Mutual interest

FOR the first time in her life, 32-year-old Wang Ying, an office worker in Shanghai earning 5,000 yuan a month with little prospect of promotion, feels rich, thanks to the booming stock market. 

She knows nothing about the stock market and has never bought a single share. But like millions of other Chinese investors, Wang has put a big part of her savings into a mutual fund. The initial investment of 10,000 yuan she made in July has already appreciated by 45%.
