A woman surnamed Wang sold all her stocks days ago and is now waiting for a correction in China's runaway stock market.
"The market has reached its peak and is certain to fall," said the new investor in her thirties.She had beginner's luck,making a 10,000-yuan profit out of 30,000 yuan in two months."I will start buying stocks again after a major fall."
Another investor,Old Jiang,60,opened a share-trading account in April and he put 20,000 yuan,a small part of his savings,into the market.
It's just for fun and it helps me kill the time," said the retiree who said he did not care much about the gains.
What Wang and Yang are doing presents a different picture from that painted by some domestic media.Reports often recounted recounted（叙述）irrational Chinese investors eagerly jumping into the stock market,expecting quick money and unaware of the risks.
There are also frequent stories about a senior betting all of his or her hard-earned savings on the stocks,or about a man putting all his possessions up as collateral （抵押物）to get a loan for stocks.
But in fact,Wang is among millions of investors who are not so optimistic about the future development in the market.
Statistics from the Shenzhen Stock Exchange showed,by the end of March,more than 3.4 million investors in the bourse have sold all the stocks in their portfolios,or made no transactions after opening new accounts,according to earlier reports.
In related development,Former US Federal Reserve Chairman Alan Greenspan warned Wednesday China’s market was unsustainable and he expected a dramatic contraction（紧缩） at some point.
Greenspan’s remark followed warnings from Li Ka-shing,Asia’s richest man.China’s stock valuations “must be a bubble(泡米)”and prices are likely to fall,said Li last week
