This chapter attempts to determine whether there was herding behavior in the nine frontier markets included in the MSCI EFM Central and East Europe and CIS Index during the period 2011–14. Although the characteristics of these markets could suggest a strong mimetic behavior, the results do not seem to confirm this. On the one hand, using different methodologies, we find clear evidence of herding (at an individual market level) only within the Estonian market, although some other markets also show evidence of herd behavior in some extreme or fairly extreme quantiles of the return dispersion distribution. On the other hand, we find that the Bulgaria, Kazakhstan, Ukraine, and Croatia markets are more likely to herd around a global area consensus (the MSCI EFM Index) during both turbulent and calm periods. These results reveal the difficulty of characterizing herding behavior.

This table reports the quantile regression estimates for the markets belonging to the MSCI EFM Central and East Europe and CIS Index by different quantile groups according to Eq. 10.4.
where CSADt is the equally weighted cross-sectional absolute deviation of returns, and Rm,t is the equally weighted market portfolio return at time t. γk,τ refers to the kth coefficient conditional on the τth quantile distribution in the estimated equation. For reasons of brevity only the results for γ2 are shown. α and γ1 are positive and significant for all countries and quantiles. A significant negative value of γ2 suggests the existence of herding. Numbers in parentheses are t-statistics. ***, **, and * represent statistical significance at the 1, 5, and 10% levels, respectively.

This table reports the quantile regression estimates for the markets belonging to the MSCI EFM Central and East Europe and CIS Index by different quantile groups according to Eq. 10.5.
where CSADt is the equally weighted cross-sectional absolute deviation of returns and Rm,t is the equally weighted market portfolio return at time t. γk,τ refers to the kth coefficient conditional on the τth quantile distribution in the estimated equation. D is a dummy variable which takes a value = 1 if Rm,t < 0, and 0 otherwise. For reasons of brevity only the results for γ3 (panel A) and γ4 (panel B) are shown. α, γ1, and γ2 are positive and significant for all countries and quantiles. A significant negative value of γ3 suggests the existence of herding during bullish markets, while a significant negative value of γ4 suggests the existence of herding during bearish markets. Numbers in parentheses are t-statistics. ***, **, and * represent statistical significance at the 1, 5, and 10% levels, respectively.
