Influence of Investor Sentiment on Asset Returns: An Empirical Analysis Using Fama-French Five-Factor Framework
Abstract

This study examines how behavioral factor, specifically investor sentiment, influences stock returns in India. An aggregate sentiment index (ASI) is developed to assess its influence on stock returns, positing that sentiment constitutes a priced risk factor in India, even when accounting for the risk variables identified by Fama and French (2015). Sixteen portfolios are created based on size, book-to-market equity, profitability and investment, comprising a total of 84 observations for each portfolio from April 2016 to March 2023. The results suggest that the sentiment risk effect is not consistent across the constructed portfolios. Sentiment negatively influences the behavior of stock returns across 16 portfolios, and sentiment risk has a detrimental effect on excess returns in a portfolio. The findings provide policymakers, scholars and other stakeholders with important insights for understanding the dynamics of Indian stock market.
