講題: New Market Entry, Trademarks, and Stock Returns
As a proxy for firms’ entry into new markets, trademarks involve significant ambiguity, such as contestability, renewal, and market acceptance, and past experience/statistics may be irrelevant. Therefore, owing to ambiguity aversion, firms with more newly registered trademarks can be relatively undervalued. Empirical evidence shows that new trademarks strongly predicts higher abnormal stock returns. Furthermore, this return predictive power is stronger among more ambiguous/complex firms, such as larger, R&D-active, and low advertising firms, and is stronger among firms with newly registered exploratory trademarks. These results suggest that the stock market tends to undervalue new trademarks due to ambiguity aversion.
