In my book, The Warren Buffetts Next Door, I call Kai The Scorcerer’s Apprentice because he has managed to become a master investor working as the manager of a computer lab at a prestigious business school. Kai has no fancy degrees but rather he is a self-taught quant, who has developed his own winning stock screening formula incorporating the theories he has learned on the job. Like a magpie, Kai has cobbled his strategy together listening and learning from others. He has nine portfolios on Marketocracy.com, and as of March 31, 2010 every single one had long term performance records better than their relevant benchmark indexes. In this video he recently filmed near his home town of Sault Ste. Marie Kai explains his approach.
