One of my core beliefs as a portfolio manager is that we get paid to worry so investors don’t have to. Several weeks ago, Brad wrote about what was worrying investors and whether those issues were worth worrying about. He also acknowledged that there are some real concerns out there as well. I want to build on that idea and provide insight into how portfolio managers think about risks when everything seems to be going exactly as investors had hoped and, except for some short pullbacks measured in hours or days, markets continue to move higher.
