Abstract: In this study, it was examined effects of alternative investment instruments and bubbles occuring in these instruments on volatility of Borsa Istanbul 100 Index (BIST 100). For this purpose, we used monthly gold price, TL/USA dollars, TL/Euro, deposit interest rate and BIST 100 Index variables over the period of 2002:1-2016:5. Sup-Augmented Dickey-Fuller (SADF) and Generalized Sup-Augmented Dickey-Fuller (GSADF) was used to determine bubbles. TGARCH model was used to determine volatility of BIST 100 index. It is infered from the analysis that increases in exchange rate and gold prices enhance the volatility of BIST 100 index. However, the bubbles in gold prices decrease the volatility of BIST 100 index.
