  "account": "On Friday, stocks in Hong Kong and mainland China plummeted, mirroring a severe downturn in US technology companies, losing over US$2 trillion in market value due to fears that a Democrat-controlled Congress could disrupt AI infrastructure development. The Hang Seng Index fell 1.5 percent to 24,458.68 by 9:32am, while the Hang Seng Tech Index experienced a staggering 2.1 percent decline.
