The non farm payroll data released by the United States last Friday caused a huge uproar on Wall Street, as Goldman Sachs quickly raised its economic recession forecast and global hedge fund bearish sentiment intensified. Due to unexpectedly lower than expected employment data, Wall Street's forecast for the US economy has become more pessimistic, and US stocks also fell sharply last Friday. Goldman Sachs released a report over the weekend stating that they have raised their risk expectations for a US economic recession. Meanwhile, Goldman Sachs' survey also shows that global hedge funds are accelerating the increase of short positions, indicating their pessimistic expectations for the US economic outlook.
