No investor would have expected a retailer of agricultural machinery to be the dark horse on ChiNext, the NASDAQ-style trading board that has remained subdued after a roller-coaster ride post-debut.

The share price of Sichuan Jifeng Agricultural Machinery Chain Co Ltd yesterday jumped by the 10-percent daily trading limit to 88.11 yuan after rising consecutively over the past 13 trading days.

The Chengdu-based agricultural machinery firm has exceeded investor expectation since its debut on Oct 30, running ahead of hi-tech enterprises and the star-studded film producer Huayi Brothers, as the best-performing stock on ChiNext.
