Sector valuations matter. Right now the companies with some decent growth are trading at 20% of book. The ones that don't, 10% of book. SIAF is trading at 34% of book, so the market does recognize the superior growth rate. And it is in a wait and see mode now. But I would say it's trading in line with the sector.
KGJI, at 13% of book is exactly in line with the sector. Well, if they do well going forward then it's a good buy.
NUIN at 6.3% of book should be trading at 30%. Because they are making a lot of money and there could be a hidden growth story as well. No dilution and a lot of cash. If they announce a dividend, the stock will jump 200%. Any other press release that the market likes, up 100%. A buy-out, 1000%. You need a bit of luck in life.
Of course longer term SIAF is the right play. Because the market doesn't understand about their competitive advantages.
