actually I think the stock at 0.85 is holding up currently quite well as a pinkie, better than many Nasdaq and OTC stocks in this space.
It's trading at a forward P/E of 1.9 based on a 2011 guidance eps of 0.45 (expected NI of 30.6m and fd of 68.5m as announced in the Sweden conference). I personally would be very happy if Company can achieve 80% of its lofty 2011 revenue target of 57.7m. That's for me an expected 2011 eps of about $0.34 (vs $0.136 for 2010 including rev of discontinued ops, still very respectable). That implies a forward P/E of 2.5. I think the market is probably more skeptical, resulting in an even lower eps expectation and a higher forward P/E.
For comparison, the current forward P/E of many CGS Nasdaq stocks is around 2 , so SIAF is not in any way undervalued at current prices IMO.
Based on guidance # of 2011 earnings, the forward P/E is:
GURE 1.97
CCCL 2.07
NEWN 1.88
YONG 2.91
SIAF 1.9 based on 100% of guidance NI
SIAF 2.5 based on 80% of guidance NI
SIAF 3.8 based on 50% of guidance NI
