Market Myths and Mathematical Realities
A Quantitative Analysis of Unscientific Trading Indicators
Luigi Pascal Rondanini
Wall Street loves a good omen. Almost every one of them is noise. This book puts the market’s best-loved indicators on the dissection table and runs the numbers the way they should have been run all along. Some collapse at the first significance test. A stubborn few survive. None deliver the easy money their believers promise.
