Traderfan:
not to be pollyannish, but when everything looks very bad, is likely to be the point at which a turn comes.
You are of course correct regarding the poor outlook for China, the difficulty in getting loans, and the overall downtrend in the larger market.
Since I am convinced that SIAF has huge potential, I am buying these dips, so that when some catalyst event does happen, I will not be chasing. Days like this, with dramatic drops on low volume, allow traders like me to pick up some shares on sale--- I hate paying retail!!
