Like Donald Trump's campaign over the last year, the U.S. stock market has had its highs and lows.

Wednesday, stock futures plunged after it became clear that Trump was going to be the 45th president.

But today, they've surged.

Investment Manager at Pinnacle Wealth Management, Casey Franken says after an election, abnormal activity in the stock market it usual.

He says this one can be blamed on Hillary Clinton losing.

He says many of the markets were priced according to a Clinton win, so as soon as Donald Trump started to look victorious, the markets substantially dropped.

After the election, some of the markets have risen.

And that's because of the differences in Trump and Clinton's policies.

For example, yesterday the pharmaceutical industry stocks were down and the gun sector was up.

Today, it's the opposite.

Which means it may not be the best time to invest.

"The average investor in a 401k that just wants to know, should I buy sell hold, we would advise to make sure you know what you own and be smart about making moves during this time period,” says Franken.

Franken says other examples of stocks that rose overnight are the health care and financials sectors.

He says the stocks will continue to be abnormal for the next couple of days.

The Dow Jones Industrial average hit a new all-time high today, trading 100 points higher than yesterday.

The S&P 500 gained nearly half a percent.
