To Invest Do I need to Know Beta and Option Pricing?

Investors Happy that they Don't Know Beta and Option Pricing

"To invest successfully, you need not know understand beta, efficient markets, modern portfolio theory, option pricing, or emerging markets. You may, in fact be, better off knowing nothing of these. That of course, is not prevailing view at most business schools, whose finance curriculum tends to be dominated by such subjects. In our view, though, investment students need only two well-taught courses - How to Value a Business, and How to Think About Market Prices."
