Global stocks have fallen on Monday in the wake of the Paris attacks, with travel and tourism companies leading the drop.

French companies were hit the hardest, with Eurotunnel Group and Aeroports de Paris falling almost 5%. Airlines were also amongst the biggest the fallers, with budget airlines Easyjet (LON:EZJ) and Ryanair (LON:RYA) falling around 3 percent. Air France (EPA:AF) is down 5 percent and British Airways owner IAG (LON:IAG) is down 3.4 percent. The tourism sector accounts for about 7.5 percent of French GDP.

Asian shares also experienced a disappointing day, with the Nikkei stock index falling nearly 1.1 percent, almost wiping out last week’s 1.7 percent gain. The Hang Seng is also down 1.72 percent.

French financial markets are open again today, with extra security measures in place for staff – especially in the La Defense business region of Paris.
