U.S. stocks surged more than 1 percent Wednesday with financials and health care leading after Republican Donald Trump won the presidential election, defying market expectations for a Hillary Clinton win.
The day's rally took the major averages within 2 percent of their all-time intraday highs, and marked a stunning recovery from a sharp plunge in stock index futures overnight. Trade volume Wednesday was the highest since the surprise U.K. vote to leave the European Union in June.
"Overnight was all about uncertainty. Today we know" the result," said JJ Kinahan, chief strategist at TD Ameritrade.
The Dow briefly rose more than 300 points in the afternoon, on track to close at a record high and about 25 points below its all-time intraday high. Caterpillar and Goldman Sachs contributed the most to gains.
The S&P 500 traded 1 percent higher after falling initially, with financials advancing 4 percent to lead advancers. "Within financial services, there is a guarded view that there may be less regulation [under Trump] than under a Clinton presidency," said John Stadtler, head of U.S. financial services at PwC.
The Nasdaq composite rose about 0.9 percent.
"We had a trial run in June with the Brexit vote," said Scott Clemons, chief investment strategist at Brown Brothers Harriman. "Like with Brexit, investors and traders are realizing that this is a process, not an event." "What you're seeing right now is a pretty predicable repositioning of portfolios."
Investors began adding exposure to health care and defense stocks, both of which saw significant pressure heading into the election, since Clinton was the favorite to win.
Stock futures had pared the lion's share of their losses before the open. Dow futures traded about 200 points lower after briefly shedding more than 800 points overnight. S&P and Nasdaq futures also slashed losses, trading around 32 and 96 points lower, respectively.
"The market's initial response to the probability of a Trump win was, predictably enough, one of shock and fear as the prices of traditionally risky assets tumbled and perceived safe havens rose. However the increased prospect of tax cuts and a generally pro-growth set of policies from him, aided and abetted by the Republican clean sweep of congress, has seen some of this initial reaction begin to reverse," James Athey, fixed income fund manager at Aberdeen Asset Management, said in an email.
