If I just took out the facts of this industry whatever you want to call it, sector, you know ten years ago there were none. Now there are over 2,000 and if I gave you that fact and then I showed you the charts of 100 of them or a thousand of them and they all go straight up you would say whatever what is that that's a bubble, whether it's cotton or Brazilian stocks or whatever it happens to be you would say that's a bubble. So it looks like a bubble but bubbles can go on a long time a lot you and they often do but just because it looks like a bubble doesn't mean it's the end of the story.
