In this study, we investigate the effect of public information arrival on return volatility for Borsa Istanbul. New information arrival is measured by the number of daily news headlines for Turkey, the United States, and a sample of European countries with close trading ties with Turkey. We classify news headlines by country and type of news. Our findings indicate that, during a recessionary period, new information arrival causes return volatility mostly to decline. Moreover, both economic news and European news cause a significant decline in volatility persistence. However, when news is classified based on origin and type, a larger decline in persistence is observed.
