Wall Street investment banks warned that it may be difficult to recapture the profits of the popular transactions that boosted profits in the second quarter. This indicates that the boom in banking market business may begin to cool down. A major US bank executive said at an industry conference this week that transaction revenue growth has slowed after the previous quarter's unprecedented results. During the second quarter, the AI-related stock trading boom drove bank profits to break records sharply. Bank of America CEO Brian Moynihan said on Monday that the bank's sales and trading revenue for the third quarter will be the same. The statement caused its stock price to drop 5% on the same day, and dragged down peers' stock prices. Morgan Stanley Co-President Daniel Simkowitz said, “The market situation in the second quarter of this year was quite special. It's safe to say that the third quarter will not replicate the success of the second quarter.” J.P. Morgan Chase Co-President Doug Pettnor said that after a record season, the bank's market revenue is expected to decline seasonally from month to month.
