Özet: This paper aims to investigate the causal relationship between investor sentiment and stock returns on Borsa Istanbul (BIST). We analyze the changes in Consumer Confidence Index as a proxy for investor sentiment and changes in the BIST-100 return index, employing both the conventional and time-varying recursive evolving Granger causality tests. The monthly data covering January-2004 – September-2018 are analyzed. Contrary to the findings of the conventional Granger causality tests, the recursive evolving Granger causality tests indicate bi-directional causality relationship between the time-series. We detect Granger causality running from BIST-100 to Consumer Confidence Index, starting in December-2015 and continuing until the end of sample period. Moreover, the recursive algorithm detects Granger causality running from Consumer Confidence Index to BIST-100 occurred in February-2018, lasting for two months. The investors, portfolio managers, and policy makers in Borsa Istanbul should consider investor sentiment as an additional source of systematic risk.
