March 19 (Reuters) - Wall Street's main indexes climbed on Tuesday, as investors hoped for a more accommodative policy stance at the end of the Federal Reserve's two-day meeting this week.
A flurry of downbeat economic data this month has supported market expectations that the Fed may reinforce a halt to further interest rates hikes. The meeting concludes its deliberations with a news conference on Wednesday.
Of particular interest to investors is the individual interest rate forecasts of policymakers, as well as any details on plans to reduce Fed's holdings in bonds.
"We're seeing stocks run up a little bit in anticipation of the Fed announcing no hike in 2019 and a curtailment of the balance sheet runoff," said Bryan Reilly, managing director at CIBC U.S. Private Wealth Management in Boston.
The consumer discretionary sector provided the biggest boost to the benchmark S&P 500 as Amazon.com Inc rose 1.9 percent.
Also supporting markets were technology stocks.
Rate-sensitive financial stocks rose 0.24 percent, boosted by the big U.S. lenders. The bank sub-sector gained 0.26 percent, up for the fifth straight session.
At 11:15 a.m. ET the Dow Jones Industrial Average was up 119.12 points, or 0.46 percent, at 26,033.22, crossing the 26,000-point mark for the first time since March 4.
The S&P 500 was up 9.47 points, or 0.33 percent, at 2,842.41 and the Nasdaq Composite was up 23.66 points, or 0.31 percent, at 7,738.13.
Among the 11 major sectors, defensive utilities and real estate were the only two in the red while consumer staples was flat.
Optimism that the Fed will remain less aggressive in raising rates and hopes of a resolution to a bitter trade dispute between the U.S. and China helped the markets claw back most of their losses from late last year.
The benchmark S&P 500 is at a five-month high and is just 3.1 percent away from its record closing high in September.
Nvidia Corp rose 3.7 percent and boosted the Philadelphia SE chipmakers index by 1.19 percent after the chip designer partnered with Softbank Group Corp and LG Uplus Corp to deploy cloud gaming servers in Japan and Korea.
Fox Corp dropped 3.5 percent after its debut on the Nasdaq, marking a new phase for billionaire Rupert Murdoch's media business after the $71 billion sale of Twenty-First Century Fox Inc's film and television assets to Walt Disney Co.
Advancing issues outnumbered decliners for a 1.27-to-1 ratio on the NYSE. Declining issues outnumbered advancers for a 1.01-to-1 ratio on the Nasdaq.
The S&P index recorded 31 new 52-week highs and no new low, while the Nasdaq recorded 48 new highs and 20 new lows. (Reporting by Medha Singh and Shreyashi Sanyal in Bengaluru; Editing by Shounak Dasgupta)
