GM shares jump after the auto maker raised its earnings outlook for 2017

The Nasdaq Composite notched its fourth record close in a row Tuesday, representing the longest stretch of record closes for the tech-heavy index since 1999.

Fresh all-time highs for the Nasdaq came as the Dow industrials failed to reach the psychologically significant level of 20,000 again, amid otherwise tepid enthusiasm for equities ahead of a news conference from President-elect Donald Trump set for Wednesday--his first since being elected on Nov. 8.

But the Nasdaq CompositeIndex shined, finishing up 20.00 points, or 0.4%, at 5,551.82, for the sixth straight day in the green and marked its longest streak of all-time highs since Dec. 27, 1999, according to Dow Jones data.

Meanwhile, The S&P 500 index ended at its flattest level in years, unchanged from Monday at 2,268.90. The broad-market gauge had been up by as many as 10 points earlier in the session. Five of the 11 main sectors closed lower, bookended by a 1.3% decline in the real-estate sector and a 0.4% gain in consumer-discretionary stocks.

The Dow Jones Industrial Average , which had traded up by as many as 70 points and within 43 of breaching the 20,000 mark earlier in the session, closed down 31.85 points, or 0.2%, at 19,855.53. Shares of Merck & Co.(MRK) and Exxon Mobil Corp.(XOM) dragged on the benchmark.

Beyond, Trump's comments, which could add clarity to his legislative agenda, market participants are awaiting the kick off earnings season for some support for the recent rally in U.S. stocks.

The market is looking for confirmation of stock valuations at current levels, and the only way to get that will be upbeat earnings, said Peter Cardillo, chief market economist at First Standard Financial.

Some of evidence of pre-Trump news conference jitters were on display in the dollar , which pulled back somewhat on Wednesday. The greenback was up about 0.1% against major currencies. The dollar has been rising on hopes that the new administration's fiscal stimulus will boost the economy, but some analysts believe that bet may have been pushed too far, too fast. (

( ("In thenear term, there are a lot of things to worry about. For example, we might hear some chatter from the corporations about the sharp rise in the dollar, which will have an impact on their earnings in the next few quarters," said Maris Ogg, president at Tower Bridge Advisors.

Ogg, however, isn't worried about stock markets over the next few years, in part because of expected deregulation.
