Wall Street Maintains Gains Despite Renewed Inflation Jitters

U.S. shares ended higher on Wednesday even after minutes from the Fed's December meeting showed concerns that quicker economic growth under President-elect Donald Trump could require faster interest-rate increases to ward off inflation.

U.S. stocks have surged over the past two months on expectations that Trump will stimulate the economy with tax cuts and infrastructure spending, and eliminate regulations in the financial industry.

But investors also worry that Trump's measures could stir inflation and push the U.S. Federal Reserve to raise interest rates more aggressively than anticipated.

"Clearly, some of the members on the committee are taking a look at proposed fiscal changes, whether that's tax cuts or infrastructure spending," said Chris Zaccarelli, Chief Investment Officer for Cornerstone Financial Partners. "It's confirmation of what people were already expecting."

Extremely low interest rates have fueled rally of over 200 percent in the S&P 500 since the 2008 financial crisis, and investors worry that raising rates will crimp future increases.

With just over two weeks left before Trump takes office, and the Dow Jones Industrial Average closing in on the never-before-reached 20,000 mark, investors also say they need to see evidence that his campaign-trail promises will be approved by Republican lawmakers.

The Dow Jones Industrial Average rose 0.3 percent to end at 19,942.16 points, while the S&P 500 gained 0.57 percent to 2,270.75.

The Nasdaq Composite added 0.88 percent to 5,477.01.

Since Trump unexpectedly won his bid for the White House on Nov. 8, the S&P has gained over 6 percent and the Dow has rallied nearly 9 percent.

In Wednesday's session, the materials index rallied 1.38 percent, its best day in nearly a month.

The S&P 500 consumer discretionary sector rose 1.33 percent, helped by gains in automakers. Both General Motors and Ford rose over 4 percent after posting better-than-expected U.S. sales in December.

Nine of the 11 major S&P 500 sectors were higher, with just the energy and telecommunications sectors at a loss.

Gilead Sciences jumped 2.99 percent after the biopharmaceutical company named a new oncology chief.

Comcast rose 1.19 percent after Macquarie raised its price target.

Advancing issues outnumbered declining ones on the NYSE by a 5.84-to-1 ratio; on Nasdaq, a 3.44-to-1 ratio favored advancers.

The S&P 500 posted 27 new 52-week highs and no new lows; the Nasdaq Composite recorded 160 new highs and 18 new lows.

About 7.0 billion shares changed hands in U.S. exchanges, more than the 6.8 billion daily average over the last 20 sessions.
