U.S. stocks fell on the last trading day of 2016, eating into gains for the year, following a decline in technology stocks. The S&P 500 technology sector’s 0.7 percent fall put the broader index on track for its third straight day of losses – the longest losing streak since Nov. 4. The Dow Jones Industrial Average, which came within 13 points of breaching the 20,000 level last week, is now more than 200 points away from the milestone.
