According to Odaily, Bank of America strategist Michael Hartnett has raised concerns about a potential bubble in U.S. stocks and cryptocurrencies due to their strong rebound. Data compiled by the institution indicates that the price-to-book ratio of the S&P 500 index surged to 5.3 times in 2024, nearing the peak of 5.5 times seen during the tech bubble in March 2000. Hartnett warns that if the S&P 500 approaches 6666 points, which is approximately 10% higher than its current level, there is a significant risk of "overshooting" by early 2025. Despite these concerns, the bank's bull and bear market indicator has yet to show signs of exuberance among global investors.
