June 8 (Reuters) - Wall Street was little changed in a narrow trading range late on Wednesday morning, with the S&P 500 inching towards its all-time high, as oil prices gave up some early gains.

The energy index, which led the market higher at the start, reversed course to trade down 0.11 percent.

Waning prospects of a near-term rate hike pushed the dollar lower for the fourth day in a row, which in turn boosted commodities. Gold rose to a near three-week high.
"I think the good news for the market is that the sentiment is still far from euphoric. So if you have data just chug along and no major shocks, you could potentially have the market gap higher," "said Marc Pouey, U.S. Equity and Quantitative Strategist at Bank of America in New York.
