Dec 31 (Reuters) - U.S. stocks fell at the open on Tuesday,
as a Wall Street rally fizzled out in the final days of the
decade after growing trade optimism and a brightening global
outlook put the S&P 500 on track for its best year since 2013.
The Dow Jones Industrial Average .DJI fell 47.50 points,
or 0.17%, at the open to 28,414.64, shrugging off a tweet by
President Donald Trump that a Phase 1 U.S.-China deal will be
signed at the White House on Jan. 15. The S&P 500 .SPX opened lower by 6.11 points, or 0.19%, at
3,215.18. The Nasdaq Composite .IXIC dropped 27.26 points, or
0.30%, to 8,918.74 at the opening bell.
