Core Viewpoint - The article highlights a significant downturn in the U.S. stock market, particularly in technology stocks, driven by disappointing employment data and escalating trade tensions under the Trump administration, leading to increased market volatility and a shift towards risk-averse investments [1][10][12]. Group 1: Market Performance - On the first trading day of August, all three major U.S. stock indices fell sharply, with the Nasdaq dropping over 2%, primarily due to a sell-off in technology stocks [1][3]. - The Dow Jones Industrial Average decreased by 1.23%, the S&P 500 fell by 1.6%, marking the largest single-day decline since May, while the Nasdaq Composite plunged by 2.24% [3]. - The technology sector, particularly the "Big Seven" tech companies, saw a collective drop of 2.99% [3]. Group 2: Employment Data - The U.S. non-farm payrolls for July increased by only 73,000, significantly below the expected 100,000, with prior months' data revised down by 258,000, resulting in an average increase of just 35,000 over the past three months, the worst performance since the pandemic began [11]. - The unemployment rate rose to 4.2%, while wage growth was slightly above expectations at 3.9%, indicating a weakening labor market [11]. - Following the employment report, the probability of a Federal Reserve rate cut in September surged to nearly 90%, with significant declines in U.S. Treasury yields and a drop in the dollar index [11]. Group 3: Trade Tensions - European markets experienced a sharp decline, with the French CAC40 index falling nearly 3%, marking its worst performance in four months, driven by concerns over new tariffs imposed by the U.S. on Swiss goods [12][13]. - The tariffs have particularly impacted pharmaceutical stocks, with companies like Novo Nordisk experiencing a drop of 6% [13]. - Analysts suggest that the increased tariffs could negatively affect future earnings for European companies that rely heavily on the U.S. market, with potential profit impacts estimated between 2% to 10% [13]. Group 4: Investment Strategy - In light of the current market conditions, investment firms recommend increasing allocations to safe-haven assets such as gold and U.S. Treasuries while maintaining some equity positions to capture potential market rebounds [13]. - The "雪球三分法" (Snowball Three-Part Method) is suggested for asset allocation, emphasizing diversification to mitigate risks while seizing structural opportunities [14].
