Stock herding in the financial markets is defined to be the tendency to mimic other investors and their decisions. In our study, the herding
behavior in the Philippine Stock Exchange is detected in the
market-level using the CSAD Method by Chang et.al. (2000). The study
contributes in the limited literature in the Philippine stock market herding by observing market level herding, market conditions that could affect herding (extreme market conditions, level of trading, size of firm), and finally the sector- and sub-sector-level of herding. The study found significant evidence of herding
in the up markets as well as during high volumes of trading. However,
for the level of sectors and market capitalization, there is no herding. There is significant herding
in subsectors like Other Industrials and Telecommunications. The study
recommends further studies by dividing analysis between individual and
institutional investors, or by observing changes in stock price during
periods of market announcements and news.
