Despite stocks moving mostly lower on the last day of the year, the Dow is expected to post a double-digit annual increase, its best in three years. All three indices are poised to close 2016 with gains.

The S&P 500 was down 0.61%, the Dow Jones Industrial Average was 0.44% lower, and the Nasdaq was over 1% lower.

Although, trading volumes are light, the information technology sector was dragging markets down, falling 1% on Friday. Goldman Sachs (GS) led the Dow, adding 0.5%, while Apple (AAPL) Microsoft (MSFT) and Intel (INTC) fell over 1%, dragging it lower. 

Of the 11 S&P 500 sectors, the top gainer for the year was energy, up 23.4%. Financials jumped 19.1% and telecommunications services increased 17.1%. The only sector that declined this year was health care, down 4.2%.

"U.S. equities are ending 2016 in a reasonably good position," Terry Sandven, chief equity strategist at U.S. Bank Wealth Management, wrote in an email. "Prices have been remarkably resilient throughout the year, overcoming early-year weakness and ongoing uncertainty to end the year near all-time highs; the U.S. economy appears to be in a Goldilocks zone; and earnings are on the cusp of increasing."

The Brexit vote and the election of Donald Trump were market movers this year as investors weighed the benefits and costs of these actions. Trump's campaign promised to reduce financial regulations and cut taxes. That, combined with his Wall Street Cabinet selections, moved markets further into positive territory after Nov. 8.

Currently, the Dow is up 13.2% in 2016, a double-digit percentage gain which has happened only four times in the last 10 years and is the highest increase since 2013. The Dow was on track to hit the 20,000 milestone but retreated after hitting a record high of 19,988 on Dec. 20.

The S&P 500 is on track to close with a gain of 9.5% for the year, moving away the double-digit percentage gain, which would have been the sixth in the last decade. The Nasdaq is poised to close the year with a gain of 7.3%.
