After reading 3 or 4 Buffet oriented books years ago, I found them to paint a very faulty picture of how he actually made his money and built the BH fortune.
The conventional wisdom on Buffet offered in these books is that after working with Graham (or was it Dodd?...anyway) he applied these value investing criteria and a buy and hold strategy over a few decades and made a killing.
But this is marginally true at best. The conventional wisdom ignores that Buffet used the ability to leverage businesses he owned or controlled to acquire other businesses at discounts you would never see as a typical investor acquiring shares in the open market. For example, how many of us are going to go out and buy an entire furniture company or candy company? Yes, the acquisitions were based on being undervalued. But to assert that what he did is akin to an average Joe applying a value/buy-n-hold strategy is highly misleading.
Save your money and buy a book that will teach you something, not spin some faulty and misleading tale. If you want to brush up on fundamental type topics, give Mises' Theory of Money and Credit a spin sometime. It will be a better use of your time, IMHO.
