Input: Consider Input: Some textbook! . This is the longest textbook I have in my collection and it is also a bad investment book at that. I know some readers really enjoyed the detailed explanations, but the book was too detailed and wordy for me. Many of the explanations are unnecessary and examples can be simplified to get to the core of the problem/concept and drive at a much stronger intuitive understanding. But this book doesn't do that. It is cluttered with definitions and wordiness that kill the intuition one could get by reading a more concise, straightforward text. A really good book is Investment Science, by David Luenberger. Although his text assumes you have some background in calc/stat/probability theory, the writing, examples, and organization is far superior. You'll actually begin to understand how investment really works, without getting bogged down by the numbers, terminology, and jargon

Output: NEG


Input: Consider Input: Excellent, Informative! . Keeping it brief, this is a great book with tons of interesting facts about mysteries that are in the Bible. Explanations of miracles, detailed history surrounding them. I learned an intense amount of information in this book. You don't have to be a scholar, as it was written simply. The authors did an excellent job

Output: POS


Input: Consider Input: In your head. . It got inside my head... and has not left after a year


Output: POS
