The Dow Jones Industrial Average on Wednesday closed above the psychologically significant threshold of 20,000. Finishing at the level represents a milestone for the blue-chip gauge and highlights a relatively speedy path higher for the stock market in the wake of Donald Trump’s election win in November.

The Dow DJIA, -0.87% is up about 9.5% since Trump’s Nov. 8 election victory, the S&P 500 index SPX, -1.11% has gained nearly 7%, while the Nasdaq Composite Index COMP, -1.07% has advanced roughly 9% during that period.
