Goldman Sachs Lays Over a Thousand Employees, Wall Street Worries Over 'September Curse': Previously, Buffett sold Bank of America, and later Goldman Sachs planned to lay off a thousand employees. As September approaches, Wall Street remains somewhat unsettled. At the same time, US stock investors are preparing for a potentially volatile September, the weakest month in US stock history. According to Wind data, the S&P 500 index has fallen an average of 1.2% in September since 1928. Although the Fed's September interest rate cut is almost certain, Wall Street is still concerned about whether the "soft landing" narrative that drove the US stock market up in 2024 can continue.
