Abstract
This paper investigates how anchoring-induced investors’ trading behavior drives momentum anomaly. The results show that price momentum does not retain its ability to predict future returns after considering the stock’s nearness to its 52-week high. The stock price’s nearness to the 52-week high is a stronger return predictor for stocks with a higher retail trading proportion. This suggests an anchoring-induced momentum pattern, which is affected by investor heterogeneity. Our trading flow analysis reveals that retail investors are subject to anchoring bias. Their trading behavior causes price underreaction to good (bad) information for stocks traded near (far from) their 52-week high.
期刊介绍：
Behavioral and Experimental Finance represent lenses and approaches through which we can view financial decision-making. The aim of the journal is to publish high quality research in all fields of finance, where such research is carried out with a behavioral perspective and / or is carried out via experimental methods. It is open to but not limited to papers which cover investigations of biases, the role of various neurological markers in financial decision making, national and organizational culture as it impacts financial decision making, sentiment and asset pricing, the design and implementation of experiments to investigate financial decision making and trading, methodological experiments, and natural experiments.
Journal of Behavioral and Experimental Finance welcomes full-length and short letter papers in the area of behavioral finance and experimental finance. The focus is on rapid dissemination of high-impact research in these areas.
