Market gurus are prominent in the financial community, and their forecasts often influence how people trade. Today we discuss a recent study by David Bailey, Jonathan Borwein, et al. that investigates the accuracy of these market predictions. They introduce a new method for evaluating forecasts, where forecasts are weighted based on the timeframe and specificity of prediction. They found that 48% of all the forecasts tested were correct and that 66.1% of the forecasters had accuracies below 50%.
