The underlying logic of the possible subsequent plunge in the US stock market:

1) The Federal Reserve continues to cut interest rates, and the US economy is entering a recession;

2) China's stock market continues to soar, the economy is recovering strongly, and hot money from Europe and the United States flows into China;

3) The US stock market has reached a historical high, and it is cold at high altitudes. The downward adjustment is also in line with the market's boom and bust cycle.
