S&P 500 Earnings Growth of 31% in Q2, AI Drives Shift to Profit Center

On August 16, the S&P 500 Index reported a 31% year-on-year increase in earnings for the second quarter, marking the highest growth rate since 1992 and significantly exceeding the expected 23%. The development of AI has notably improved net profit margins, rising from a long-term average of 14% to nearly 16%. Mark Hackett, Chief Market Strategist at Nationwide Funds Group, pointed out that AI has transformed from a cost center to a profit center this year. The earnings growth has outpaced the index's rise, leading to a decline in the S&P 500's price-to-earnings ratio from about 26 times at the beginning of the year to below 22 times, completing a valuation reset. Scott Rubner, Head of Strategy at Citadel Securities, stated that earnings are currently driving the market, rather than valuation expansion. Approximately three-quarters of U.S. companies that have reported earnings exceeded expectations for both earnings per share and revenue, with the surprise rate for small and mid-cap stocks nearing historical highs since the pandemic. European companies achieved a record net profit margin of 12% in the second quarter, and the MSCI Europe Index saw an 18% year-on-year earnings growth, the best since 2022. In the Asia-Pacific region, earnings expectations have been revised upward by nearly 10% since June, the largest increase for the same period since 2009. Strategists have raised their full-year earnings growth forecast for the S&P 500 from 15% at the beginning of the year to 27%, with the year-end target price average rising to 7,894 points. Nvidia's earnings report will become the last important piece of the puzzle this month, further testing the strength of this earnings bull market.
