It is a 6 month outlook.
Yes the supply chain disruptions could take 6 months to correct.
If you are widget manufacturer and other companies need your widgets to make their final products and you are located domestically in the United States and all of your China competition is closed for the Wuhan Flu. Your business is going to explode, you are going to need to hire people to keep producing 24.7 and if possible expand production. Your suppliers are going to need to expand production as well.
In the long run, this could be a boost.
This might be a lesson to corporate America to not throw all of their eggs into the China basket.
But right now, things look bad, but in 6 months things will look great again. However people think things will be as bad 6 months as they are today.
