In May of 2011, Columbia Business School Publishing published Howard Markss The Most Important Thing. Distilling the wisdom of Markss celebrated client memos into a single volume and, for the first time, making his time-tested investing philosophy available to general readers, the book was widely acclaimed by professional, casual, aspiring, and armchair investorsand became a business bestseller. Columbia Business School Publishing is announcing an innovative digital edition with a print version of Markss volume that allows readers to read the authors words alongside the comments, insights, and counterpoints of four renowned investors and investment educators: Christopher C. Davis (Davis Funds), Joel Greenblatt (Gotham Capital), Paul Johnson (Nicusa Capital), and Seth A. Klarman (Baupost Group). These experts lend insight into such concepts as second-level thinking, the price/value relationship, patient opportunism, and defensive investing. Marks also adds his own annotations, expanding on the books original themes and issues.
