Are the effect of the coronavirus on the stock market could be opportunity for investing? The SP500 went down 8% this past 5 days. I'm wondering if that will go lower those next days.

I have a bit amount of money on the side, I didn't know where to invest. Would now be a good opportunity to lump sum all the money, or would you Dollar Cost Average?

Anyone else with the same dilemma, and would have more arguments? Or maybe an other perspective on that?
