Sidebar: "Gene" is Professor Eugene Fama. He is a finance professor at the Booth School of Business at the University of Chicago. I was first introduced to Gene through my econ curriculum at Williams College.

Gene won the Nobel Prize in Economic Sciences in 2013. Gene is a smart man. I believe what Gene says.
