Query: Weak Attempt and Misapplied Theories

There are only 3 out of 12 pertinent chapters of this book. The other 9 chapters are an extraneous rambling to take up space on paper. The author even goes as far in this irrelevant material to discuss topics such as art collecting. The pertinent chapters are not useful because of misapplied theory. For example, the author does not present the Black-Scholes methodology correctly and improperly defines profitability of an "in-the-money" option. To me this is a marketing ploy through Decisioneering.I recommend books by Johnathan Mun, Robert Hull, Richard Brealey, and the CBOT.
