Reuters reports that

the market initially expected the China-U.S. summit to produce a larger trade agreement, but the announced results have disappointed investors.
At the same time, whether the trade truce will be extended after it expires is still undecided.
Trump said in an interview that China has agreed to purchase 200 Boeing aircraft.
However, this number is below analyst expectations, causing Boeing's stock price to fall more than 4%, and Chinese airline stocks also dropped over 2%.
However, chip stocks are defying the trend and rising.
SMIC stated that overseas clients are bringing orders back to China, driving up Chinese chip stocks, and chip equipment manufacturer AMEC also surged 17% due to strong order expectations.
