5 stars (Good book to understand quantitative finance) - Luenberger was a professor of optimization and his books on that subject are also very good. Clear and Precise. But sometimes he is extremely concise, so that you need to work a bit to completely understand a point. In this book, we have again the same style (after all, it is the author style): Clear and precise book, GOOD choice of notation (I cant say the same thing about HULL's books) but sometimes extremely concise. Overall, a good book to start learning and on a solid foundation. 5 stars ( Investment Science must have) - Great book, covers lots of material and goes beyond by using the log utility to portfolio growth. Great buy!!!! 5 stars (One of the few books I have purchased twice.) - This is the best book by far on the theory of finance. The book covers all the important fundamental concepts and develops them into practical models without going overboard and introducing every possible variation on the model. the style is both conversational and mathematical. It is replete with discussions about the material, but it doesnt gloss over the math. I took professor Luenbergers course at Stanford, and it piqued my interest in finance enough to pursue it professionally. (At the time, I was a masters student in electrical engineering.) I purchased several other books in finance. I dont even know where they are now, every time I have a question or need to build a new model, I go straight to Luenberger. This book is so good, I bought a second copy just as a backup, in case I lose my copy and the book goes out of print. ...
