(Yicai Global) Sept. 5 -- Positive policy signals caused China's three benchmark indexes to sustain their high streak for the fourth day this week and swelled the trading volume of the Shanghai and Shenzhen exchanges 30 percent over yesterday.

The Shanghai composite index closed 0.96 percent up at 2,985.86 on a CNY340.2 billion (USD47.71 billion) trading volume. The Shenzhen Component Index climbed 0.86 percent to close at 9,783.50 on turnover of CNY457.3 billion. The ChiNext index went up 1.18 percent to 1,689.05, with CNY152.8 billion changing hands.

Non-banking financials, including trust investment, securities and internet financial firms, led the gainers with a 5 percent increase. Augmented reality firms also maintained their strong showing this week, climbing by 3 percent.

The State Council yesterday urged targeted measures, including cutting the reserve ratio requirement -- the amount of liquid assets commercial banks must set aside -- to hold the country's major economic indicators within appropriate ranges.
