On March 17, according to 4E monitoring, under the continuous impact of Trump's tariff policy, the three major US stock indexes collectively closed down after experiencing significant fluctuations last week. The Dow fell by about 3.1%, marking its worst weekly performance since March 2023. The S & P 500 fell by 2.27% and the Nasdaq fell by 2.43%, both falling for the fourth consecutive week. Large technology stocks rebounded by nearly 8% except for NVIDIA, and all other weekly losses were closed. The crypto market fluctuated violently, and bitcoin rebounded after being inserted to a recent new low on Tuesday, basically fluctuating around the 83,000 dollar. U.S. stocks closed up across the board on Friday, driving bitcoin to break through the 85,000 dollar, but the weekend failed to extend the rally due to lack of liquidity. At the time of writing, it was 83,144 dollars, up nearly 1.5% in the past 7 days. Most other mainstream tokens rose slightly. Ethereum is trying to stand above $1,900. BNB was boosted by Abu Dhabi's 2 billion dollar investment and the recovery of meme on the chain. It rose nearly 10% in the past 7 days.
