Some books are timeless; this one isn't. The subject in its nature is dynamic and ever changing. Time for this book to retire. While the main points and recommendations in the book are somewhat insightful; they can fit into an internet article or youtube video: the rest is outdated advice or a boring (VERY boring) historical account of the stock market throughout the 20th century. 600 pages of fluff.
In every field: there are "defacto" classics that no one bothered to re-evaluate. This seems to be one of them.
