How deep do you want to go into it? Random and hater have knee jerk reactions when the numbers tumble. Does that mean the economy is tanking or what?
Stocks tank and explode during times on uncertainty, like elections or this pandemic. It's an ongoing speculation of who is going to suffer and who profits, a bad week means nothing but trends do.
Unless you see stocks in terms of trends for each sector, you're just acting like a day trader.
I'm far from an expert, I don't claim an economics degree but I don't panic or in hater & ramdom's case celebrate, over a dow index showing scary red numbers.
