100 Year Thinkers: Chris Davis and Robert Hagstrom on Holding Great Companies, Index Risk and Who Really Wins From AI
Chris Davis and Robert Hagstrom explore the tension between holding great businesses and keeping a winning stock from becoming too much of a portfolio risk. Why do two investors who believe in letting winners compound also use 10% position limits? On this episode of 100 Year Thinkers, Chris Davis of Davis Funds and Robert Hagstrom of EquityCompass join Matt Zeigler and Bogumil Baranowski to discuss position sizing, selling mistakes, index concentration and the cost of growth. From Chris Davis’s experience selling Costco to the debate over who will capture AI’s economic benefits, they examine what it takes to hold a business through uncertainty without ignoring risk. Stay for Matt and Bogumil’s closing discussion of the lessons for investors.
