CNBC offered a list of some must-read exposés on the inner workings of Corporate America. Among the picks: Conspiracy of Fools, about Enron (and my second favorite book of all time behind A Separate Peace), Barbarians at the Gate, Liar's Poker and The Predator's Ball. These are all excellent books, and I'm embarrassed to say I've read every book on CNBC's list, which is probably part of the reason I don't have a girlfriend. However, I have some additional favorite Wall Street exposés. Oftentimes, you can learn as much about investing reading these books as you can reading the more expository books; and these ones are about 20 times more interesting:
Andy Kessler's Running Money and Wall Street Meat: These two cover the author's exploits as an analyst working alongside the likes of Jack Grubman, and his later career as a hedge fund manager focused on Silicon Valley stocks. They read crisply, and are great for the beach.
Once in Golconda and The Go-Go Years, both by John Brooks: These two, along with anything else published under the Wiley Investment Classics label are great. The first covers Wall Street from the Roaring Twenties through the Great Depression, and the second covers the Go-Go 1960s, when momo-managers like General Tsai rose rapidly, and then crashed just as quickly. Order the Wiley edition so you get Michael Lewis's foreword.
