This book is like a time machine that will take readers back to the past investment world: Graham mentioned the depression of the railroad industry and the rise of the aircraft manufacturing industry. He also predicted that there would be a boom in the real estate market after World War II. Graham often warned the public that it was dangerous to try to predict the future, and he failed to foresee the technological changes after the war and the economic boom that followed.
After all, history has much to teach us. Despite this, Graham's ideas continue to be embraced and admired by the largest and most loyal investment community of the 20th century. The more I study his value investing principles, the more I respect him.
Buffett wrote the preface to the fourth edition of "The Intelligent Investor", in which he mentioned: "The stupider the market behavior, the greater the opportunity for smart investors. Following Graham, you will profit from the stupid behavior of the masses without letting yourself become one of them." This sentence expresses the value of reading Graham's works.
