I don't see a huge risk for a short attack. The risk reward situation is simply not good enough from a short perspective, least to say.
As you stated, we don't have shares available on OTC. The valuation of the company is ridiculous even if you say that Siaf including the 18.3% of the Tri-way shares that will remain in Siaf after the stock dividend, would be worth zero.
People like myself would gladly pick up shares if opens down 15 % or more without news.
The shorter will also face the risks that Siaf release news regarding form F1, financing for TW, international partnership for CA with a strong founding partner. Or SJAP finds founding partners that want to capitalise on the monopoly situation regarding value adding processing given be local government to SJAP.
If any of above happens, the shorter is fu**ed.
