Why Amazon, Walmart and Target may be good stock buys right now

CNBC's Kelly Evans discusses the market action after Black Friday and as vaccine hopes weigh on investment decisions going into 2021 with David Harden of Summit Global Investments and Nancy Prial of Essex Investment Management. There are some overbought positions, says Harden. Look at Amazon, which is up over 70 percent. People are shopping online, which is very, very positive for that company. There are some companies out here that are overbought, he says. So I'd be very careful here.
