The R&D investments represent a company’s unique expenditure, which is responsible for creating an information asymmetry about the firm’s growth potential and future prospects. In a case when market value reflects only the firm’s financial statements without taking the long-term benefits of R&D investments into consideration, the company’s stocks may be underpriced. On the other hand, the firm’s stock prices may also face overpricing. This might happen in a case when the investors judge the possible future outcomes of current R&D investment based on the past firm’s R&D success, which is not a guarantee by any means.
So, is there a premium among firms with intensive expenditures on R&D or not? If so, does R&D expenditures represent a robust risk factor, or are there any other hidden economic forces that could explain the R&D premium? This article tries to answer these questions by revisiting and expanding the three previously conducted research papers on R&D premium.
