What does everyone need to know about investing, including the people who have no interest in it? In this episode, host Tano Santos is joined by two previous guests and longtime friends of the show: Jenny Harrington, CEO of Gilman Hill Asset Management, and Jenny Wallace, co-founder and Chief Investment Officer of Summit Street Capital Management. Harrington co-edited Investment Wisdom For Our Friends And Loved Ones, a collection of 25 essays written for the friends and family who keep asking where to start, and the conversation uses the book as a map of the ground anyone should cover. The three discuss why the mechanics of investing are far easier than the psychology, Warren Buffett's test for a wounded athlete, why holding too much cash is its own form of market timing, and how to read financial news without mistaking noise for signal. Each guest also closes with the one name she is thinking about right now, and much more!
