Reuters reports that,

the market initially expected the US-China summit to produce a larger trade agreement, but the current announced results have disappointed investors.
At the same time, whether the trade truce will be extended after expiration has not yet been decided.
Trump said in an interview that China has agreed to purchase 200 Boeing aircraft.
However, this number was below analyst expectations, causing Boeing's stock price to fall more than 4%, and Chinese airline stocks also dropped over 2%.
However, chip stocks defied the trend and strengthened.
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.
