I find ebooks hard to read to begin with. But this book was hard to read simply because it is a compendium of past articles written by the author. There is actually very little new in the book and it certainly is of little use to someone trying to figure out how to benefit from investing in the stock market. Quite frankly I believe the best thing to do is simply buy one of the excellent Vanguard funds and stop trying to beat the experts. As John Bogle has pointed out, almost all the experts, with rate exception, are mediocre as well.
