We propose that innovative originality is a valuable organizational resource, and that owing to limited investor attention and skepticism of complexity, greater innovative originality may be undervalued. We find that firms' innovative originality strongly predicts higher, more persistent, and...

We analyze 7.7 million patents via textual analysis to develop a novel patent-to-patent measure of innovation similarity among firms. With this measure, we investigate whether stock price movements reveal information about firms' technological connectedness. We find that investors impound...

We examine the relationship between sentiment and Mexican stock market returns. Results suggest a positive dynamic relationship between rational Mexican sentiment and equity market returns. Results also reveal a spillover of US sentiment on the return generating process of the Mexican stock...
