The book is not very useful for the people residing outside US. But you want surface idea about how investing was introduced and basic idea of investing you can start with this book. But if you are not US resident look for better option.
Quality of the book is worst but the content isn't. great book for anyone who willing to start explore on how the stock market works. since it is from the heart of American investor, lots of stories(which you may skip) of US companies which we have unheard of.
