BlackRock has expressed optimism about the performance of U.S. stocks in 2025, citing 'exceptionalism' as a driving factor for growth. The firm believes that artificial intelligence-driven stocks will play a key role in this upward trend. However, concerns about U.S. debt levels pose a potential risk to the economic outlook for the same period. Meanwhile, HSBC predicts a 10% rise in the S&P 500 index by the end of 2025, projecting it to reach 6,700 points.
