BlockBeats News, August 18th: According to the August Global Fund Manager Survey by Bank of America, 32% of investors view the artificial intelligence bubble as the biggest tail risk event. A tail risk refers to the likelihood of extreme and rare events that could have a significant impact on financial markets. The survey also revealed that 27% of the surveyed investors see a disorderly rise in bond yields as the second-largest tail risk event.

At the same time, investors' confidence in U.S. stocks outperforming other regional markets has further strengthened. The survey indicated that 27% of the fund managers interviewed have an overweight position in U.S. stocks relative to the global benchmark weight, a 3-percentage-point increase from July, reaching the highest level since December 2024.

Year-to-date, U.S. stocks have continued to outperform most overseas markets, with the S&P 500 Index posting a 13% cumulative gain and the Euro Stoxx 600 Index rising by 10%. However, the stock markets in Japan and South Korea have still outperformed U.S. stocks during the same period.
