We investigate the relationship between innovation indicators (R&D and patenting) and stock market performance for a panel of manufacturing firms traded on Borsa İstanbul (BIST), formerly known as the İstanbul Stock Exchange. Similar to previous results obtained using U.S. and European data, we find that larger R&D stocks are associated with higher market value, higher market-to-book ratio, and higher price-earnings ratio for firms traded on Borsa İstanbul, while larger patent stocks are associated with higher market value. We demonstrate that it is possible to use the information on R&D and patent stocks to construct a portfolio that greatly overperforms the market index (BIST100).
Key words: Innovation, R&D, patents, market value, Borsa Istanbul, BIST, portfolio selection. JEL Classification: O31, O33, O34, G11. Article Language: EnglishTurkish
