Coronavirus is affecting global stock markets

The NZX 50 Index has fallen more than two percent in the first hours of trade, as concerns grow over Covid-19.

The ASX 200 has also slumped, and the Dow Jones has had one of its worst single day losses in years.

Craigs Investment Partners Mark Lister says people shouldn't be acting out of fear of a pandemic.

He says there are no reason to panic or change investment strategies.
