The market reaction was dramatic and swift when it became apparent early Wednesday morning that Donald Trump had been elected the 45th president of the United States. But once trading in the U.S. got underway, the S&P 500, which had plummeted as much as 7.5% in the futures market overnight, was up slightly; gold, which had soared, was little changed; and the dollar recovered from earlier losses. What didn’t rebound was the U.S. Treasury market.

The yield on the 10-year Treasury note surged to 2.06% by midday Wednesday, up 20 basis points from the previous close, suggesting that Tuesday’s Republican sweep of the White House, Senate and House of Representatives could result in higher inflation and a much larger budget deficit due to increased government spending increased coupled with large tax cuts. Then a $23 billion auction of 10-year Treasury notes was met with weak demand – the weakest since March 2009, according to Reuters.

Trump has proposed a massive infrastructure spending – double that of Hillary Clinton’s proposed $275 billion plan – but has provided few details – as well has tax cuts for corporations and individuals, especially higher earners, a bigger standard tax deduction and some additional tax credits. The net result over the next decade, according to the conservative Tax Foundation, would be a federal deficit that is $2.6 trillion to $3.9 trillion larger.

David Kelly, chief global strategist at JPMorgan Funds, said, “Actual policy changes may be far less dramatic than was proposed by Mr. Trump during the campaign” because “‘establishment’ Republicans … may well balk at unfunded tax cuts or spending increases [and] both the new President and Congress will likely act more slowly on dismantling the Affordable Care Act or trade agreements, until some better alternatives can be found.”

Carl Weinberg, chief economist at High Frequency Economics, noted in his commentary that “no one knows yet what is coming and when, or even if it is coming at all,” referring to U.S. tax, trade, immigration and health care policy. 

“It remains to be seen exactly what a President Trump can do on his own and what will require Congressional assent, and how Senator Schumer [the presumed Senate minority leader] will conduct Democrats in opposition,” wrote Weinberg. “Some companies will hold off on investments until they learn the shape of the new tax code and figure out how to ‘play’ it to their best advantage [which] could be a drag on growth.”

This uncertainty is playing out in expectations for Fed policy, which until Trump’s victory, was heavily favored to raise rates at its December meeting.

“The uncertainty and volatility following the U.S. election will, for now, reduce the probability of a Federal Reserve rate hike in December, although the Fed will want to leave its options open until it can assess the market and economic fallout from the election result,” said Kelly, but he’s not taking the expectations for a Fed rate hike off the table just yet.

Neither is Jim O’Sullivan, chief U.S. economist at High Frequency Economics. “If Fed officials were meeting today, they would not be raising rates,” writes O’Sullivan in his commentary. “We are not going to rush into changing our call for a rate hike at the December meeting…. A lot can happen in five weeks.”

Thomas Wilson, senior investment manager at Brinker Capital, told ThinkAdvisor that the investment firm is not making any specific adjustments to portfolios at this time but looking for opportunities to take advantage of when markets trade off.

Pharmaceutical, biotech and financial stocks rallied in early trading Wednesday as a result of the Trump victory, on expectations that the Affordable Care Act could be repealed and Dodd-Frank regulations could be eased.

Advisors, too, shouldn’t make any big changes in client portfolios because of the election results unless their objectives, time horizon or financial situation has changed, said Tim Clift, chief investment strategist at Envestnet on a post-election webinar. “The decision to do nothing is probably the most likely scenario for most clients, but it is important to talk to them.”

“We are late in the economic cycle,” noted Clift. “Markets will have a  more difficult time in the next years than they have had in the last four years.”

According to Bloomberg, during the first year of a new presidential term, the S&P 500 declines an average 1.15% when the president is a Republican and rises 22.15% when the president is a Democrat.
