Hi,
Can there really be any doubt that Reminiscences of a Stock Operator, by Edwin Lefevre, is THE "best" investment book of all time? There is sound advice to be pondered in each & every chapter of this classic. DON'T DEPEND ON "TIPS"!!!
Besides being chock-full of timeless knowledge, Reminiscences is extremely well written. It's a "page-turner." Based on the early life of one of the greatest traders ever, Jesse Livermore, this biography depicts a corrupt & rapacious Wall Street which doesn't exist anymore (??) You can still learn a whole lot from Lefevre, even though this book was origially published in 1923.
(also, you can learn to try not to marry a showgirl...) (THAT advice is not in this book, but there is a glut of information about Livermore available, mostly because of this "exquisite pleasure" of investment literature.)
