Uncertainty is known to be crucial in asset pricing, yet evidence from comprehensive analysis of various uncertainty measures remains sparse. This paper investigates the predictability of stock returns based on economic fundamentals uncertainty by constructing a novel uncertainty index derived...

Using the long-term wavelet component of monthly S&P500 excess returns as supervision information, we employ a partial least squares method to extract the common predictive information of 14 prevalent macroeconomic variables, and construct a new macroeconomic index aligned for predicting stock...
