Pros: Easy to read & forever applicable.
Cons: Haven't found a good used Hardcover edition yet...
During a losing streak that was The Year of Our Lord 2010...I scoured cyberspace looking for investment book recommendations; this book was, by far, the most mentioned, condoned, and positively reviewed.
Pre-Lefevre, I had assumed that trading had completely changed since this work was first written almost a century ago. Now I know better. Besides an ever-evolving ruleset, the game hasn't changed; there's just different players and different tools. That's part of what makes this book a timeless investment classic, as it has been for generations.
If you're a trader/investor or perhaps aspiring to be one...and you haven't read this book...YOU PROBABLY SHOULD.
