Abstract: In this paper, we first remove fundamental information content from Baker and Wurgler(2006) six sentiment proxies thoroughly. Then we exploit the residual non-fundamental information of Baker and Wurgler(2006) six sentiment proxies in a more efficient manner to obtain a new purged index for the purpose of explaining the expected return cross-sectionally. Empirically, we find that our purged investor sentiment index has a similar or greater power in predicting the stock returns cross-sectionally as using the original Baker and Wurgler (2006) sentiment index without removing much fundamental information content. As a result, our purged sentiment index could be considered as a better measure of a behavioural driven investor sentiment. In addition, our study show that the original Baker and Wurgler (2006) sentiment index captures a behavioural driven investor sentiment component. Therefore, it seems fine for many studies to adopt the Baker and Wurgler (2006) sentiment index with a behavioural interpretation.
