Quotes

• “"Any graduate of the ___ Business School should be able to beat an index fund over the course of a market cycle."Statements such as these are made with alarming frequency by investment professionals. In some cases, subtle and sophisticated reasoning may be involved. More often (alas), the conclusions can only be justified by assuming that the laws of arithmetic have been suspended for the convenience of those who choose to pursue careers as active managers.”
• “The central question for positive financial economics is valuation – what is the value today of a set of future prospective cash flows? The central question for normative financial economics is the appropriate use of financial instruments in a world in which values are set wholly or partially in accord with the principles of positive financial economics.”
