Solid economic fundamentals
While the outbreak has been raging, economic fundamentals have remained solid for the United States.
On Monday, the Institute of Supply Management's manufacturing PMI beat expectations and showed the first expansion for the sector since July.
US factory orders for December also beat expectations on Tuesday, rising 1.8%, compared with the consensus estimate of 1.2%.
Friday's jobs report is expected to be yet another strong showing for America's labor market, including an unemployment rate around the 50-year low of 3.5%.
With an unemployment rate this low and wages ticking higher, American consumers, who are the backbone of the economy, are strong.
On top of all this, a solid earnings season for American companies also provides a positive backdrop for the market.
