Forecasting returns with fundamentals-removed investor sentiment

The Baker and Wurgler (2006) sentiment index purports to measure irrational investor sentiment, while the University of Michigan Consumer Sentiment Index is designed to largely reflect fundamentals. Removing this fundamental component from the Baker and Wurgler index creates an index of investor sentiment that may better capture irrational sentiment. This new index predicts returns better than the original Baker and Wurgler index as well as the alternative Baker and Wurgler sentiment index.
