Quote from barney_collier:
If you're into options, the options book by Katz and McCormick is remarkably unlike most others. Unlike McMillan, Trester, and dozens of others, it ISN'T filled with graphs of value-at-expiry versus stock-price-at-expiry. Instead it's got fresh new ideas about analyzing options positions, and thus it suggests new options trading strategies. It's worth the price of the book just for the mind-expansion you get from reading it. Even if you never put on a single one of the trades.
