U.S. stocks open higher as Fed meeting begins

U.S. stocks opened higher on Tuesday as the Federal Reserve started its two-day policy meeting.

The Federal Open Market Committee (FOMC) began the highly-watched meeting Tuesday, and will release its post meeting statement at 2 p.m. Wednesday.

The U.S. central bank is widely expected to raise interest rates for the first time since June 2006. Analysts believed that the market has fully factored in the expected December rate hike.

"Calm is slowly spreading through financial markets on day one of the two-day Fed meeting, with global equities a little higher, bond yields backing off their flight-to-quality levels and oil finally finding a bid," chief economist at FTN Financial Chris Low said in a note.

On the economic front, the Consumer Price Index (CPI) for all urban consumers was unchanged in November on a seasonally adjusted basis, on par with market estimates, reported the U.S. Labor Department Tuesday. Over the last 12 months, the all items index increased 0.5 percent before seasonal adjustment.

The index for all items less food and energy, often referred to as the core CPI, rose 0.2 percent in November, the same increase as in September and October.

Shortly after the opening bell, the Dow Jones Industrial Average rose 34.21 points, or 0.20 percent, to 17,402.71. The S&P 500 added 9.81 points, or 0.49 percent, to 2,031.75. The Nasdaq Composite Index gained 36.66 points, or 0.74 percent, to 4,988.89.
