We show that a firm’s stock return is predictable by R&D activities of other firms in the industry, and that such predictability is related to investor inattention to cross-firm information. We identify industry “R&D Leaders” that have a burst of R&D activities as well as “Peers” that are in the same industry but do not have substantial R&D increases. We find that Peers experience significantly positive abnormal returns and abnormal operating performance in subsequent years. They also positively surprise investors at the time of earnings announcements. Further, Peers with stronger economic links to Leaders experience higher abnormal stock returns. Finally, abnormal returns to Peers are concentrated in those having low investor attention, with an annual four-factor alpha of 8.4%.
