Dow 20,000 remains elusive for traders

U.S. stock futures pointed to a flat start for Wall Street stocks on Tuesday, with many traders still away for the Christmas break, and a scant week for economic data.

Dow Jones Industrial Average futures futures slipped 10 points to 19,864, while S&P 500 futures fell 1.25 points to 2,258.75. Nasdaq-100 futures fell 1.5 points to 4,940.75.

Ahead of the extended holiday break, the Dow industrials booked the seventh straight weekly gain (http://www.marketwatch.com/story/us-stock-futures-point-to-holiday-induced-slumber-but-banks-may-be-on-the-move-2016-12-23) in muted trade onFriday. The Dow and S&P 500 each rose 0.1% on Friday, while the Nasdaq-100 gained 0.3%.

Investors would be forgiven for cashing out on a year that surprised many with a late-year run of gains following the U.S. presidential election. The Dow is up 14.6% with just a few days left to trade in 2016. The S&P 500 is up 4.4% and the Nasdaq Composite has gained 2.8%, year-to-date.

The Dow has come close to the all-time high of 20,000, but that level remains elusive for the index.

For Tuesday, Case-Shiller home prices for October are due at 9 a.m. Eastern Time, while consumer confidence data for December is scheduled for 10 a.m. Eastern.

"The Conference Board consumer confidence index is already at the highest level since before the 2008 financial crisis and is expected to rise further. That would be a positive indication of the 'Trump effect' on the financial markets," said Marshall Gittler, head of investment research at FXPrimus, in a note to clients on Tuesday.
