Event study method, terror attacks, global equity marketsAbstract
This article examines the effects of fifteen major terror attacks perpetrated in the U.S. and Europe between 2001 and 2017 on a general global stock market index as well as on industry-specific indices, namely (1) airlines, (2) global hotels, restaurants, and leisure (hospitality), and (3) global utilities. Using an event-study method, we show that attacks tend to result in significant negative abnormal returns on the day of attack which, on occasion, persist for a few days. As expected, adverse market effects appear more pronounced, in terms of magnitude and persistence, for the global airline and hospitality industries than for the global utilities industry. Attacks in Europe since 2015 show no adverse global market effects, with two late exceptions (the London Bridge and Barcelona attacks, both in 2017). This might suggest that just when investors and markets seemed to have learned to cope with attacks, these two latter events caused some concern again. Implications of our findings for short- and long-term global investor strategy are discussed.
