It was a huge loss when the Stockholm Stock Exchange closed on Monday. The OMXS index fell 2.1 percent. As a result, almost all year-end is erased.

It is the concern about the development of the corona virus in China that is causing the world's stock exchanges to reverse significantly. And after Monday's fall in Tokyo, unrest spread to the European stock exchanges.

The Frankfurt Stock Exchange's DAX index fell 2.7 percent, as did the CAC40 index in Paris. The London Stock Exchange's FTSE100 index in turn backed 2.3 percent. The travel industry in the form of airlines and hotel companies is one of the sectors most affected.
