If you had a company requiring Bromide, why wouldn't you buy from your other comapny since it is a basic comidity? Did GM buy generators from Delco?
I think a recent pronouncement by Burp or Joenatural (can't remember which one) that they had some data on GURE is positive. I suspect that Struftepete1 (who lives in Taiwan) and has contancts on the mainland, has some data on production. Some of it has been posted here. I suspect good earnings and for a company with a PE of 1.6 that should have some positive results.
I know, I know, 'Think', 'suspect', too much guesswork here. Yes, but with China that's all we have most of the time.
