The Theory of Finance in a Nutshell

Using a few simple and basic principles, the main results of the modern theory of finance are obtained, from CAPM to option prices, from risk neutral valuation to intertemporal model, non-expected utility and behavioral finance. The basic intuition inside the valuation equation is that the price of any asset is the sum of the prices of the moments of its probability distribution multiplied by their quantity. This set-up can lead to classical results but it is also capable of several important and easy-to-think generalizations which can be proved useful from both theoretical and practical points of views.
