What Do Hedge Funds Think of Technical Analysis?

What do hedge funds think of technical analysis? Corvin Codirla, ex-hedge fund manager and independent traders comments. Do you need to be good at maths to make money trading? Why aren’t economists wealthy / successful investors? Or are they? Some of them love it and some of them hate it. It also depends what you mean by technical analysis. If technical analysis means optically looking at charts and looking for patterns like head and it becomes very difficult to test. If something cannot be written down in a set of rules, then it is not useful. Others will argue that technical analysis is more of an art than a science. Knowing maths doesn’t necessarily make you smart.
