The debate over Market Efficiency usually destructs because the term "Market Efficiency" can really have two meanings: (1) Prices are Rational and/or (2) that investors can't consistently beat the market. "Winning the Loser's Game" is the classic that gives the philosophical underpinnings for what is born out by the empirical evidence: the markets are efficient from the 2nd perspective - investors can't consistently beat the market. If you think you can beat the market then you have to assume that you know something that all the other smart people don't know and that you can consistenly capitalize on it. Excellent read and implemented well on the Kindle. A good one to have for your intellectual tool-kit. However, would purchase and read Bernstein's "Against the Gods" first...

Just my two cents...

Generally good. Repetitious at times. Good companion book to others. I wouldn't use it as a sole source. I would recommend under these terms.
