SOME are in it purely for the money. Others just want a few extra yuan to buy a meal. And then there are also those who trade for fun or to spend time among friends.

    Millions of mom-and-pop investors — from pensioners, to security guards, to students — dominate China’s stock market, conducting about 80 percent of all transactions. But this year they have experienced one of the most tumultuous periods in the country’s financial history.

    China’s stock market first soared — more than doubling in the six months to May — only to crash. Since June, prices have fallen about 40 percent on concerns that growth in the world’s second-biggest economy is slowing down faster than previously thought.

    “Trading stocks is my biggest hobby,” said 90-year-old Wang Cunchun, who only started to invest in equities after he retired from a stationary store in Shanghai.

    He joins other retirees in one of the many brokerages dotted around China where people gather not just to trade stocks but to enjoy the company of fellow investors and, on hot days, take advantage of the air conditioning.

    “There are many old neighbors coming to the brokerage house,” he said. “I don’t know how to use computers so my neighbors actually help me sell and buy.”

    Trading stocks is hobby for 16-year-old high school student Qian Yujie. But in contrast to Wang, he places his orders from a desktop computer at his home.

    He began trading at the age of 13 when his father gave him 2,000 yuan (US$320) to learn about stock investing. He fits trading into his schedule when he has a day off school.

    “I like maths and want to study finance in college and I think it’s very helpful for job hunting,” Qian said.

    While some retail investors say they want to make their fortune on China’s stock market, electrician Gao Haibao, 55, has a more modest approach by aiming to make about 10 yuan everyday, or US$1.50.

    “I make money to buy a meal everyday,” he said. “I’m happy with it. I’m making money.”

    And Du Mingpeng, 50, a security guard at a jewelry store, hopes to profit from his investments to give money to his son who is getting married. (SD-Agencies)
