Whether it's the election or the Federal Reserve, investors Tuesday evening pushed futures for U.S. markets lower over fears of a future rate rise and who might become the 45th president.

The Dow Jones Industrial Average and Nasdaq were both off 0.05% at 9:13 p.m. EDT, while the S&P 500 pared 0.07%.

Investors Wednesday will be watching an afternoon announcement from the Fed after its monthly two-day meeting. While investors don't believe that the central bank will announce a rate increase, who can be sure? And they're looking for some kind of indication that the Fed will indeed raise rates next month, as expected.

Oh, and investors are also bothered by the ongoing tiff between Democratic presidential candicate Hillary Clinton and the FBI and the latest investigation into her private email server.

The jitters hit markets around the world Tuesday with the Dow off 0.58% in regular trading, while the Nasdaq fell 0.69% and the S&P 0.68%. In Europe, Germany's Dax lost 1.3%, the FTSE in London, 0.53%, and the Cac in Paris, 0.86%.

Asia also opened lower Wednesday, spooked by the U.S. fears as well as lower oil prices. The Nikkei in Japan was down 1.24%, the Kospi in South Korea, 0.88%, and the Hang Seng in Hong Kong, 0.91%, while the ASX in Australia dropped 1.02% at 9:42 p.m. EDT.

In oil, industry standard Brent crude lost 0.46% to $47.92 per barrel, while a barrel of West Texas crude lost 0.6% to $46.39. The prices represent futures for delivery in January and December, respectively, and were valid as of 9:29 p.m. EDT.

In after-hours trade, shares of Frontier Communications (FTR) slipped 3.31% to $3.80 after the communications services company turned in third-quarter revenue below Wall Street expectations.

Following today's closing bell, Norwalk, Conn.-based Frontier said revenue was $2.52 billion, below a forecasted $2.57 billion. It also reported an adjusted loss of 4 cents per share, which was in line with analysts' estimates.

For the year-ago period, Frontier reported adjusted earnings of 3 cents per share and $1.42 billion in revenue. Monthly customer churn was 2.08% for the 2016 third quarter, compared to a rate of 1.91% in the same quarter last year.

Also in extended trading, shares of Match (MTCH) retreated 2.91% to $17.34 after the online dating company reported a 2016 third-quarter revenue miss but earnings beat. After regular trading ended, the Dallas-based Tinder parent company said revenue grew 18% year over year to $316.4 million, but missed analysts' expectations of $318.0 million.

Dating revenue grew 22% to $288 million, while nondating revenue slid 15% to $28.9 million due to the new SAT test format, the company said in a statement.

Adjusted earnings of 23 cents per share beat the FactSet consensus of 19 cents per share.
