SF share rally result of idle speculation, economists believe

The skyrocketing share value of SF Holding, China's largest courier company, has come back down to earth, but analysts are concerned that its low share trading value will continue to attract idle money for speculative activity.

The company has been increasing by the 10 percent limit for four consecutive trading days, but on Wednesday afternoon it slipped by 2 percent at one time and closed at 70 yuan ($10.18), for an increase of 4.79 percent.

The strong surge was stimulated by its backdoor listing on the Shenzhen Exchange market last week. The total value of the delivery service provider reached 292.9 billion yuan at close of play on Wednesday.
