The U.S. non-farm data for August left both optimistic and pessimistic sides not entirely "satisfied." The unemployment rate fell from 4.3% to 4.2%, which met expectations and extinguished the recession signals released by the "Sam Rule." However, the addition of 142,000 jobs in August was below the expected 165,000, and the previous value was also significantly revised down, adding to the signs of a slowing labor market. The S&P fell 1.7%, down over 4% for the week, the Dow dropped 1%, down nearly 3% for the week, and the Nasdaq fell 2.6%, down 5.8% for the week, entering a technical consolidation phase.
