysts that could influence rate expectations and Treasury yields, which have recently approached multi-decade highs. Geopolitical tensions and elevated oil prices add volatility risks while earnings season unfolds.
