Bartram, Brown, and Stulz (2016) report a strong positive correlation between systematic and idiosyncratic stock return volatilities and suggest heterogeneous firm-level responses to market wide shock may be an underlying driver. We test the hypothesis using Korean stock market data by including additional factors that reflect the macroeconomic conditions to the single factor model used in Bartram, Brown, and Stulz. Even though the correlation decreases by about 25% from 0.85 to 0.64 with additional factors, a substantial positive correlation still remains. In addition, we cannot find evidence that a high correlation industry experiences more volatile corporate sector dynamics in terms of changes in firm ranking and market share.
Abstract
Bartram, Brown, and Stulz (2016) report a strong positive correlation between systematic and idiosyncratic stock return volatilities and suggest heterogeneous firm-level responses to market wide shock may be an underlying driver. We test the hypothesis using Korean stock market data by including additional factors that reflect the macroeconomic conditions to the single factor model used in Bartram, Brown, and Stulz. Even though the correlation decreases by about 25% from 0.85 to 0.64 with additional factors, a substantial positive correlation still remains. In addition, we cannot find evidence that a high correlation industry experiences more volatile corporate sector dynamics in terms of changes in firm ranking and market share.
