Fraudsters make hay from uncertainty on bourses

As Wu Zhen'an was anxious about the tumbling Chinese stock market in recent weeks, he was initially pleased to receive a call that appeared to help him try to recover his fortunes.

"The caller talked about several stocks and asked whether I wanted to buy them. To my surprise, what he said tallied with my purchases," said Wu, from Nanjing, capital city of Jiangsu province.

Then, the caller analyzed the unstable stock market and introduced his rich trading experience to Wu, asking whether he needed his help.
