Investors looking for response to Russia allegations

U.S. stock futures were trading flat Wednesday as investors stayed on the sidelines ahead of a much-anticipated news conference from President-elect Donald Trump.

Markets have advanced since Trump's election in early November, with major indexes hitting repeated records, although that rally has shown signs of stalling of late, with some analysts worried that the gains have gotten overdone. If Trump attempts to tamper down expectations, or if he fails to reassure investors about the recent allegations comments that Russia may hold compromising information (http://www.marketwatch.com/story/russia-may-hold-compromising-information-on-trump-cnn-reports-2017-01-10) on him, that could spur heavy volatility.

"If the press conference does not give direction to the markets, then this consolidation could continue to Trump's inauguration next Friday," said Richard Perry, market analyst at Hantec Markets, in a note.

Dow Jones Industrial Average futures dipped 3 points to 19,785, while those for the S&P 500 index dipped 2.2 points to 2,261.50, while Nasdaq-100 futures were flat at 5,031.25.

The Nasdaq Composite reached its fourth-straight record close on Tuesday (http://www.marketwatch.com/story/us-stocks-stuck-in-waiting-game-ahead-of-trumps-news-conference-2017-01-10), closing up 20 points to 5,551.82, marking its longest streak of all-time highs since Dec. 27, 1999, according to Dow Jones data. But the S&P 500 finished flat at 2,268.90, while the Dow industrials , which came within 43 points of the 20,000 level earlier in the day, closed off 31.85 points to 19,855.53.

Trump's news conference--expected at 11 a.m. Eastern Time (http://www.marketwatch.com/story/what-time-is-donald-trumps-press-conference-on-wednesday-2017-01-11)--will be his first formal news conference since July. As Perry pointed out, markets are "hoping for further clues over the direction of fiscal policy, which has had so many hopes pinned to."

The cautious tone for markets comes after an exuberant postelection rally that finished 2016 on a high note. Trump's victory spurred hopes that he would advocate for deregulation and tax cuts, which are seen as policies that could accelerate economic growth.

Some investors may be waiting to see whether Trump comments on allegations that Russia may hold compromising information (http://www.marketwatch.com/story/russia-may-hold-compromising-information-on-trump-cnn-reports-2017-01-10) on the president-to-be and that Russian agents conspired with Trump campaign advisers and some of his company employees. The president-elect has dismissed the reports as a "total political witch hunt" on Twitter (http://www.marketwatch.com/story/trump-blasts-russian-allegations-as-total-political-witch-hunt-2017-01-11).
