I stumbled into Paul Merriman when he was a guest on another podcast which led me to his podcasts and web site. I found his research very interesting and as a guy who likes numbers, his "tables" pretty informative. His Ultimate Buy & Hold Strategy really caught my attention, especially how he illustrates moving in small steps from 100% S&P 500 to his suggested ideal portfolio. Any of you fans of his or subscribe to his approach? A little more involved mind you with some additional funds to buy and rebalance, but pretty compelling.
