The Globe and Mail says in its Saturday edition that for most people, the word "psychopath" conjures up the Hannibal Lecter sort, but it just as often describes executives in upper management. The Globe's Tim Shufelt writes that consider Alex Karp, the jittery, sword-waving billionaire chief executive officer of what some call the "scariest company in the world." Palantir's name comes from the stones in the Lord of the Rings books that are ultimately used to spy on and control the people of Middle Earth. On literal Earth, Palantir's software is used for things such as locating immigrants for deportation or collecting vast amounts of data on Americans. If you want to be chilled to your core, watch an interview with Mr. Karp, in which he frequently talks of fear, violence and killing people. But no one ever said fear does not sell. Palantir's revenue is on track for a 54-per-cent increase this fiscal year, with free cash flow of around $2-billion (U.S.). If your adviser has been saying you need to diversify into stocks that scare the living hell out of you, Palantir is the name for you.
