Sept 14 (Reuters) - Wall Street rose on Wednesday, supported by gains in technology stocks and in tandem with the recent oscillation as investors fret over interest rates.
Apple shares were up 3.1 percent, giving the three major indexes their biggest boost and rising for the third day in a row on reports of strong demand positive review for the new iPhones.
The technology sector was up 0.8 percent, topping the eight gainers among the 10 major S&P 500 indexes.
U.S. stocks have swung wildly since Friday on contrasting comments from Federal Reserve officials on whether the central bank would raise interest rates at its Sept. 20-21 meeting.
The benchmark S&P 500 index fell 1.4 percent on Tuesday after having gained by a similar measure on Monday. The index had fallen 2.45 percent on Friday.
“With a seasonal backdrop, high valuations and concerns over disparate monetary policies by central banks, it will likely remain a choppy environment,” said Eric Wiegand, senior portfolio manager at the Private Client Reserve at U.S. Bank in New York.
The CBOE Market Volatility index, known as Wall Street’s fear gauge, has also spiked and dropped with the stock market’s gyrations. The index was down 3.47 percent on Wednesday.
At 11:04 a.m. ET the Dow Jones industrial average was up 39.1 points, or 0.22 percent, at 18,105.85.

The Nasdaq Composite was up 32.77 points, or 0.64 percent, at 5,188.03.
“The cyclicals are doing well and that points to an underlying appetite to participate in the market, with the feeling that there is still some compelling valuations,” Weigand said.
Oil prices dropped 1.9 percent, sending the S&P energy and materials indexes down by 2 percent each.
Monsanto agreed to be bought by Bayer, but its stock rose just 0.82 percent as anti-trust concerns surrounding the deal.
