Mr. Graham’s objective of writing this book was to offer an investment policy book to all the investors, either professional or ordinary, either individual or institutional. Mr. Graham, based on his precious experience during the Great Depression, discovered that most typical investors have a behavioural tendency to “follow the market” or “follow the popularity” with different and numerous poor investment habits. They often believe they can beat the market and earn huge profits easily solely based on the unrealised profit on their accounts; however, they do not understand the companies as well as their underlying assets at all, and they do not realize the power of potential risks from different aspects.
