According to 4E monitoring, due to weak economic data and Trump's tariff policies, US stocks fluctuated and fell last week, with the three major indexes collectively closing down, with the Dow Jones Industrial Average falling by 2.37%; the S&P 500 fell by about 3.1%, the worst single-week performance since September last year. The Nasdaq fell 3.41% in total, falling for three consecutive weeks, falling by more than 10% from its recent high. Large technology stocks performed sluggishly, Nvidia's market value shrank by $1 trillion from its historical high, and Tesla's historical peak pullback exceeded 46%. The decline in the crypto market has intensified, and the strategic reserves of Bitcoin signed by Trump are lower than expected. In addition, the content of the White House crypto summit is mostly polite remarks, which has not brought surprises to the market, which has intensified the decline in the market. Bitcoin has lost several key support levels in succession, falling to the $80,000 mark, with a decline of nearly 12% in the past seven days, and was reported at $82,150. Other mainstream currencies such as Ethereum have fallen even harder, and market sentiment has fallen to a low point. Trump's tariff policy is capricious, and the non-farm data released last week also failed to provide a clear economic outlook. The market is becoming increasingly tired of uncertainty and risky assets are under constant pressure. Investors are paying attention to the US CPI and PPI inflation data this week, which will directly affect the Federal Reserve's interest rate resolution from March 18 to 19.
