We investigate whether the number of patents, classified by exploitation and exploration activities, can complement corporate R&D expenditure in explaining stock price movements (SPM). Based on unique corporate patent data, we empirically find that the number of patents have more significant explanatory power in explaining SPM than R&D expenditure. Our results indicate that incorporating the number of patents in explaining SPM could add value.
