Analysts note that the ongoing AI trading frenzy continues to fuel the U.S. stock market, with in-line U.S. retail sales data further bolstering market confidence. In a recent report, Morgan Stanley projected that the S&P 500 index could reach 8,300 points within the next 12 months. The team led by Mike Wilson also raised its year-end target for the S&P 500 from 7,800 to 8,000 points.
