G'day DangerDarkHorse,
I think someone just wanted to take a profit and get out as the price has gone up a fair bit the last day or so! In my opinion this company has a lot going for it, I don't think it's a dud but there dos not seem to be a lot of interest in them right now they need some news and with a good deal or two in China, they will get that interest IMO! I am still holding, cheers
