Shanghai A shares blazed ahead last week, reaching their highest level in two years. Statements by Securities Commission chairman Zhou Zhengqing urging the market to play a bigger role in the economy helped fuel the rally. A little help from the government also encouraged South Korean stocks to rise 3.67 per cent. A government pledge to push down interest rates helped to break a losing streak that has made Seoul one of the world's worst performers this year. Hong Kong stocks were also high on the winners list last week, as a record-setting rally pushed the index to the 12,250 level. In an indication that overseas investors are bullish on Hong Kong, the Hang Seng London Reference Index jumped 2.6 per cent last week.
