Aug 3 (Reuters) - The S&P 500 and the Nasdaq fell on Thursday, weighed down by Amazon.com, Apple and other top-shelf technology stocks, while the Dow Jones Industrial rose marginally and was on track for a record high close.

The S&P 500 information technology index, which has led other sectors in 2017, dipped 0.28 percent. Apple lost 0.90 percent after hitting a record high the day before. It and Amazon.com, down 0.97 percent, weighed more than any other stocks on the S&P 500.

Silicon Valley electric carmaker Tesla jumped 6.50 percent reporting quarterly results above Wall Street's expectations.

Analysts on average expect S&P 500 earnings to have grown 11.8 percent and they project earnings up 9.2 percent for the September quarter, according to Thomson Reuters I/B/E/S.

The S&P 500 has risen 11 percent in 2017 and is trading at 18 times expected earnings, pricey compared to its 10-year average of 14, according to Thomson Reuters Datastream.

"Earnings are supporting this market and consumers are supporting it from a macroeconomic standpoint," said Phil Blancato, CEO of Ladenburg Thalmann Asset Management. "This is a Goldilocks economy, good enough to push the market higher, no bubbles in sight."

At 2:14 pm ET, the Dow Jones Industrial Average was up 0.07 percent at 22,032.38, which would be a record high close.

The S&P 500 lost 0.19 percent to 2,472.79 and the Nasdaq Composite dropped 0.28 percent to 6,344.96.

Wall Street has shrugged off a recent failure by a Republican-controlled Congress to overhaul healthcare as well as doubts about how easily President Donald Trump will be able to fulfill promises to cut taxes and increase infrastructure spending.

"There was a time earlier this year that the market was politically driven. I think the market is just numb to it at this point, said Matthew Peterson, Chief Wealth Strategist for LPL Financial at Charlotte, North Carolina.
