On March 10, according to 4E monitoring, U.S. stocks fluctuated lower last week due to weak economic data and Trump's tariff policy. The three major indices collectively closed down, with the Dow falling by 2.37%; the S & P 500 falling by about 3.1%, the worst weekly performance since September last year. The Nasdaq index fell 3.41%, falling for three consecutive weeks, falling more than 10% from its recent high and falling into a correction range. Large-scale technology stocks performed in a sluggish manner, with Nvidia's market value shrinking by US$1 trillion from its historical high, and Tesla's correction of more than 46% from its historical peak. The decline in the crypto market intensified. The Bitcoin strategic reserve signed by Trump fell short of expectations. In addition, the content of the White House Crypto Summit was mostly polite remarks, which did not surprise the market and exacerbated the market's decline. Bitcoin has lost several key support levels in succession, with the lowest reaching the US$80,000 mark. The decline has widened by nearly 12% in the past seven days, reporting US$82150 at the deadline. Other mainstream currencies such as Ethereum fell even more sharply, and market sentiment fell to a trough. Trump's tariff policy is volatile, and non-agricultural data released last week failed to provide a clear economic outlook. Markets are increasingly tired of uncertainty and risky assets continue to be under pressure. This week, investors are focusing on the U.S. CPI and PPI inflation data, which will directly affect the Federal Reserve's interest rate decision on March 18 - 19.
