Everyone knows that the person I admire the most is Elon Musk–for his genius and his ambitious goal of bringing mankind to Mars–but he’s not my modern day hero. The fact of the matter is, that I attribute the latter to Eugene Fama. Now if you have no clue of who he is, I’d ask this question: “Do you remember CAPM?” If you don’t, then you’re already lost. If you do, then you’re in luck. What he came up with (along with Kenneth French) is way better.
