US-China summit ends with symbolic wins for Trump but no major deals — bad for Nvidia, Boeing, and US farmers depending on Chinese demand.

• Trump left Beijing with no chip deal for Nvidia, which is bad news given the stock's high valuation and reliance on Chinese growth.
• China hinted at buying 200 Boeing planes, but Boeing stock fell 4% because the market doubts it will happen while China builds its own COMAC.
• Washington wants China to ramp up farm purchases as US ground beef prices top $6.90 per pound, but Beijing has cheaper suppliers in Brazil and Russia.
• Visa and Mastercard pushed for China access, but Beijing will not let US payment systems dominate after watching sanctions cut off Russia.
• The Chinese currency is strengthening against the dollar and global central banks are using more RMB, weakening US financial leverage.

Outlook: China will likely keep giving Trump symbolic gestures while building its own alternatives and slowly reducing dependence on the US.
