Abstract

This paper examines the transmission of investor attention between firms based on geographical proximity and product market similarity using EDGAR search traffic data. We find that firms receive more attention when a nearby firm experiences abnormal attention, with the effect decreasing with distance and over time. The effect is stronger for firms in similar product markets. Effects are most concentrate among nearby firms, with attention increases exceeding 86% for very similar markets, dropping to 41% as distance increases. This research extends the literature on investor attention and local information bias, highlighting the importance of peer firm relationships in information transmission.
