摘要：

This study addresses the issue whether day traders' recommendations on stocks are biasfree. We test whether on average day traders' "Hold" sentiment is skewed and different from a neutral opinion. Posted messages and mature text classifier technology provide a novel approach to analyze the content of these "Hold" sentiment postings among day traders. Findings indicate that the self-disclosed "Hold" sentiment conveys an optimistic opinion and significantly differs from neutral. These results help both investors and researchers to better understand day traders' psychology and behaviors when they recommend stocks. The paper also provides insight into the construction of future online sentiment indexes based on stock message boards. © Springer Science + Business Media, LLC 2008.
