Wall Street edges up on gains in tech, bank stocks

US stocks opened slightly higher on Thursday as Oracle boosted the technology sector and bank shares gained after the Federal Reserve raised interest rates for the first time this year.

The central bank on Wednesday raised rates by a quarter point to 0.75-1.00 per cent, responding to the continued strength in the labour market and a pick up in inflation.

However, the Fed stuck to its outlook for two more rate hikes this year and three in 2018. Shares of big US banks, which slipped on the less hawkish-than-expected stance on Wednesday, were up about 0.7 per cent.

"A less aggressive Fed was clearly the message the markets wanted to hear and indeed acted accordingly," Peter Cardillo, chief market economist at First Standard Financial, wrote in a note.

"The Fed's plan to stick to three rate hikes gave the green light for investors to focus on economic and corporate growth."

Oracle gave the biggest boost to the S&P, with an 8.3 per cent rise after the business software maker issued a better-than-expected quarterly profit.

IBM was up 1.2 per cent and was the top stock on the Dow.

The S&P information technology sector was up 0.42 per cent, giving the broader index its biggest boost.

At 9:37 am ET (1337 GMT), the Dow Jones Industrial Average was up 28.03 points, or 0.13 per cent, at 20,978.13, the S&P 500 was up 0.65 points, or 0.03 per cent, at 2,385.91 and the Nasdaq Composite was up 5.09 points, or 0.09 per cent, at 5,905.14.

The gains in technology and financial stocks helped keep the S&P in the positive territory even though seven other sectors declined.
