Abstract

In light of changes in the media landscape from traditional print towards social media, in this study we compare the ability of investor sentiment measures obtained from various media sources to predict short-term market returns. We show that investor sentiment extracted from the social media platform Seeking Alpha is better in predicting market returns than investor sentiment obtained from the Wall Street Journal, a traditional print medium. Seeking Alpha is more suitable for the extraction of investor sentiment due to the richer language and timeliness of online media.
