By Phin UphamHow does one analyze something as complex as investing from a global perspective? Sometimes it’s easier to see what others don’t see by looking at the forest instead of the trees. For instance, if there was a contest to see which professionals could predict what would be the tallest tree in the forest ten years from now, how would different professionals approach the competition? The botanist who specializes in tree species might select the fastest growing tree. An immunologist, someone who specializes in tree disease, might notice a certain disease in the forest and select the tree that was immune to it. An expert in soil, or a pedologist, might go for the tree planted in the most fertile land. Youtube and Slideshare.
