Could we get together a list of companies that are publicly traded with ticker symbols, recent prices, etc. CDT has gone to Sumitomo chemical, and all I can find is Aixtron (AIXG) and Universal Display (PANL). Samsung is available, but which company (electro-mechanics or electronic or the distribution company) and Sony is possible, but oled might be just a drop in the bucket for such large companies. There must be some S.Korean companies with or without ADRs. Manufacturing, research/development, and sales companies could be on this list.
