You can't. The best you can do is to build a market thesis that represents your views, try to find reasons that you are wrong to help harden / shape your views, and only then try to find others that believe the same way your thesis does to try to see how they predict. Everyone has their own crystal ball, and everyone believes theirs is the right one. If you look at fintwit, you will see "the world is ending", "the worlds ended, we going up", and "lets wait and see". At least a few of them will get it right, to some extent or another. I dont think you can figure out at this time which is the right one. So, best you can do is form your own thesis I think. I've formed mine. It helps me not panic when things are temporarily against me.
