I'm not sure why some reviewers have given this so few stars, when they seem to agree that its actually quite a good introduction to valuation techniques. Its not perfect, but I can't name a better starting point.
The author doesn't claim to go in to huge amounts of detail. As he says, himself, there are other texts for that. He recommends "Modern Methods of Valuation", and I would agree with that.
He clearly explains to the complete novice the theory behind the main valuation techniques, in an idiot-proof manner.
If you have already progressed beyond a basic level, you may find some of the chapters somewhat patronising. But if you are a beginner still struggling to get your head around the baisc concepts and the maths behind them, you will probably greatly appreciate the very clear explanations.
Overall this book is a good introduction, that's all the title claims to be, and it does it very well. To expect more is a little unfair.
