“…Overall, research suggests that such incidents cause drastic, but short-term transitory effects on stock markets, especially on the first day, with recovery in most cases occurring within one to two days (Brounrn & Derwall, 2010;Chesney et al, 2011;Drakos, 2010). Kollias, Papadaumou and Stagiannis (2011), by contrasting the stock behavior following the attacks in Madrid (2004) and London (2005), suggested that recovery may be affected by both the type of the attack, and the promptness and adequacy of the country's institutional responses, an argument that is supported by Essaddam and Karagianis (2014), and Aslam and Kang (2015). With regard to volatility, the literature suggests a significant increase for up to 15 days following the incident (Drakos, 2004;Essaddam & Karagianis, 2014), with some suggesting that this effect is larger in emerging markets (Arin et al, 2008).…”
