Stock markets of the member countries of ASEAN-5 (Indonesia, Singapore,

that investors often behave irrationally. One of the irrational behavior is herding
behavior, which follow the behavior of other investors or market sentiment
without doing analysis while make a sell or buy transaction.
This study aimed to analyze and detect the indication of herding behavior
in stock markets of the member countries of ASEAN-5 (Indonesia, Singapore,
Malaysia, Philippines, and Thailand). Herding detection methods in this study is
using a multiple linear regression method Cross-Sectional Absolute Deviation
(CSAD) from Chang, Cheng, and Khorana (2000). Variables that used in the
method are return dispersions, absolute market return, and the squared market
return. The data needed is the daily returns of active individual stocks and daily
return of a market index in each country.
The method to test the hypothesis is using Standard Error HAC Newey-
West. The test results of return dispersion, absolute return market, and the
squared market return using Cross-Sectional Absolute Deviation (CSAD) showed,
that there were no significant evidence of herding behavior in the stock market of
Indonesia, Singapore, and Thailand. However, significant evidence of herding
behaviour, found in the stock market of Malaysia and Philippines
