Mark Spitznagel, founder of Universa Investments, predicts that the U.S. stock market will continue its upward trajectory in the short term, driven by a favorable economic climate characterized by easing inflation and interest rates. According to NS3.AI, Spitznagel cautions that this growth represents the final phase of what he describes as the largest bubble in history, which is poised to burst eventually. He suggests that the S&P 500 could climb to 8,000 points before experiencing a significant downturn, particularly if the Federal Reserve keeps interest rates unchanged for an extended period.
