AI Boom Lifts US Stocks, Strategist Sees S&P Breaking 10,000 in Three Years, How Much Longer Can This Rally Last?
TradingKey – U.S. stocks closed at record highs again on Monday; despite growing concerns that a prolonged conflict in Iran through the summer could trigger severe economic consequences, the rally remained undeterred. Since the start of 2026, AI-related stocks have been the core pillar of the S&P 500’s gains, accounting for over 80% of the upward momentum. Veteran Wall Street investment strategist Ed Yardeni has become one of the most optimistic market forecasters, not only raising his year-end S&P 500 target from 7,700 to 8,250, but also providing a long-term outlook of hitting the 10,000 mark in three years. Better-than-expected
