Professional wealth management is a closed book ... until you ask the right questions. In his book, David Stein, himself a professional asset manager, gets to the bottom of the secret to successful investing in the form of 10 questions, including: Is it investing, speculating or gambling? Who takes the opposite side of the trade? What does it take to be successful? When readers ask themselves these questions and know the answers, two enormously important goals are achieved: a) they know they are not omniscient; b) they know they can trust themselves and their knowledge. This foundation, which professionals also rely on, paves the way for private investors to succeed on the stock market.
