摘要
The seminar presents two projects. The first is to provide a comprehensive analysis of the information content from options markets for predicting the cross-section of stock returns, and show why existing factors fail to pricing assets adequately. The second proposes an employee sentiment index, which complements investor sentiment and manager sentiment indices, and finds that high employee sentiment predicts a subsequent low market return. The economic driving force of the predictability is distinct from those of investor sentiment and manager sentiment: high employee sentiment leads to high contemporaneous wage growth due to immobility, which in turn results in subsequently lower firm cash flow and lower stock return.
