After reading various authors on investing, O'Neil's materials seemed to remain relevant, insightful, and without fluff. Another IBD devotee on a message board mentioned this book as a must read and source for his recent success, so I requested it from the library. It is a short read, with mostly charts of past models of short sells. O'Neil's explanations of why and how to be on the look for proper shorts are only a couple pages long, but should pique your awareness of the other half of investing aside from "buy and hold".
