How A Second Grader Beats Wall Street by Allan S. Roth

Don't let the title put you off. "How A Second Grader Beats Wall Street" is worth reading and adding to your library, especially for those not happy with their investment performance, those tired of paying excessive fees to investment advisors, and DIY Investor Newbies. Complex topics are simplified. The chapter on locating investments to minimize taxes by paying taxes at the lowest rate and avoiding taxes until they have to be paid will save many readers a lot of money.
Full disclosure: the book is centered on the investment philosophy I believe most investors should follow - focus on asset allocation, invest with low cost indexed exchange traded funds or mutual funds, and participate in broad markets.
It presents an approach that has handily outperformed professional managers over the long-term.
A portfolio constructed by applying the ideas in the book can be found at Paul Farrel's lazy portfolio site.
