The interaction between stock prices and corporate investment: is Europe different?

I find limited evidence of firm learning from stock prices in Europe and uncover multifaceted complementarities between firm informational and operating environments in determining investment sensitivity to stock prices. Specifically, European firms seemingly do not shift away from their own (peer) stock prices even in instances in which their peers’ (own) stock prices become relatively more informative about firms’ fundamentals. This is consistent with European managers adopting more conservative strategies relative to their U.S.-based peers, and stock prices being less revealing in Europe than in the U.S. Furthermore, while a firm may attach equal weight to both its own stock prices and peer price innovations when peer firms are relatively smaller, investment responds more positively to peers’ price shocks than to that firm’s own stock prices when peers are relatively larger. Interestingly, investment sensitivity to peers’ stock prices decreases in peers’ market share, operating performance, and capital intensity. The decrease is accentuated when peer firms have more informative stock prices and are industry leaders or more capital intensive, thereby signaling perceived reduced growth opportunities. Broadly, these results imply that the specifics of the interaction between stock prices and firm behavior in the U.S. do not necessarily generalize to Europe. More important, these different learning patterns are partly attributable to differences in the amount of internal information, which in turn depends on country-level institutional infrastructures.
