As other reviewers have noted, the poor copy-editing is embarassing. But even with all the typos, the information presented is very useful.A fairly good over view for me I am just beginning to learn about the stock market, and all the other dimensions that go along with it. I found this book quite informative, I have read it two times now. I use this as a text book to study from. I am also reading other books on the subject to make sure the information I learn is correct.
