Wall Street opens little changed as the rally loses momentum

• Defensive sectors rise in early trade on Wednesday. 
• Energy shares underperform ahead of weekly EIA report.

Major equity indexes in the United States started the day little changed on Wednesday as investors seem to be taking a step back following the latest rally that lifted Wall Street's three main indexes to fresh all-time highs. As of writing, the Dow Jones Industrial Average was unchanged on the day at 27,495 points, the S&P 500 was adding 0.05% and the Nasdaq Composite was erasing 0.1%.

Among the 11-major S&P 500 Sectors, the Real Estate Index, which posted heavy losses amid rising US Treasury bond yields earlier this week, is staging a technical recovery and was last seen up 0.6%. On the other hand, the Energy Index is down 0.4% ahead of the Energy Information Administration's (EIA) weekly oil market report.
