observed, in other words, the cross section would decrease the standard deviation in descending
or rising markets, could not be confirmed and it was concluded that herd behavior was not
encountered with the method used in the data set. |

While
the VIX index was previously followed by investors from developed countries, it is now followed by investors who evaluate their investments in developing countries. In this study, it was examined the effect of price movements in the VIX index on the stock markets of the developing (BRICS) countries between the dates of 02.24.2011 and 06.01.2020.
