Barclays stated that 85% of S&P 500 companies surpassed Q2 earnings estimates, significantly above the long-term average of 76%. Revenue increased by 11.2% year-over-year, and EPS surged by 25.1%, primarily driven by Big Tech. However, Barclays observed a rare pattern where both earnings beats and misses led to negative stock reactions on average, indicating that investors had largely factored in the positive news beforehand.
