Sept 7 (Reuters) - The Nasdaq touched a record intraday high on Wednesday, helped by gains in technology shares, while the S&P 500 index and the Dow were little changed.
The technology index rose 0.2 percent and hovered near its highest level since 2000, after Facebook hit a record high on a Morgan Stanley upgrade.
Western Digital jumped 9 percent and was among the top percentage gainers on the S&P and the Nasdaq after the company raised its profit forecast for the first quarter.
The Federal Reserve is scheduled to release its Beige Book - a summary of commentary on economic conditions - later in the day that will be parsed by investors for rate-hike clues.
"We've had three to four pieces of relatively disappointing economic data, so that puts some focus on today's Beige Book," said Art Hogan, managing director of Wunderlich Equity Capital Markets.
The markets are going to be in a wait-and-see mode until the Fed comes to some consensus of a rate hike in December, Hogan said.
Traders have priced in a 15 percent chance of a hike in September and a 45.7 percent chance in December, according the CME Group's FedWatch tool.
The dollar index was trading flat on Wednesday after falling more than 1 percent a day before. Oil prices also rose about 0.45 percent.

Apple shares were up 0.19 percent at $107.89. The biggest company by market value is expected to unveil the new iPhone 7 later on Wednesday.
Chipotle rose 5.2 percent to $435.51 after activist investor William Ackman's hedge fund Pershing Square bought a 9.9 percent stake in the burrito chain operator.
