Abstract
We study how professional investors use social networks to impound price-relevant information into asset prices. Exploiting novel data from an online social network that facilitates information sharing among fund managers, we find that long (short) recommendations released into the private network generate cumulative abnormal returns of 3.61% (-4.90%) over a twenty-day window. These results suggest that social networks play a direct role in facilitating the price discovery process.
