S&P 500 earnings activity accelerated, with 86% of reporting firms beating EPS estimates and 79% posting year-over-year profit growth. Key highlights include Palantir's 29.5% surge on strong commercial demand, Disney's gain on EPS beat and buyback boost, and Airbnb's double beat. Conversely, CVS, AMD, Uber, and Kraft Heinz saw share declines despite earnings beats due to guidance concerns or broader market weakness.
