主题/Title:Investor Sentiment Measures Purged: A Necessary Double Check on Sentiment Impact
内容简介/ Abstract:
The investor sentiment measures based on market variables underperform those sentiment measures extracted from investor surveys in various applications. By purging the fundamental component out of the market-variable-based sentiment measures thoroughly, we propose a largely contamination-free sentiment measure, which no longer underperforms survey-based measures. Generally, the issue of contamination caused by fundamentals can be a hidden risk for market-variable-based measures, which may cause failures in detecting sentiment impact and misinterpreting risk-based results with behavioral stories. Overall, a double check using the contamination-free measure could be important and necessary.

主题/Title:Keynes Meets Merton: Examining Risk and Return Relation Basedon Fundamentals
内容简介/ Abstract:
The documented weak and even negative risk-return relation can be due to the nonfundamental forces against rational assumptions. More accurate measures for expected return have been proposed as remedies to address this discrepancy. Nevertheless, those remedies have mixed results since they do not control for the non?fundamentals. We control for the impact of non-fundamentals via estimating expected return based on fundamentals and obtain a positive risk-return relation. Moreover, upon controlling for the non-fundamental component, those remedies on the weak or negative risk-return relation become more robust.
