Query: Content free

To even to most junior quant, this book would be content free. What's more, he promises the revolutionary new Calamos valuation method (now, not even Nobel prize winners name their theories after themselves, they let other people do it for them, so already, suspicion) but again, nothing, just some snapshots from the screen of his software. The book blurb is misleading, it actually promises the method, not just an advert for it. Do not buy this book, you will learn nothing.
