The purpose of this paper is to show that the consequences of terrorist attacks are beyond what is reported in the media. Equity investors can be adversely affected by these incidents. The authors' work justifies the war on terror.
Using event study methodology, the authors test how abnormal returns have changed for industrial portfolios in Indonesia following the recent terrorist attacks in the USA, the UK, Spain, India and even Indonesia. The authors adjust the CAPM to test whether systematic risks are altered around these events.
The findings show that equity portfolios were adversely affected by the September 11 attacks and Bali bombings. The domestic terrorist attack generated the worst outcomes. It appears that systematic risk has increased by the amount of terrorist risk. Other attacks in London, Madrid and Mumbai were minimal.
This study shows how domestic and international terrorist events affect the risk and return in an Asian capital market.
