SHANGHAI (BLOOMBERG) - China's government has spent as much as 900 billion yuan (S$200.6 billion) in the past two months to prop up the nation's stock prices, almost half the funds allocated for a market rescue, according to US investment bank Goldman Sachs.

The injection amounts to 2.2 per cent of the country's free- float market capitalization, or shares available for trading, Goldman Sachs strategists led by Chenjie Liu wrote in a report dated Aug. 5, citing the firm's own analysis of stock-market liquidity and fund flows.

Speculation that the government will unwind its intervention is probably overdone, with more than 1 trillion yuan still available to support the market, Goldman said.

Chinese shares have lost about US$3.4 trillion (S$4.7 trillion) of market value since June 12, with the Shanghai Composite Index dropping 30 per cent amid an exodus of leveraged investors and concern that valuations had grown too expensive after a record-long bull market. Policy makers responded by unleashing an unprecedented series of support measures, including direct equity purchases by state agencies and government-owned companies.

"This implies sufficient market-support funds to continue to provide a downside cushion to the equity market as the later stages of retail deleveraging unfold," Liu wrote.

The Shanghai Composite will probably trade in a range in the "near term," supported around the mid-3,000 level by government buying and capped at about 4,500 by the prospect of selling by brokerages and others investors who have been "constrained" from offloading shares, Goldman said. The Shanghai index dropped 0.1 per cent to 3,692.27 at 11:14 a.m. local time on Thursday.

State buying has probably focused on "blue-chip" and defensive companies including banks, insurers, food and health-care companies, the analysts wrote. The government has yet to disclose a complete picture of its share-purchase program.
