Categorical Thinking and the Experience Effect: Evidence from Price-Based Return Predictability
A new study reveals that investors often group stocks by price, not just by financial data, and this behavior can predict future returns. The research highlights stock splits, where companies lower share prices by dividing shares, as a key example. After splits, investors treat the lower-priced shares as a new category, influencing trading and valuation. The findings challenge the idea of fully rational markets and suggest that price-based thinking shapes asset pricing and return patterns.
What it examines
This paper studies how people use price categories and their past experiences to predict stock returns. The authors focus on stock splits to see if price-based categorization affects return predictability, using data analysis to explore how these behavioral factors influence financial markets.
What it concludes
The findings show that price-based categorization, especially after stock splits, drives return predictability. This suggests investors' mental shortcuts impact market outcomes. Applications include improving trading strategies and understanding market anomalies. Future research could explore other behavioral effects and test these ideas in different markets or asset classes.
Evidence objects
New research reveals investors often categorize stocks by price, not just financial metrics, and this behaviorshaped by personal market experiencecan help predict future stock returns more accurately.
