Query: Bogleheads: A Book That Makes Sense Out of Wall Street

There is nothing like a Bear Market to get you to question a lot of things about the wonderful world of investing. Having said that, this book which focuses on the ideas of John Bogle is just the ticket to set you straight on a number of critically important investment concerns. Asset allocation, the importance of having the lowest costs, how the mutual fund businss really works, it's all here and it all makes perfect sense. I wish now that I had heard more of the wisdom that this man has been passing along for so many years while inventing index funds at Vanguard Investments. I highly recommend this book to anyone who wants to invest with greater confidence and success for the long term. It may well change the way you think about the world of Wall Street and investing. It did for me.
