$Novo Nordisk AS(NVO.US) From my current perspective, Novo Nordisk is my biggest investment failure. I can give you ten thousand reasons why it shouldn't be this way, but the market is never wrong. The stock's performance can't be described as bad; it's downright terrible. With so many quality companies to choose from in the U.S. market, I just had to pick you. It seems you only learn the hard way by stepping into one pit after another.
