I am learning how to invest in options and I have bought "Options as a Strategic Investment," but is there a book that is considered the "Best Options Analysis" book out there?
McMillan, then Natenberg, then Cottle. That progression of authors will take care of you very well. "DAGNYT" may try to sell you on his book(s).
