What Investors Need to Know Since Dow Crossed 20,000

The Dow Jones Industrial Average finally hit the critical 20,000 level Wednesday. The stocks that contributed to the Dow's march to 20K, since the election, include Apple (AAPL) - Get Report , IBM (IBM) - Get Report , Visa (V) - Get Report and American Express (AXP) - Get Report . Scott Berman, a portfolio analyst with Action Alerts PLUS, said the notion of Dow 20,000 is more of a symbolic development.

"It's a really big day for the entire stock exchange," Berman said. "It really began after Donald Trump was elected."
