The one that stunned me a lot is the recent China Gaoxian's suspension. There are simply too many unknown mines among these S-Chip companies just looking at the records since these S-Chips have been listed here. On the contrary only a handful stocks like Yangzijiang (high was more than S$3.00 at one time), HsuFuChi, and SunVic Chemicals worth looking but as longshots.
Seems like these Chinese companies have painted high growth stories, but still lacking of strong and mature professional corporate governances including stringent company laws and standard audit practises compared to those listed Singapore companies.
