Hong Kong’s equity market hit a one-year high and led a surge in global stocks early Thursday, as the China-stimulus rally received further propulsion from a report Beijing was considering a $142 billion capital injection into the country’s big banks. The Hang Seng Index HSI 4.16% in Hong Kong jumped 4.2%, taking its gains to 9.2% over just the last three days after the Peoples’ Bank of China on Tuesday revealed a swathe of stimulus measures designed to aid the beleaguered housing sector, support the stock market and help the economy hit Beijing’s economic growth target of 5%.
